And a bolt lock groove 1001 is arranged at the lower part of the bolt 10 and corresponds to the position of the bolt lock 1, wherein the bolt lock tooth 108 arranged on the bolt lock 1 is clamped into the bolt lock groove 1001 when the bolt lock 1 is in the lock state, and the bolt 10 is locked so as to prevent the bolt 10 from being pulled backwards.
The sear spring 3 and the firing lever spring 6 directly act on the sear 2, the firing lever 5 and the sear spring seat 4, so that the sear 2 and the upper end of the firing lever 5 are overturned backwards and then reset timely, the sear spring seat 4 has a trend of overturned backwards, and indirectly act on the safety 1 through the sear spring seat 4, so that the 'M' -shaped safety positioning groove 402 arranged at the rear part of the sear spring seat 4 is tightly buckled with the safety positioning teeth 104 arranged on the safety 1, and the safety 1 is reliably positioned.
When the pistol is switched from a non-safety state (a state that the pistol is opened and can be shot normally) to a safety state (a state that the pistol is closed and can not be shot), the safety spanner 101 is pushed to enable the safety 1 to turn backwards, and the safety positioning teeth 104 arranged on the safety 1 slide into the safety positioning grooves 40202 from the non-safety positioning grooves 40201 of the M-shaped safety positioning grooves 402 arranged on the sear spring seat 4, so that the switching from the non-safety state to the safety state is completed; when the safety state is switched to the non-safety state, the safety spanner 101 is shifted to enable the safety 1 to turn forwards, and the safety positioning teeth 104 arranged on the safety 1 slide into the non-safety state positioning grooves 40201 from the safety state positioning grooves 40202 of the M-shaped safety positioning grooves 402 arranged on the sear spring seat 4, so that the safety state is switched to the non-safety state.
When the safety 1 is in the safety state, the trigger 9 of the pistol is triggered, the sear safety teeth 202 at the rear part of the sear 2 and the firing lever safety teeth 502 at the rear part of the firing lever 5 are limited by the cylindrical surface of the thick shaft of the safety shaft 102 on the safety 1, so that the firing lever 5 cannot be turned backwards under the action of the pull rod 8 to lift the firing pin safety piece 12 so as to release the firing pin safety and push the sear 2 to be turned backwards so as to release the firing pin 11, the sear 2 cannot be turned backwards by itself to release the firing pin 11, and meanwhile, the gun safety teeth 108 arranged on the safety 1 are clamped into the gun safety grooves 1001 arranged on the gun 10 to lock the gun 10, so that the gun 10, the sear 2 and the firing lever 5 cannot be stably restrained and limited, the firing pin 11 cannot be stably hooked by the sear 2 so as to release and fire the firing rod 11 cannot be released and the trigger 9 which acts in association with the sear teeth is also limited and the trigger 9.
In particular, when the pistol is in the "half-safe" state, i.e., the bumper grip 101 is in the position between the open and closed bumpers, the bumper positioning tip 10401 is pushed against the middle tip 40203 between the non-safe positioning groove 40201 and the safe positioning groove 40202 in the "M" -shaped bumper positioning groove 402, and is in an extremely unstable static equilibrium state under the action of the sear spring 3 and the firing lever spring 6, and when the trigger 9 is pulled, the firing lever 5 is turned backward, the firing lever bumper tooth 502 at the rear of the firing lever 5 presses against the bottom of the firing lever pressing groove 106 provided on the bumper shaft 102, and applies a moment to the bumper shaft 102, which turns the bumper 1 backward, thereby breaking the extremely unstable "half-safe" state, and causing the bumper 1 to jump to the safe state by itself. According to the relevant knowledge of the mechanical and static balance and the practical experience of the sample machine of the manual safety mechanism, the state of 'half safety' is only found under 'searching' deliberately and very deliberately by a user, and the difficulty is very high. Therefore, the ingenious structural design of the invention ensures the high safety of the manual safety mechanism by reducing the occurrence probability of the 'half-safety' state and reliably releasing the 'half-safety' state.
When the manual safety mechanism is assembled, firstly, a pre-assembled sear part (a sear part assembling method is referred to a method for assembling a handgun sear part) is installed into a sear shaft hole 704 of a transmitter base 7 through the sear shaft, then a one-side safety spanner 101 of a safety shaft 1 penetrates through a safety spanner yielding groove 701 of the transmitter base 7, the safety shaft 102 is positioned below the sear part, the safety shaft 1 is rotated to enable the bottom surface of an orientation installation groove 107 on the safety shaft 102 to be in a vertical state and parallel to an orientation installation groove 702 on the transmitter base 7, then the safety shaft 1 is vertically moved upwards to be installed into the safety shaft hole 703 through the orientation installation groove 702, finally, the safety shaft 1 is turned forwards, a small plane (in an inclined state at the moment) at the front part of an insurance positioning tooth 104 on the safety shaft 102 automatically jacks up the rear part of the sear spring base 4 to enable the insurance positioning tooth 104 to slide into the M-shaped insurance positioning groove 402, and thus the assembly of the manual safety mechanism is completed; when the manual safety mechanism is disassembled, the front part of the sear spring seat 4 is pressed to enable the sear spring seat 4 to turn forwards, then the safety positioning teeth 104 are rotated out of the M-shaped safety positioning groove 402 by rotating the safety 1 backwards, the bottom surface of the directional mounting groove 107 on the safety shaft 102 is in a vertical state, the safety 1 is moved downwards to move the safety 1 from the safety shaft hole 703 into the safety spanner yielding groove 701, and finally the safety 1 and the sear part are taken down from the transmitter seat 7, so that the manual safety mechanism is disassembled.
Finally, it is noted that the above-mentioned preferred embodiments are only intended to illustrate rather than limit the invention, and that, although the invention has been described in detail by means of the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
