Description

Technical Field

[0001] This utility model belongs to the field of nail gun technology, specifically referring to a nail gun with an easy-to-replace firing pin. Background Technology

[0002] A nail gun is a nail-driving device widely used in the construction industry. Its principle is to drive the impactor to nail by using compressed air or gunpowder as a power source.

[0003] Due to metal fatigue, the firing pin of existing nail guns needs to be replaced after prolonged use. The current replacement method requires workers to remove the sleeve layer by layer to remove the firing pin, and then reassemble the parts one by one. The process is too cumbersome and wastes manpower. Therefore, there is an urgent need for a nail gun that makes it easier to replace and install the firing pin to solve the above problems. Utility Model Content

[0004] The technical problem this invention aims to solve is that the existing method for replacing the firing pin of a nail gun requires workers to remove the sleeve layer by layer to take out the firing pin inside. After replacement, the parts need to be reassembled one by one, which is too cumbersome and wastes manpower.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a nail gun that facilitates the replacement and installation of firing pins, including a gun barrel, a magazine disposed on one side of the lower end of the gun barrel, a power source disposed on the other side, a handle disposed between the gun barrel and the power source, a generating housing fixedly connected to the upper end of the power source, and a side wall of the generating housing fixedly connected to the gun barrel.

[0006] The barrel has a slot, and the slot is equipped with a convenient opening and closing component. The convenient opening and closing component includes two fixing members that are hinged to both sides of the slot and arranged in a mirror shape.

[0007] The barrel cavity is provided with a firing pin housing. One end of the firing pin housing is provided with a fixing component. The fixing component includes a connector that is fixedly connected to one end of the firing pin housing for fixing the firing pin housing.

[0008] Furthermore, the convenient opening and closing assembly also includes a rectangular block fixed between two fasteners, and the fasteners and the rectangular block are connected by bolts.

[0009] Furthermore, the lower end of the rectangular block and the inner walls of the two fixing members, together with the gun barrel, form a circular groove that fits the firing pin housing.

[0010] Furthermore, a rectangular groove is provided on one side wall of the generating housing, and the fixing assembly includes two rectangular connecting blocks fixed at the upper and lower ends of the rectangular groove. The lower end of the rectangular connecting block is vertically slidably connected to an L-shaped block that cooperates with the connecting piece through a spring and a limiting rod.

[0011] Furthermore, the connector is composed of a circular part and an elliptical part with a transverse opening, and a limiting groove is provided between them to cooperate with the L-shaped block, and the L-shaped block can be pulled out from the opening.

[0012] Furthermore, the center of the connector is hollowed out.

[0013] The beneficial effects of this utility model by adopting the above structure are as follows:

[0014] 1. It is equipped with a convenient opening and closing component. By unscrewing the bolts connecting the two fixing parts and the rectangular block, the firing pin housing inside the barrel cavity can be seen, thereby simplifying the disassembly process. At the same time, the fixing parts and the rectangular block together with the barrel form a circular groove that fits the firing pin housing, so that the device can be used normally.

[0015] 2. A fixing component is provided. By twisting the connector at one end of the firing pin housing, the L-shaped block can be connected to the connector, thereby removing the firing pin housing and replacing the firing pin inside. Attached Figure Description
