firearm firing unit

Abstract

The invention relates to a percussion unit of a gun. A driving hammer is clamped by a front fastening block before a trigger is pulled, and the driving hammer drives a main rod to move backwards and allows a rear fastening block and the front fastening block which are elastically abutted against the main rod to swing backwards along with the main rod when the trigger is pulled. When the trigger is slightly pulled and the main rod moves backwards at a short distance, the front fastening block swings backwards to allow the driving hammer to be released and swing backwards and hit forwards, and single bullet firing is achieved. When the trigger is pulled heavily and the main rod moves backwards at a long distance, the driving hammer is not clamped by the front fastening block when swinging backwards, the driving hammer is clamped by the rear fastening block when a bolt move backwards and the driving hammer presses backwards, a connecting rod component is driven to move forwards to pull the rear fastening block forwards when the bolt moves forwards the driving hammer is then released to swing backwards and hit forwards, and running fire is achieved by repeating the operation accordingly. By the percussion unit, single-bullet firing and running fire can be achieved by slightly or heavily pulling the trigger, and structural simplification and operation convenience are achieved.

Description

technical field [0001] The present invention refers to a firing unit of a firearm, especially a firing unit of a firearm that can achieve a single-shot or continuous-fire firing mode only by lightly or heavily pulling the trigger. Background technique [0002] General large-scale firearms usually have a single-shot or multi-burst firing selection function, such as China Taiwan Patent No. case. [0003] The above-mentioned prior patent case discloses that the fire control structure is at least composed of a gunlock, a hammer, a trigger, a hammer hook, a burst control lever, and a switch. There is a shaft inside the body, and the shaft is equipped with a suitable slot for the operation of the trigger. It cooperates with the operation of the hammer hook, the burst control lever, the added ratchet, and the ratchet hook to achieve single-shot or multi-shot of the gun. firing operation. [0004] Yet above-mentioned existing single shot or continuous firing switching still must ...

AI Technical Summary

Problems solved by technology

[0008] Based on the above, it can be seen that the technical problem to be solved by the present invention is that when switching between single-shot and continuous-fire in the prior art, it is still necessary to additionally set and operate the paddle, adjustment block or wheel, which causes inconvenience in operation. And increase the defect of structural complexity, provide an effective improvement of technical structure
