Trigger mechanism is installed on small arms of a carriage-mounted gun of a bullpup configuration with prior recoil of a firing device inside its guide bed, equipped with the right and left gun handles. A trigger mechanism comprises the following: a figured spring-loaded slider trigger element with two triggers, a muzzle ledge, acting at a transversely moving spring-loaded strut of a full bent in the front position of the firing device, and a breech ledge of the trigger element acting at the strut. The breech ledge is installed on a spring-loaded cam available on the slider trigger element. The breech and muzzle full cocks of the slider trigger element are installed at the distance, the value of which provides for locking of the spring-loaded hinged cock in the cocked position immediately after the first shot in the "fixed" burst firing mode. The trigger mechanism comprises a cock moderator to reduce the firing rate in the "burst of arbitrary length" mode. The longitudinal figure slider trigger element is placed on the carriage-mounted gun equipped with a basic longitudinal metal element, which carries the movable firing unit and metal bases of weapon gun handles. The return spring of the trigger element is placed on a breech rod of the slider trigger element with a rest of the muzzle end at the crank transition of the trigger element, and of the breech end - at the breech wall of a seat for this spring.

The invention relates to a device gun weapon systems and can be used to simplify the design and improve the reliability of their machinery. A device of the recoil mechanism (VM) small arms gun "Cliff", which contains the clutch, manual connecting rod installation, fixing and resistant areas, back-and-combat spring and other parts. The clutch serves as a stop for the spring, has a decorative outdoor groove, which is installed and fixed on the rod (see Manual 12.7 mm machine gun "Utes" (NSV-12.7), Military publishing house of the Ministry of defense of the USSR, Moscow, 1978, p.16). The unit is adopted for the prototype. The disadvantages of the prototype are: the complexity and unreliability of the return mechanism associated with the split form of the coupling, which complicates the technology of its manufacture, reduces its strength and affects working conditions spring - bearing in cut clutch is missing, which can lead to deformation of the parts and the deterioration of reliability of all of the recoil mechanism. The task of the invention is to simplify the design and increase the reliability of the recoil mechanism. The technical result obtained by carrying out the invention, is to perform closed-form couplings provide the complete support of the recoil and reliable fixation of parts of the recoil mechanism. This technical result is achieved by the fact that the recoil mechanism of small arms, containing the coupling groove, the step of connecting the rod with the installation, fixing and thrust areas, as well as a return spring, it is new that the groove in the clutch is made of a closed-loop shape, and the rod is arranged to pass through the groove of the coupling on the stepped areas, thus covering the size of the cross section of the installation section of the rod is smaller than the width of the groove of the coupling, the locking section of the rod is made of faces, and the dimension between faces less, and covers the size of the faces larger than the width of the groove of the coupling. Clutch return mechanism of small arms may be provided with annular ribs. Execution of the groove couplings of closed form provides full support for the return spring, which improves the reliability of the mechanism, increases the strength of the coupling and simplifies its manufacturing technology (may reduce requirements for material properties, less distortion during the heat treatment and the like). Implementation of the rod from passing through the slot of the coupling on the stepped areas, thus covering the size of the cross section of the installation section of the rod is smaller than the width of the groove couplings, the supply of the fixing section of the rod faces, and the dimension between the gra is s less and covering the size of the faces is greater than width of the groove couplings, provide ease of Assembly, and the connection parts of the recoil mechanism. Technical solutions with the features distinguishing the claimed solution to the prototype, is not known and obvious manner from the prior art do not follow. It can be considered that the claimed technical solution has a "novelty" and "inventive step". The invention is illustrated by drawings, where: - figure 1 shows a diagram of the device VM firearms; - figure 2 is a view of the device VM; - 3 and 4 - section rod with superimposed contours of the groove of the coupling. The device VM contains a return spring 1, the step of connecting rod 2 sections: installation 3, the retainer 4 with sides 5, thrust 6 and the sleeve 7 with the groove 8 and ribs 9. Covering the amount of 10 section installation section of the rod 2 has a size less than the width of the groove 8 of the coupling 7 and the covering size 11 on sides are made larger than the width of the groove 8 of the coupling 7. The device and the other elements of VM firearms are not shown due to their being well-known. The device VM firearms is as follows. When building a VM spring 1 is mounted on the rod 2 and is compressed therein. Then, on the terminal 2 groove 8 is set clutch 7, which is brought to the installation of participants is 3, where she turns (covering $ 10 less than the width of the groove 8) to match faces with 5 surfaces of the groove 8 of the clutch 7 (rotate approximately 90°). Upon release of the spring 1, it pushes the clutch 7 to the stop 6. In this position, turn the clutch 7 and Samarasinghe hold the device face 5 of the rod 2 (covering size 11 greater than the width of the groove 8). For better orientation (alignment) on the rod 2, the sleeve 7 may be provided with annular ribs 9 limiting the axial portion 6 of the rod 2. Disassembly of the device is in the reverse sequence. Working VM in small arms depends on their design and can be considered on the example of the prototype. The device VM tested on prototypes of large-caliber guns manufactured by JSC "Zavod im. Vagetarian with positive results. 1. The return mechanism of small arms, containing the coupling groove, the step of connecting the rod with the installation, fixing and thrust areas, as well as a return spring, wherein the groove in the clutch is made of a closed-loop shape, and the rod is arranged to pass through the groove of the coupling on the stepped areas, thus covering the size of the cross section of the installation section of the rod is smaller than the width of the groove of the coupling, the locking section of the rod is made with g what she moreover, the dimension between faces less, and covers the size of the faces larger than the width of the groove of the coupling. 2. The return mechanism of small arms according to claim 1, characterized in that the coupling is provided with annular ribs.
