Description

Nail shooter for narrow space

Technical Field

The utility model relates to a mechanical anchoring technical field particularly, relates to a ail shooter for narrow space.

Background

The nail shooter is a tool for driving a shooting nail into a building body by using gunpowder gas generated by launching a blank cartridge as power. The length of an axial nail shooter on the market at present generally exceeds 300mm, the nail shooter cannot be unfolded under the influence of overlong size factors of the nail shooter in a narrow space (such as a small-size channel, a ceiling sunken area, an existing narrow space of a bearing structure and the like), so that the cable support in a cable trench can be fixed only by manual knocking, the laying speed of the cable support in the cable trench is greatly reduced, the efficiency is reduced, and the labor cost is increased. Therefore, it is very important and urgent to develop a short axial nail shooter.

However, axial nailers typically consist of a housing, a cartridge extension chamber, an ejection mechanism, and a handle. The conventional axial nail shooter springs are distributed horizontally on the striking pin shaft, and the spring length cannot be shortened because of the limitation of the minimum excitation stroke and the ejection stroke, and the distribution of the springs directly causes the nail shooter to present a slender characteristic. The handle of the traditional axial nail shooter is longer, and the handle structure has no other functions except for human-machine consideration in the operation; the telescopic space of the traditional axial nail shooter bullet filling telescopic cavity comprises a nail shooting bullet rubber shell and a nail shooting length; when the firing pin of the traditional axial nail shooter is pre-pressed, the rear end of the shell of the nail shooter is provided with a space for avoiding the pre-pressed state of the firing pin. The traditional axial nail shooter firing pin is reset by a reset spring, and the length and the elasticity of the reset spring have strict requirements. Therefore, the conventional axial nailer structure cannot be shortened directly, and it cannot be used directly in a narrow space.

Therefore, the inventor designs a nail shooter for narrow space.
