Please refer to FIG. 3 again, the moving part 60 is a bolt body, which passes through the through hole 322 of the first side wall 32, the first guide hole 422 of the third side wall 42, the trigger according to a threading direction. The pivot hole 54 of the inner panel 50 , the second guide hole 442 of the fourth side wall 44 and the through hole 342 of the second side wall 34 . The moving member 60 has a top 62 , a rod 64 extending outward from the top 62 , and an end 66 extending outward from the rod 64 , wherein the end 66 has a limiting block. 662 and a moving block 664, wherein the cross-sectional diameters of the rod portion 64 and the limiting block 662 are approximately equal to the diameters of the two through holes 322, 342, therefore, when the rod portion 64 and the limiting block 662 respectively pass through When it is in the two through holes 322, 342, it can only rotate in the respective through holes 322, 342, and cannot move perpendicularly to the piercing direction. The cross-sectional dimension of the limiting block 662 is substantially consistent with the opening dimension of each of the first limiting hole 446 and the second limiting hole 448, so that the first limiting hole 446 or the second limiting hole can be engaged. 448, the length of the limiting block 662 is greater than the total thickness of the second side wall 34 and the fourth side wall 44, and the part protruding from the second side wall 34 is provided with an annular groove 666 surrounding it for A stopper 68 is embedded therein, and the stopper 68 will be blocked around the through hole 342 of the second sidewall 34 and cannot pass through the through hole 342 , so as to prevent the limiting block 662 from breaking away from the through hole 342 . The moving block 664 is located between the rod portion 64 and the limiting block 662, and is arranged and adjacent to the limiting block 662 along the length direction of the moving member 60, and its length is greater than the thickness of the fourth side wall 44 , its cross-sectional diameter is smaller than that of the limiting block 662, and can pass through the space between the two protrusions 444, so it can slide in the first limiting hole 446 and the second limiting hole 448, The moving part 60 is caused to slide in the first guide hole 422 and the second guide hole 442 perpendicular to the threading direction or the length direction of the moving part 60 , thereby driving the trigger inner piece 50 to move.

In this embodiment, the elastic member 70 is a spring, sleeved on the rod portion 64 of the moving member 60 , and located between the first side wall 32 of the outer trigger 30 and the top 62 of the moving member 60 . When the top 62 of the moving piece 60 is pressed, and the moving piece 60 is pushed along the threading direction or the length direction of the moving piece, the elastic piece 70 is compressed to generate a restoring force, and at the same time, the moving block 664 moves into the first The second guide hole 442 of the four side walls 44, the limiting block 662 moves out of the second guiding hole 442 of the fourth side wall 44, because the moving block 664 can slide between the first limiting hole 446 and the second guiding hole 442. In the two limiting holes 448, therefore, the user can slide the moving part 60 at this time, causing the trigger inner sheet 50 to move to the single-shot or continuous firing state; after the adjustment is completed, the user only needs to release the trigger. The top 62 of the moving part 60 , the elastic force of the elastic part 70 will immediately reset the stopper 662 and engage with the first stopper hole 446 or the second stopper hole 448 to fix the fired state.

Through the above structure, when the nail gun 10 is in the single firing mode, the moving part 60 is located in the second limiting hole 448, as shown in FIG. Push the trigger inner piece 50 first, and then the user presses the outer trigger 30, so that the trigger inner piece 50 completely pushes the firing switch pin 124, so that the high-pressure air externally connected to the nailing gun 10 is introduced into the nailing gun 10 The main body 12 impacts the nail to complete the firing action; and after the user presses the outer trigger 30, as shown in Figure 5, the trigger inner piece 50 is separated from the safety bar 122, so the user cannot continuously make the nailing Gun 10 shots. On the contrary, when the nail gun 10 is in the continuous firing mode, the moving part 60 is located in the first limiting groove 446, as shown in Fig. 6 and Fig. 7, in this case, the trigger inner piece 50 extends The length of the main body 12 of the nail gun 10 is longer than that in the single-fire mode, so after the user depresses the outer trigger 30, the trigger inner piece 50 will not disengage from the safety lever 122 to achieve the effect of continuous firing.

Through this, the firing state switching device 20 of the nail gun 10 provided by the utility model has a simple structure, and the user can easily switch between the single firing state and the continuous firing state with only two fingers of one hand, achieving convenient operation sexual purpose.

The above is only a detailed description and illustration of the preferred embodiments of the present utility model, and all embodiments that conform to the spirit of the patent scope of the utility model and its similar changes are included in the scope of the utility model, any Within the field of the utility model, those who are familiar with the art can easily conceive of changes or modifications that can be covered by the following patent scope of this case.
