[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] The utility model provides a firing pin seat.

[0027] In this embodiment, refer to Figure 1-4 The firing pin seat includes a firing pin seat body 1, one end of which is provided with a connecting hole 2 connected to the firing pin 17, and an outer wall of the firing pin seat body located at one end of the connecting hole 2 is provided with a pressure relief structure, and the pressure relief structure forms a pressure relief gap 3 between the firing pin seat and the inner wall of the firing pin seat cover 18.

[0028] In the above technical solution, by arranging a pressure relief structure on the outer wall of the firing pin seat body, a pressure relief gap is formed between the firing pin seat and the inner wall of the firing pin seat sleeve, thereby improving the pressure relief capacity of the nail fastener when working and reducing the resistance of the nail fastener when striking, thereby contributing to the overall working performance of the nail fastener.

[0029] Specifically, a pressure relief ring groove 4 is provided on the firing pin seat body, and the pressure relief structure extends from the firing pin seat body to the pressure relief ring groove 4.

[0030] By providing a pressure relief ring groove, the pressure relief effect can be further improved and the effect of reducing firing resistance can be further improved.

[0031] The pressure relief structure is mainly used to increase the gap between the firing pin seat and the inner wall of the firing pin seat cover, thereby increasing the air flow rate and improving the effect of pressure relief and exhaust. This is achieved by setting a notch or a groove on the outer wall of the firing pin seat, such as the following embodiments of the pressure relief structure.

[0033] The pressure relief structure is a cutting plane structure 5 on the outer wall of the firing pin seat body; there are two cutting planes, which are arranged opposite to each other on both sides of the firing pin seat body 1; and a pressure relief groove 6 extending to the connecting hole is provided on the cutting plane.

[0034] like Figure 1-4As shown, the pressure relief structure adopts a cut plane structure to form a pressure relief gap between the firing pin seat and the inner wall of the firing pin seat sleeve. The pressure relief gap is set on both sides of the firing pin seat body to improve its pressure relief effect.

[0035] Pressure relief structure embodiment 2:

[0036] The pressure relief structure is a groove structure 7 arranged at intervals at the end of the firing pin seat body.

[0037] The pressure relief structure may adopt a groove structure in addition to a cut surface structure.

[0038] Specifically, the firing pin has a connecting section 8 connected to the connecting hole, the connecting section 8 is provided with a through hole 9, the inner wall of the connecting hole is provided with a threaded hole 10, and the connecting section is extended into the connecting hole and connected through a connecting bolt 11; the threaded hole includes an internal threaded hole 12 extending into the connecting hole and a non-through hole 13 below the internal threaded hole; the connecting bolt includes a threaded section 14 threadedly matched with the internal threaded hole and a light column section 15 extending into the non-through hole and the through hole, and the top of the threaded section is provided with a hexagonal groove 17.
