The invention relates to locking mechanisms for small arms. The closest analogue (prototype) is the shutter with a detachable handle hunting rifle "Huntsman" Vyatka-Polyansky machine-building plant "Molot" (see the journal "World of weaponry, No. 4, 2006, p.38-45), containing the body of the bolt, detachable arm, a thrust bearing, the drummer, fighting the spring. Fixing the detachable arm is thrust bushing guide mainspring drummer and using a mainspring, which is U-shaped groove on the end face of the cylindrical part of the handle. The disadvantages of the known constructions are: insufficient rigidity of a detachable handle because of the presence of a U-shaped groove on the end of the handle; - lack of reliability of the gate during operation because of the possibility of separation of the handle from the bolt by reducing the rigidity of the mainspring during operation; the difficulty of disassembly and Assembly for maintenance. The aim of the invention is the creation of a shutter, providing the technical result consists in increasing the rigidity of the detachable arm and reliability of the gate during operation, disassembly and Assembly for maintenance. This technical result in the bolt firearms with a detachable handle, containing the body of the bolt, coupling, otherswould, is achieved by the fact that the clutch is made of at least one projection, and the detachable handle is shaped hole for the passage of the coupling protrusion, and the protrusion is located behind the figure bore and cooperates with the chamfer is performed on a detachable handle. It is advisable that the coupling includes a spring-loaded latch that interacts with the recess made in the body of the shutter and providing mutual orientation of the coupling protrusion and the keyholes detachable arm that is not the same in open and closed position of the shutter. The invention is illustrated by drawings, which shows: - figure 1 - the shutter with a detachable handle, General view; - figure 2 - body shutter, General view; - figure 3 - coupler, General view; - figure 4 is detachable handle, General view; - 5 - section a-a in figure 1. The shutter Assembly is composed of a body of the shutter 1, a clutch 2, a detachable arm 3. The body of the shutter 1 is a part of complex shape with a hole 4 for accommodating a detachable handle 3 and 5 hole for placement of the coupling 2. The clutch 2 is a detail of stepped form. The middle step 6 is executed in the form of a cylinder the same diameter with the diameter of the hole 5 of the body of the shutter 1, and is intended for centering the clutch 2 relative to the body of the shutter 1. Step 7 of smaller diameter is made in widetilde. Stage 7 is made of at least one protrusion 8 (in the drawings shows an embodiment with two projections 8). In the clutch 2 has a hole 9 in which is located the latch 10 and the spring 11 of the retainer 10. On the body of the shutter 1 has a recess 12, which sets the latch 10. Part of the detachable arm 3, which is included in the body of the shutter 1 is a round rod of the same diameter with the diameter of the hole 4 in the body of the shutter 1. On the part of the detachable arm 3, which is included in the body of the shutter 1, performed shaped opening 13 for the passage of the protrusion 8 of the clutch 2 when the Assembly. Also part of the detachable arm 3, which is included in the body of the shutter 1, the chamfer 14, which abuts against the protrusion 8 of the coupling 2. The shutter Assembly is as follows. In the opening 4 of the body of the bolt 1 is inserted detachable arm 3. Further, combining the projections 8 of the coupling 2 with shaped hole 13 in a detachable handle 3 into the hole 5 of the body of the bolt 1 is inserted into the sleeve 2 and is pushed forward until it stops in the body of the shutter 1. While the projections 8 of the clutch 2 will be located behind the detachable arm 3. To guide coupling 2 relative to the body of the shutter 1 to rotate the sleeve 2 around the longitudinal axis to align the retainer 10 with a recess 12 in the body of the shutter 1. While the projections 8 of the clutch 2 will come into contact with the chamfer 14 detachable arm 3 and to prevent the retraction of the coupling 2 of the t is La shutter 1, and step 7 will prevent removing detachable arm 3 from the body of the shutter 1. Thus, the proposed design of the slide firearms with a detachable handle allows you to increase the rigidity of the outer arm and the reliability of the shutter during operation, to simplify the disassembly and Assembly for maintenance. 1. The shutter firearms with a detachable handle, containing the body of the stopper, clutch, detachable handle, characterized in that the clutch is made of at least one projection, and the detachable handle is shaped hole for the passage of the coupling protrusion, and the protrusion is located behind the figure bore and cooperates with the chamfer is performed on a detachable handle. 2. The shutter according to claim 1, wherein the coupling includes a spring-loaded latch that interacts with the recess made in the body of the shutter and providing mutual orientation of the coupling protrusion and the keyholes detachable arm that is not the same in open and closed position of the shutter.
