Pneumatic nail gun capable of adjusting nailing depth

Abstract

The invention discloses a pneumatic nail gun capable of adjusting nailing depth. The gun comprises a gun head, a gun body, a cartridge holder device, a safety frame arranged on the gun head, an adjusting mechanism and a trigger device; the adjusting mechanism comprises a positioning pin and an adjusting screw rod, wherein the adjusting screw rod is located at the upper end of the positioning pin,and the bottom of the adjusting screw rod abuts against the upper end of the positioning pin; the adjusting screw rod comprises a rod part and a head part, wherein an adjusting wheel is fixed on the rod part, a pressure spring is arranged between the adjusting wheel and the gun body, and the pressure spring annularly sleeves the rod part; and a limiting seat corresponding to the adjusting wheel isarranged on the gun head, strip-shaped protrusions extending towards the direction of the adjusting wheel are arranged on the limiting seat, a plurality of strip-shaped grooves matched with the strip-shaped protrusions are evenly distributed in the outer wall of the adjusting wheel, and the strip-shaped protrusions are clamped in the strip-shaped grooves. According to the gun, the adjusting screwrod can be prevented from moving in the using process, and the distance between a muzzle and the safety frame can be accurately controlled, so that the situation that the nailing depth deviates due to rotation of the adjusting screw rod in the using process is avoided.

Description

technical field [0001] The invention relates to an air nail gun, in particular to an air nail gun with adjustable nailing depth. Background technique [0002] Pneumatic nail gun is also called pneumatic nailing machine. The air nail gun uses the air pressure generated by the air pump (air compressor), and the high-pressure gas drives the striker in the nail gun cylinder to perform hammering movement, and nails the nails in the nail clip into the object. Or shoot out the row of nails. [0003] During the nailing operation, the actual use environment often requires different nailing depths. The existing pneumatic nail gun adjusts the adjustment screw to adjust the distance between the end of the safety frame and the muzzle of the gun head to achieve the adjustment of the nailing depth. , but the pneumatic gun will vibrate during use, and the impact force generated by the vibration will drive the adjustment screw to rotate, causing the distance between the end of the safety fr...

[0003] During the nailing operation, the actual use environment often requires different nailing depths. The existing pneumatic nail gun adjusts the adjustment screw to adjust the distance between the end of the safety frame and the muzzle of the gun head to achieve the adjustment of the nailing depth. , but the pneumatic gun will vibrate during use, and the impact force generated by the vibration will drive the adjustment screw to rotate, causing the distance between the end of the safety frame and the muzzle of the gun head to shift, resulting in a change in the nailing depth, which cannot achieve the desired effect , need to be constantly adjusted manually, which is time-consuming and labor-intensive
