They are mainly divided into traditional fasteners and portable fasteners.

[0003] Traditional fasteners are designed with separate nails and blank cartridges. When installing, first load the blank cartridge into the nail gun, then load the nail into the barrel, press the barrel to trigger, and eject the blank cartridge. Blank cartridges are made of metal, are expensive, and are cumbersome and inconvenient to load, and have low work efficiency, and have gradually been eliminated by the market.

[0004] At present, portable fasteners are mainly used, that is, nail gun integrated nail bullets, gunpowder is encapsulated in the tail of the nail through a plastic capsule, the gunpowder is fired by firing the firing pin, the gunpowder explodes in the gun chamber to push the nail, and the nail is driven into the matrix by a strong shock wave. Now portable fasteners have become the mainstream of the market and are widely used in construction, decoration, exploration and outdoor applications. However, the existing fasteners are inconvenient to activate and reset during use, and some structures are severely worn during use. Utility Model Content

During use, the limiting rivet 11 slides up and down in the limiting groove 31, and the limiting rivet 11 can be used to control the movement distance of the firing slide 12, and a locking groove 34 is also provided on the rear end side of the firing locking sleeve 3, and a firing locking sleeve notch 33 is provided at the end of the locking groove 34, and the end of the firing locking sleeve notch 33 is respectively set to an inclined surface of 60°, 70° or 75°. During implementation, the ends of the firing locking sleeve notch 33 are respectively set to inclined surfaces of different angles, so that different inclined surfaces can be satisfied during use to achieve effective fixation during the excitation and pressing process.

[0026] The usage process of this embodiment is:

[0027] First, the integrated firing bullet is loaded into the needle-loading sleeve 1, and the operator holds the trigger and aims it at the object to be fastened;

[0028] The operator presses the object to be fastened and presses the gun handle 10, and the firing locking sleeve 3 connected to the locking pin, the firing slide 12 and the firing locking housing 6 are relatively displaced so that the firing spring 9 accumulates force;

[0029] When the locking pin moves to the reverse slope of the firing locking sleeve notch 33 at the rear end of the firing locking sleeve 3, since the firing locking sleeve 3 is limited by the rivet pin 11 and cannot rotate but can only move forward and backward, the locking pin 14 will be lifted upward under the action of the slope;

[0030] When the locking pin 14 is lifted to the locking slot 34 of the firing locking sleeve 3, the locking pin 14 completes the unlocking action;

[0031] The elastic potential energy stored in the firing spring 9 acts on the firing slide 12, and the firing slide 12 drives the firing pin 5 to move forward together, and the firing pin 5 hits the gunpowder at the tail of the integrated firing bullet. The energy generated by the explosion of the gunpowder drives the nail into the matrix to be firmly locked.

[0032] The shell ejection spring 8 pushes the silencer sleeve to move forward, and the firing locking sleeve 3 connected thereto moves forward at the same time, and the firing locking sleeve 3 and the firing locking housing 6 are relatively displaced, and the locking pin 14 is blocked by the front reverse bevel of the firing locking housing 6. Since the firing locking sleeve 3 is locked by the rivet pin and cannot rotate, the reverse bevel acts on the locking pin and generates a downward force;

[0033] When the firing locking sleeve 3 and the firing locking housing 6 move to the opening groove 33, the locking pin 14 moves downward under the action of the reverse slope of the locking slot 34 in the firing locking housing 3 until it is locked in place;

[0034] After the locking is completed, the operator holds the gun body 10 with one hand and the ejection sleeve 2 with the other hand, and pulls the ejection sleeve 2 backward along the straight direction of the gun body, the locking pin 14 locks the firing locking sleeve 3, and the firing spring 9 acts on the firing slide to prevent the firing locking sleeve 3 from moving backward. The ejection sleeve connected to the nailing barrel 1 and the firing locking sleeve 3 move relative to each other, so that the cartridge case is pushed out by the firing locking sleeve 3 to complete the ejection.

[0035] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
