Detailed implementation manners

[0030] The following combines with the drawings to describe in detail a specific implementation manner of the present utility model. However, it should be understood that the protection scope of the present utility model is not limited by the specific implementation manner.

[0031] As Figures 1 to 6 shown, an axial nail shooter provided by an embodiment of the present utility model includes a firing pin firing structure (hammer 1, main sleeve 2, firing spring 3, firing pin 4, pin shaft 5, and hammer sleeve 6), a firing pin sleeve 17, a barrel 18, a first return spring 21, an outer sleeve 23, a second return spring 24, a compression sleeve 25, and a power adjustment sleeve 26;

[0032] Among them, the firing pin 4 is installed on the hammer 1;

[0033] In some embodiments, the firing pin 4 is installed on the hammer 1 by a detachable structure;

[0034] The main sleeve 2 is sleeved on the hammer 1, the firing spring 3 is assembled in the main sleeve 2, the hammer 1 has a stepped portion, and when the nail shooter stores energy, the firing spring 3 abuts against the stepped surface of the stepped portion;

[0035] The pin shaft 5 is arranged on the hammer 1, and both ends of the pin shaft 5 are located outside the hammer 1;

[0036] In some embodiments, a pin hole cooperating with the pin shaft 5 is formed in the hammer 1, and the pin shaft 5 is located in the pin hole, so as to facilitate the removal of the pin shaft 5;

[0037] The main sleeve 2 and the hammer sleeve 6 are fixed circumferentially and slidably matched axially. Specifically, a slide groove 14 is formed in the main sleeve 2, and a slide block 13 cooperating with the slide groove is arranged on the hammer sleeve 6;

[0038] The hammer sleeve 6 is sleeved on the hammer 1, and a part of the hammer sleeve 6 is also sleeved on the main sleeve 2. A first through groove 7 and a second through groove 8 for accommodating the pin shaft 5 are respectively formed on the hammer sleeve 6 and the main sleeve 2, that is, the end of the pin shaft 5 passes through the second through groove 8 and the first through groove 7. The number of the first through groove 7 and the second through groove 8 is two each, and the two first through grooves 7 are symmetrically distributed, and the two second through grooves 8 are symmetrically distributed;

[0039] Among them, the first through groove 7 includes a relief groove 9 extending along the axial direction of the hammer sleeve 6 and a limit groove 10 communicating with the relief groove 9 in the circumferential direction; the second through groove 8 extends along the axial direction of the main sleeve 2, and the second through groove 8 has a guiding section 11;

[0040] During the firing and energy storage process, the pin shaft 5 abuts against the guiding section 11 and can move from the limit groove 10 to the relief groove 9 under the guidance of the guiding section 11;

[0041] The second through groove 8 has an energy storage end 15 and a firing end 16. The energy storage end 15 and the relief groove 9 are on the same straight line. The firing end 16 has a guiding inclined surface 12. During the firing process, the pin shaft 5 abuts against the guiding inclined surface 12 and moves from the relief groove 9 to the limit groove 10 under the guidance of the guiding inclined surface 12, that is, to return the pin shaft 5 to the position before the nail gun is charged, so as to realize the automatic reset of the firing structure of the nail gun;

[0042] In some embodiments, the two first through grooves 7 are axially symmetrically distributed, and the two second through grooves 8 are also axially symmetrically distributed. In this case, during the firing and energy storage process of the nail gun, when the pin shaft 5 moves from the limit groove 10 to the relief groove 9, the hammer 1 will move radially, resulting in its deviation from the center of the nail gun, and the structures such as the firing pin sleeve 17 need to be adjusted adaptively to cooperate with the deviated hammer 1;

[0043] Therefore, in this embodiment, the two first through grooves 7 are centrosymmetrically distributed, and the two second through grooves 8 are also centrosymmetrically distributed. In this case, the pin shaft 5 is in the Figure 3 shown state. During the firing and energy storage process of the nail gun, when the pin shaft 5 moves from the limit groove 10 to the relief groove 9, the hammer 1 will rotate by a certain angle and will not deviate from the center of the nail gun;

[0044] The barrel 18 includes a sleeve 19 and a firing pin sleeve mounting seat 20. A first return spring 21 is installed in the sleeve 19. The sleeve 19 is threadedly connected to the firing pin sleeve mounting seat 20. A boss 22 is provided in the sleeve 19. The boss 22 and the firing pin sleeve mounting seat 20 respectively abut against the two ends of the hammer sleeve 6. The firing pin sleeve 17 is installed on the firing pin sleeve mounting seat 20, so as to realize the synchronous movement of the firing pin sleeve 17 and the hammer sleeve 6,

[0045] The outer sleeve 23 is sleeved on the barrel 18; a second return spring 24 is installed in the outer sleeve 23. The end of the outer sleeve 23 is threadedly connected with a compression sleeve 25, and the compression sleeve 25 is threadedly connected with a power adjustment sleeve 26 located in the outer sleeve 23;

[0046] In addition, as Figure 1 shown, slag discharge holes are provided on the outer sleeve 23. Through the above design, an independent space is formed inside the outer sleeve 23, reducing the adverse effects of ash slag on other structures. In addition, by screwing down the pressing sleeve 25, the ash slag inside the outer sleeve 23 can be discharged, which is convenient for cleaning.
