The firing device is connected with sear one end after the compression, pulls the trigger, is connected with the sear other end and drives the sear to rotate when the trigger rotates, and the sear separates with the firing device, and the release of firing device triggers the bullet, and the trigger returns the normal position under the effect of trigger torsional spring, sear, and the firing device draws back to the compression state and makes it be connected with the sear, accomplishes and goes up the thorax.
The trigger device comprises a piston and a fixedly arranged hanging machine roller pin, a limit groove in matched connection with the hanging machine roller pin is arranged on the piston, and compression and release of a piston spring are achieved through connection and separation of the hanging machine roller pin and a stopper. When the piston moves to a compression state, the hanging machine roller pin is buckled in the limiting groove, the stop iron is reset through the torsion spring and is abutted against the hanging machine roller pin, the interaction force keeps balance, the piston is in the compression state, preparation is made for percussion, when the trigger drives the stop iron to rotate, the stop iron is separated from the hanging machine roller pin, the abutting force of the stop iron on the hanging machine roller pin is eliminated, the piston compresses air under the action of the piston spring, and the bullet is shot.
Further, a trigger screw is arranged on the trigger and is connected with the iron block in a matched mode. The trigger rotates to contact with the sear to realize a first stroke, and rotates to contact with the trigger screw to realize a second stroke and trigger.
Further the trigger screw is adjustable in position on the trigger. The contact area of the stop iron and the trigger screw is adjusted by adjusting the trigger screw, so that the second stroke of quick percussion is realized.
And further, a choke screw is connected to the choke, and the distance between the trigger and the choke matching connecting end is changed through the adjustment of the choke screw. The distance between the contact of the sear and the trigger connecting end is adjusted by adjusting the position of the sear and the trigger connecting end to realize the adjustment of the first stroke.
To sum up, the utility model provides a simple structure, convenient operation can conveniently adjust the firing mechanism of the first stroke and the second stroke of firing.
