Description

Technical Field

[0001] The utility model relates to the technical field of nail fixing devices, in particular to a pneumatic slag removal type nail fixing device. Background Art

[0002] With the development of nail fixing technology, the various advantages of nail fixing make its application more and more extensive.

[0003] When the nail fixer is in use, the firing pin moves forward rapidly in the firing pin sleeve, and its tip part hits the tail of the integrated nail, causing the integrated nail to explode. The generated gas pushes the nail into the front end base quickly, completing the nail shooting process.

[0004] When using the existing nail fixing device, the nail bullet is loaded into the nail tube, the movable sleeve and the firing pin sleeve are moved to the rear end, and the firing pin is fired out by unlocking the compression potential energy of the firing spring, thereby firing the nail bullet into the wall. However, there are the following problems in the production and use of such nail fixing devices:

[0005] (1) At present, there is a positioning step at the rear end of the nail tube. When the residue in the silencer sleeve is full, the nail tube cannot be removed, and the disassembly process is very difficult or even impossible. The consequence is that when the nail fixer is maintained after a period of use, the launch tube cannot be removed, and the entire front silencer assembly has to be discarded, which is a waste of resources.

[0006] (2) At present, the multiple adjustment holes in the nail tube need to be tapped one by one, and the screws need to be screwed one by one, which is easy to slip, difficult to process, and time-consuming. If the working time is too long, the screws will get stuck and cannot be removed, resulting in waste.

[0007] Therefore, the utility model proposes a pneumatic slag removal type nail fixing device. Utility Model Content

[0008] Technical issues solved

[0009] The utility model aims to make up for the deficiencies of the prior art and provides a pneumatic slag removal type nail fixing device.

[0010] Technical Solution

[0011] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pneumatic slag removal type nail fixing device, comprising a silencer sleeve, a launching tube and a silencer sleeve cover, wherein a silencer sleeve is arranged outside the launching tube, a silencer sleeve cover is arranged outside the silencer sleeve, and the launching tube is provided with a cavity; a silencer cavity is arranged between the launching tube and the silencer sleeve, and the characteristic is that a slag removal port is arranged between the launching tube and the silencer sleeve.

[0012] Preferably, the launching tube is flush with, protrudes from, or is sunken into the slag discharge port.

[0013] Preferably, the slag discharge port has a slope, and the slag discharge port is a 360° circular slag discharge port.

[0014] Preferably, the front end of the launch tube has a compression surface and a force-bearing surface, the rear end of the launch tube is suspended and has no force-bearing surface, the cavity and the silencer cavity are connected through an adjustment hole, a detachable adjustment piece is connected in the adjustment hole, and a compression surface is provided below the force-bearing surface.

[0015] Beneficial effects:

[0016] Compared with the prior art, the pneumatic slag removal type nail fixing device has the following beneficial effects:

[0017] Under the premise of not changing the working mode and effect of the original equipment, the utility model has a slag discharge port between the launch tube and the silencer sleeve. The power generated after the nail is fired will squeeze the plastic shell residue in the silencer sleeve, and squeeze the plastic shell residue into a crushed state. Through the slag discharge port, 360° automatic slag discharge, exhaust and heat dissipation can be achieved. The slag discharge effect is more significant than the granular slag discharge effect in the prior art. It can effectively prevent slag from accumulating in the nail fixer, and quickly dissipate heat to avoid damage to components due to excessive temperature. It can prevent the launch tube and other components from overheating after firing, protect the launch tube, and overcome the problem that the slag cannot be discharged after the existing nail fixer is fired, and the operator cannot hold it due to excessive heat. It is convenient for operation and improves the safety of the utility model. BRIEF DESCRIPTION OF THE DRAWINGS
