Comparative anatomy of pistols
All pistols are less similar to each other.
The pistol consists of the following components:
- USM (shock-trigger mechanism),
- return mechanism,
- shop gun.
The frame is connected to the handle of the gun and the trigger guard. It is the fastening part that unites and makes the parts and mechanism one.
To the frame is attached the store fixer with a spring (this keeps the store from falling out).
The barrel is fixedly fixed to the frame stand (it is fixed with a transverse pin). On the muzzle of the trunk is the base of the fly, and the fly itself, which is fastened with a screw. Using the fixing screw of the front sight, you can change its height.
The sight consists of a base (fixed to the frame by a rivet) and a whole (fastened with a fixing screw). The target is like the fly, it can be moved to the right / left with the fixing screw. After moving to the desired position, the target and the fly are fixed with the same screw (so that they do not "jam" during the shooting).
The bolt is responsible for bringing the trigger to the combat position (platoon) and locking the barrel bore, as well as for sending / removing the cartridge from the magazine into the chamber and from the chamber.
In the gate distinguish such parts:
- a frame with a sender;
- drummer with a spring (during the shot strikes the cartridge shell);
- ejector with a spring (removes the cartridge sleeve from the chamber).
The drummer is a rod on which a bouncing spring is attached, which retracts the hammer into the bolt.
USM (shock-trigger mechanism) consists of:
- The trigger (with thrust and axle),
- fighting springs,
- release thrust,
This mechanism works in the following order. Sheptalo is designed to fix the trigger in the fighting and safety positions. Trigger hook with trigger pull shifts the whisper when pressed (unlocks USM). The trigger drives the drummer. The release trigger eliminates accidental triggering when the mechanism is incompletely brought into combat position. The battle spring is connected to the trigger. The restrictive screw adjusts the trigger stroke.
The trigger spring returns the hook to its original position after pressing.
The spring of the pull rod displaces the pull rod to the top.
The shield fixes the hook and its springs, as well as the trigger pull from the fall. Attached to the frame with a fixing screw.
The fuse limits the bottom of the sear and thus prevents the trigger from moving spontaneously.
The return mechanism returns the bolt to its original position.
The shutter closes the shutter movement backward.
The gun shop is a part for the placement of ammunition.
Some pistols have on the handle lining of wood, rubber or composite materials, they are designed for a more convenient retention of weapons and prevent it from escaping when firing. Lining is called "cheeks".
