Further, be provided with gun needle round pin hole, fixed pinhole and percussion pinhole on the shot body, gun needle round pin hole and fixed pinhole and percussion pinhole are 45 degrees angles. When the gun needle pin hole forms an angle of 45 degrees with the fixed pin hole and the firing pin hole, the gun needle pin can never fall off, and the fixation of the gun needle and the smooth operation of the whole gun needle are ensured.

Further, the striker body is welded with the striker sleeve. The concentricity of the handle part and the needle striking tube is stabilized by welding the joint, the reliability of the product is enhanced, and the tensile strength and the anti-explosion strength of the handle part and the needle striking tube are reinforced by welding the inner wall.

Compared with the prior art, the beneficial effects of the utility model are that: (1) instantaneous airflow dispersion and sound dispersion are reduced by decibels, and plastic shell particles and ammunition carbon particles generated during nail shooting work explosion can be smoothly discharged. The included angle is designed to ensure that the unloading force in a narrow space is in an optimal state, and the sound of the airflow just absorbs the angle to form rotational flow; (2) the airflow is dispersed more uniformly, so that the sound is distributed in a circulating current, and the airflow and the sound are cut in gold to reduce the sound to the lowest decibel value; (3) carbon deposition particles in the silencing cylinder are effectively dispersed to other spaces, so that the times of dismounting and cleaning are prolonged, and the service life of the whole silencing cylinder is prolonged; (4) the main sleeve with three grooves is more humanized, unnecessary troubles caused by wrong directions are avoided during disassembly and assembly, and the tensile strength and the anti-explosion strength of the handle part and the needle striking tube are enhanced.
