The existing nail gun mainly has a nail groove for accommodating the nail body at the bottom of the machine body. The nail groove is provided with a screw that can push the nail body forward. Nail pushing unit, and the front edge of the machine body is provided with a nailing piece that can be operated manually, electrically, or pneumatically. When the nailing piece is lifted up, the nail body below is driven by the nail pushing unit and enters the firing of the nailing piece one by one. range, so when the nailing piece is released and instantly fired downwards, the nail body located below it can be driven out forcefully and nailed into the surface of the workpiece. Because it is extremely easy to use and has good efficiency, it has been widely used in recent years. used in the wood industry.

The nail gun mainly uses the elastic element to generate elastic restoring force after the nailing piece is lifted up, so when the nailing piece is released, it will generate an instant downward restoring force to hit the nail body below it powerfully. out, and complete the action of the entire nailing. Therefore, when the nail gun is not in use, if you accidentally touch the switch of the upper nail piece [such as the pressure handle of the manual nail gun], the nail body will be ejected forcefully. Sticking to the surface of the workpiece, the nail body may accidentally injure others or objects after a strong injection, causing unnecessary accidents and injuries. However, the current common protection design is to press the pressure handle on the body when it is not in use, so that It cannot drive the nailing piece up to the firing position, but because it still needs to release the pressure handle when it is working, as long as the staff does not stick the nailing gun to the surface of the workpiece, it will also cause the above-mentioned false touch action.

Touch and fire.

However, the design of the previous patent is mainly to let the hook of the pressing handle be in a normal state, and use the force of the torsion spring of the lifting lug to make the hook of the pressing handle separate from the hollow window of the punching piece, so as to prevent accidental triggering. However, if the user presses the pressure handle strongly, so that the pressing force exceeds the elastic force of the torsion spring of the lifting lug, the hook of the pressure handle can still hook the hollow window of the punch, and then fire the punch, so it cannot be completely Overcome the problem of accidentally touching the nail gun, but there is the danger of accidentally injuring people.

Based on this, the author of the present paper made an in-depth discussion on the problem that the existing nail guns cannot effectively overcome the mistaken touch of the pressure handle, and actively sought a solution based on years of experience in research and development and manufacturing in related industries. Through research and experimentation, a nail gun with safety protection has finally been successfully developed, and the nail plate cannot strike the nail body when the nail gun is not attached to the surface of the workpiece, so as to improve the safety of the nail gun. sex.
