In this embodiment, the launching tube 2 is provided with a plurality of power adjusting cavities 201 communicated with the interior thereof, and the plurality of power adjusting cavities 201 are detachably connected with pressure adjusting bolts 202.

In this embodiment, the tail cap 7 is screwed with the outer casing 1.

In this embodiment, the outer side of the launching tube 2 is sleeved with a noise elimination sleeve 3, and the noise elimination sleeve 3 is connected with a connection sleeve 4.

This ail shooter needs assemble each part before the percussion, and the equipment step is as follows:

(1) assembling a percussion assembly: firstly, a safety spring 801 and a safety pin 802 are arranged in a counterbore 603 of the needle striking body 601 component, then the needle striking body 601 component is arranged in a needle striking base 501, and a positioning pin 11 is inserted in a positioning chute 504.

(2) The percussion assembly is arranged in the connecting sleeve 4, the shell-withdrawing spring 9 is sleeved on the connecting sleeve 4 and is pressed into the outer sleeve body 1, the percussion assembly is fixed by the positioning pin 11 and is arranged in the percussion spring 10, finally the screw thread is connected with the tail cover 7, and the handle 11 is sleeved on the tail cover 7.

(3) The transmitting tube 2 is sleeved on the firing pin sleeve 502 and sleeved in the connecting sleeve 4, and the silencing sleeve 3 is sleeved on the connecting sleeve 4 in a threaded manner and is pressed tightly.

When the nail shooter is in an unfired state, the firing spring 10 and the shell withdrawing spring 9 are both in an uncompressed state, the coupling sleeve 4 and the outer sleeve 1 are in a separated state, and the firing pin body assembly 6 and the tail cover 7 are also in a separated state. In this state, the arming spring 801 is also in an uncompressed state, and the opposing arming pin 802 is ejected out of the counterbore 603 and extends outside the striker post 501. In this state, the safety pin 802 locks the striker base 501 and the striker body 601 together, i.e., the safety is not released, and thus, the striker cannot be fired.

When the nail shooter needs to be fired, the integral bomb is arranged in the launching tube 2, the launching tube 2 is propped against the base body, and a force towards the direction of the base body is manually applied to the nail shooter. The outer sleeve 1 slides relatively with the coupling sleeve 4 and moves in the direction of the firing tube 2, the return spring 9 being compressed. Simultaneously, the striker base 501 is pushed, driving the striker body 601 to move towards the tail cover 7, and the firing spring 10 is compressed. During the movement of the striker body 601, the safety pin 802 gradually contacts with the triggering conical surface 701, so that a downward thrust is generated under the action of the triggering conical surface 701, the safety pin 802 is compressed and moves towards the interior of the counter bore 603, and the safety pin 802 gradually disengages from the safety sliding groove 503. When the safety pin 802 is completely disengaged from the safety slide groove 503, the striker body 601 is relieved of the safety. The pressure of the firing spring 10 is released, and the pushing force of the firing spring 10 pushes the striker body 601 to displace, generating a pushing force towards the substrate, thereby driving the striker 602 to displace towards the substrate. The tip of firing pin 602 pierces violently into the projectile. The detonation of the integrated bomb releases huge heat, the heat is converted into mechanical energy under the action of the launching tube 2, and an integrated nail in the integrated bomb is hit into the base body. In the process of firing, the positioning pin 11 moves in the clamping ring 101; meanwhile, the positioning pin 12 is connected with the striker body 601, the striker base 501 and the outer sleeve 1, and the three move relatively, so that the movement of the striker body 601 and the striker base 501 can be positioned in the moving process, the accuracy of the displacement is ensured, and the displacement of each part is prevented from deviating due to no positioning, thereby influencing the effect of percussion. After the percussion is finished, the shell withdrawing spring 9 drives the connecting sleeve 4 to displace towards one end far away from the outer sleeve 1, so that the connecting sleeve 4 is taken out of the outer sleeve 1.

The outer sleeve body 1 is provided with at least one heat dissipation and dust removal hole 102, and heat dissipation and dust removal can be performed after firing; the launching tube 2 is provided with a power adjusting cavity 201 and pressure adjusting bolts 202, and the pressure inside the launching tube 2 can be adjusted by setting the number of the pressure adjusting bolts 202, so that the power of the percussion is adjusted. Through adjusting the length of launching tube 2, can stretch into the gap with it, conveniently shoot the nail operation.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
