External source of energy imposes greater restrictions on the applicability of this tool in extreme situations. Need a great time for delivery and preparation of this tool to work, the impossibility of long-range transport from the engine to the compressor due to the limited length of high-pressure hoses, which imposes restrictions on the operation of them in remote places, in fires, in addition to the inability to start the engine in strong smoky and polluted areas and the difficulty of its launch in severe cold, also it has limited functionality in this tool there is no percussion instrument.Also known instrument (scissors, brakes) see the description of the patent in Germany N 3809640 class. B 23 D 29/00, 29/02, 1988, This tool consists of an actuating mechanism including pivotally United with the axis of the rotary cutting (decompresses) the upper and lower knives, gear mechanism with the V gear, the drive mechanism including a drive piston high pressure, the actuator piston, low-pressure systems, pressure relief valves, low and high pressure, a stationary handle and a built-in capacity with gidravlicheskiy functions (only cutting and unclamping), the inability to change or replace other actuators that perform various functions, a large labor-intensive cutting and substantial period of time of one cycle (compression - resgate knives), due to the fact that it is necessary to pump the hydraulic fluid, in addition this tool is very complicated in design, which should be reflected in their reliability and, according to the authors, should have a large mass.Closest to the claimed complex pyrotechnic multifunctional instrument (hereinafter referred to as the instrument) to the technical essence and the achieved effect according to the authors are portable pyrotechnic scissors (pyrotechnic tool) that are listed in the description of the patent (19) RU (11) 2070483, (13) C1, (51) 6 B 23 D 17/02, 29/00 and adopted by the authors for the prototype.They contain connected together in a single unit Executive, drive and trigger mechanisms. The actuator includes a stationary bottom knife, pivotally connected to the axle with the upper knife, which, in turn, via a shackle connected to the slider. The drive mechanism includes a housing, which houses a spring-loaded rod with a piston that interacts with the slider ispolnina connected to the drive mechanism and includes a spring-loaded trigger with the hammer back and other elements, and has the ability reusable single shot, Samovodene work with one cartridge inserted into the cartridge chamber of the drive mechanism.This device is devoid of faults belonging to the above counterparts. It is Autonomous, not dependent on external energy sources. However, it has disadvantages, namely: limited functionality of this tool; the inability to carry out work under water; the impossibility of repeating the operation of this instrument.These shortcomings are due to the fact that the data is portable pyrotechnic scissors have as actuator only scissors that does not provide the whole complex rescue operations in extreme conditions, where you often need something to decompress, to lift, to hit, to punch or to expand.This unit does not have the ability to work under water, as it can be filled with liquid, which is not compressible medium, and type of actuating mechanism does not allow for his work in a liquid environment, for several reasons.This unit has a single, reusable, Samovodene, trigger mechanism, when the throne, in some cases it is inconvenient to do in mittens or fire gauntlets, because the cartridge is small and awkward to hold, especially in extreme conditions or in the dark (night time).The basis of the invention laid the solution, aimed at creating a comprehensive pyrotechnic tool for multipurpose works in emergency situations, rescue operations and other conditions, providing a comprehensive stand-alone works, having the ability to change actuators, as well as the ability to work under water, besides providing along with single shot work the possibility of repeating the operation, without requiring replacement of the cartridge after each operation.To solve the problem in known (pyrotechnic tool) portable pyrotechnic scissors, containing interconnected actuating mechanism including upper and lower knives with the body, interacting with the slider drive mechanism with a spring-loaded valve accommodated in the housing and single shot kurkovas mechanism having a detachable connection with a drive mechanism made in the form of swivel clamp is moveable is also with knives, unclamping with two levers, Jack with swivel locking lever, shock actuator with a punch, chisel and hammer, and others connected with the slide and having meghrashen connection with one side of the drive mechanism, made in different designs, to work on land and underwater, with the second side of each drive mechanism has the ability to connect with both single-shot and repeating kurkovye mechanisms with similar interchangeable docking sites.At the same time the difference of the complex pyrotechnic tool is that meghrashen connection of the actuators with drive mechanisms implemented in the form of grooves and projections, made in the housing and the slide actuators that interact with mating grooves and projections, made in the rod and the housing of the drive mechanisms and the fixed locking nut.In addition, the rod of the drive mechanism, providing the opportunity to work under water, made airtight chamber with a spring-loaded piston is filled with air at atmospheric pressure and simultaneously installed in the housing of predohranitelno scissors with the upper and lower knives, cutting pliers with knife, unclamping with two levers, Jack with swivel locking lever, shock actuator with a punch, chisel and hammer and other mechanisms connected to the slider and having meghrashen connection with one of the sides of the drive mechanism, has allowed us to create a versatile tool that provides Autonomous large complex emergencies in emergency situations, regardless of external conditions associated with the provision of access to victims, opened or preventing destruction of structural elements, eliminating the need for both analogues have with each actuator his drive, additionally, this proposal significantly expands the possibilities of the application of different (additional) actuators, including actuators percussion.Execution of instrument drivers in different designs in the form of drive mechanism for operation on land similar to the prototype and the drive mechanism for operation under water has greatly expanded the possibilities for application of the tool, providing a wide range of works under water, however constructive it iagnostic connection of each of the drive mechanisms of the second side with a single lever mechanism and repeating lever mechanism having a similar interchangeable docking sites, helped to enable the delivery tool with a single lever mechanism is quite acceptable to a number of services that perform a specific set of works, and repeating lever mechanism having advantages in the absence of the necessity of insertion of the cartridge after each operation.Execution meghrashen connection of the actuators with drive mechanisms in the form of grooves and protrusions in the housing and the slide actuators that interact with mating grooves and projections made in the rod and the housing of the drive mechanisms and the fixed locking nut, helped to ensure the replacement of actuators, for a short period of time. You need to Unscrew one cap nut, remove the inserted actuator in its place insert the other and screw unscrewed the cap nut, which is much faster than swapping two high-pressure hoses and replacement of the actuator together with the actuator.Run rod drive mechanism that provides the ability to work under moderamen in the case of the safety membrane and execution of drainage holes helped to create immediately before the cartridge volume of air, when the piston chamber is directly in front of the cartridge, as a preliminary effort banana its springs are designed up of pressure fluid to a depth of 60 m (6 ATM), at the time of actuation of the actuator when there is excess pressure, the piston moves, giving the amount necessary for combustion of gunpowder, then there is a mechanism, similar to the operation of the drive mechanism for operation on land. Water in podpornoy cavity is expelled through the drain holes.In case of a leakage in the chamber and filling it with water, for safety set safety membrane, which, in case of abnormal operation breaks down, then you need to land to fix the leak and install a new membrane, restoring the health of the instrument.In Fig. 1 shows a General view of the complex pyrotechnic multifunctional tool (Executive scissors mechanism, the drive mechanism for operation on land and single-shot trigger mechanism in the dock state, the other mechanisms shown in undocked);
