Description

Technical Field

[0001] The utility model relates to the technical field of ceiling nail fixing devices, in particular to a spring-connected firing pin tube. Background Art

[0002] A ceiling nailer is a modern nail-shooting fastening technology product that can fire nails. It belongs to direct consolidation technology and is an essential hand tool for carpentry, building construction, etc. When the nailer is working, it uses the gunpowder gas generated by firing blank bullets as power to drive nails into the building body.

[0003] The firing mechanism of the existing top nailer mainly includes a firing pin tube and a firing pin seat and firing pin arranged in the firing pin tube. For example, the application number 2021214123727 applied for by our company for research and development discloses a new type of adjustable pressure ceiling fixture, and the application number 2021214123515 discloses a new type of automatic slag discharge mini ceiling fixture. The firing pin tubes of the above structures all adopt an integrated structure. During use, it is found that the needle sleeve part of the firing pin tube is easier to be damaged. However, whether the needle sleeve part of the firing pin tube or the seat sleeve part of the firing pin tube is damaged, the entire firing pin tube needs to be replaced, which has a high cost of use. In addition, due to the overall design, when replacing the firing pin tube, the ceiling fixture needs to be disassembled and assembled as a whole, and replacement is also very troublesome.
