Abstract
Description
Technical Field
[0001] The invention relates to an air nail gun, in particular to an air nail gun with adjustable nailing depth. Background Art
[0002] Pneumatic nail guns are also called pneumatic nailing machines. Pneumatic nail guns use the air pressure generated by an air pump (air compressor). The high-pressure gas drives the firing pin in the nail gun cylinder to do hammering motion, nailing the nails in the nail clip into the object or shooting the nails out.
[0003] During nailing operations, the actual use environment often requires different nailing depths. The existing pneumatic nail gun adjusts the distance between the end of the safety frame and the muzzle of the gun head by adjusting the adjusting screw to achieve the adjustment of the nailing depth. However, the pneumatic gun will vibrate during use. The impact force generated by the vibration drives the adjusting 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 fails to achieve the expected effect and requires continuous manual adjustment, which is time-consuming and labor-intensive. Summary of the invention
[0004] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide an air nail gun with adjustable nailing depth, which can accurately control the nailing depth and prevent the nailing depth from being offset due to the rotation of the adjusting screw during use.
[0005] The present invention is completed by adopting the following technical scheme: an air nail gun with adjustable nailing depth, comprising a gun head, a gun body, a clip device, a safety frame arranged on the gun head, an adjustment mechanism and a trigger device, the end of the safety frame has a round tube portion, the round tube portion is sleeved at the muzzle of the gun head, the adjustment mechanism comprises a positioning pin and an adjusting screw, the positioning pin is arranged on one side of the gun head, the adjusting screw is threadedly connected with the gun body and can be adjusted and moved up and down, the adjusting screw is located at the upper end of the positioning pin, the bottom of the adjusting screw abuts against the upper end of the positioning pin, the adjusting screw comprises a rod portion and a head portion, an adjusting wheel is fixed on the rod portion, a compression spring is arranged between the adjusting wheel and the gun body, the compression spring ring is sleeved on the rod portion, a limiting seat corresponding to the adjusting wheel is arranged on the gun head, a strip protrusion extending in the direction of the adjusting wheel is arranged on the limiting seat, a plurality of strip grooves matching the strip protrusions are evenly distributed on the outer wall of the adjusting wheel, and the strip protrusions are stuck in the strip grooves.
[0006] In the present invention, the adjusting screw is first rotated, and then the distance between the circular tube portion of the safety frame and the muzzle of the gun head is slightly adjusted by positioning, so as to adjust the nailing depth of the air nail gun. The strip protrusion of the limit seat is stuck in the strip groove of the adjusting wheel, which can prevent the adjusting screw from being displaced during use, accurately control the distance between the muzzle and the safety frame, prevent the adjusting screw from rotating due to the impact force generated during the nailing process, avoid the nailing depth from shifting during use, and more accurately position without the need for frequent adjustments by the operator.
