The applicant first explains here that in the embodiments and drawings to be described below, the same reference numerals denote the same or similar components or structural features.

As shown in Figures 1 to 3, the nail gun 10 that is automatically applicable to a variety of nails provided by the first preferred embodiment of the present invention includes a housing 20 and a pressure rod extending from the inside of the housing 20 to the outside 30, and a nail box 40, a nailing member 50, a guide 60, a baffle 70, and an elastic member 80 arranged in sequence inside the housing 20.

The shell 20 is composed of a left shell 22 and a right shell 24, and the shell 20 has a closed front end 26, as shown in FIG.

The pressing bar 30, the nail box 40, the nailing part 50 and the guide part 60 are no different from the conventional nail guns. Wherein, the nail box 40 includes a base body 41, a spring 42 arranged in the base body 41, and a nail pusher 44 straddling the base body 41 and pushed against by the spring 42, as shown in Fig. 5 and Fig. 6 As shown, the nail box 40 is used to set a plurality of nails 90 connected in a row at the front end of the nail pushing member 44. The present embodiment takes the ㄇ-shaped nails as an example, but it is not limited thereto.

The guide member 60 is embedded in the shell 20, and abuts against the front end 412 of the seat body 41 of the nail box 40 with a rear surface 62 thereof. The guide member 60 has a guide groove 64 recessed from the rear surface 62, and the guide groove 64 has a penetrating portion 642 penetrating through the rear surface 62 and the front surface 66 (as shown in FIG. 3 ). The nail driver 50 can be driven by the compression rod 30 to move up and down along the guide groove 64 .

As shown in Figure 3, the baffle plate 70 includes a main body 72, and two wings 74 integrally connected to the two sides of the main body 72 respectively. The main body 72 has a front abutment surface 722, a rear abutment surface 724, and a The three guide grooves 726 of the abutting surface 724 .

As shown in Figure 3 and Figure 7, the elastic member 80 is generally an inverted L-shaped plate body, has a horizontal fixing portion 82, and a vertically extending downward from the fixing portion 82 substantially perpendicular to the fixing portion 82. The engaging portion 84 , and a moving portion 86 extends longitudinally downward from the engaging portion 84 and bends slightly in a direction opposite to the fixed portion 82 . The above-mentioned shapes of the fixing portion 82, the connecting portion 84, and the moving portion 86 are examples, and no matter what the shape is, as long as the elastic member can generate elastic force, it belongs to the technical characteristics of the present invention.

As shown in FIGS. 2 and 4 , the fixed portion 82 of the elastic member 80 is embedded in the slot 262 of the housing 20 , and the moving portion 86 of the elastic member 80 abuts against the baffle plate 70 in a relatively flat shape due to slight elastic deformation. The front abutment surface 722 of the front abutment surface 722, thus, the elastic member 80 provides the elastic force that pushes the baffle plate 70 toward the direction of the nail box 40, and then makes the baffle plate 70 abut against the front surface 66 of the guide member 60 with its wings 74 And be clamped between the elastic member 80 and the guide member 60 . In this way, the rear abutting surface 724 of the baffle 70 is opposite to the nail box 40 through the through portion 642 of the guide 60 , and there is a gap 12 between the baffle 70 and the nail box 40 (as shown in FIG. 5 ).

When the nail box 40 is equipped with a nail 90, the gap 12 can accommodate a nail 90 to be fired, and at this moment, the nail 90 to be fired is to lean against the rear abutment surface 724 of the baffle plate 70 (nails of other shapes may located in the guide groove 726 of the baffle 70, such as a T-shaped nail or a straight nail), and the baffle 70 will be displaced toward the front end 26 of the housing 20 due to the thrust of the nail 90 and the nail pushing member 44, and at the same time the elastic member The moving portion 86 of the housing 80 is then slightly elastically deformed and displaced toward the front end portion 26 of the housing 20 . The nail 90 to be fired will be hit downward by the nail driving part 50 when the user depresses the depression bar 30, and moves downward along the guide groove 64 of the guide part 60 (the nails of other shapes may move along the baffle plate). 70 guide groove 726 to move down, such as T-shaped nails or flat nails).

The size of the aforementioned gap 12 can be designed in conjunction with the elastic force of the spring 42 of the nail magazine 40 and the elastic member 80, so that when the nail magazine 40 is equipped with a nail 90 with a smaller thickness, the nail 90 to be fired will just be completely located in the gap 12. When the nail box 40 is equipped with a thicker nail, the nail can push the moving part 86 of the baffle plate 70 and the elastic member 80 toward the front end 26 of the housing 20 when the nail is hit by the nail driving part 50, and the moving part 86 will push the baffle plate 70 toward the direction of the nail box 40 by elastic force after the nail is driven out, so that the distance between the baffle plate 70 and the front end 412 of the nail box automatically follows the nail during the short period of hitting the nail. The thickness of the nail is adjusted to allow the nail to pass through. In this way, the nail gun 10 can be applied to nails of various thicknesses without being switched by the user, and as long as the thickness of the nails is within the range of automatic elastic adjustment of the distance between the baffle plate 70 and the nail box 40 Applicable, so the applicability of the nail gun 10 is better and the operation is convenient.

As shown in FIG. 8 , the difference between the nail gun 10 ′ provided by the second preferred embodiment of the present invention and the aforementioned nail gun 10 is that the elastic member 80 ′ of the nail gun 10 ′ is integrally extended from the inside of the left housing 22 That is to say, the fixing part 82' of the elastic member 80' is integrally formed and connected with the housing 20, so that the effect as described in the foregoing embodiments can also be achieved.

Alternatively, the elastic part of the nail gun provided by the present invention may not be in the form of a plate as provided in the foregoing embodiments, but may be other types of elastic parts, as long as the elastic part can move the baffle plate 70 toward the nail box 40 It only needs to push against the direction of the baffle plate 70 and allow the baffle plate 70 to be displaced toward the front end portion 26 of the housing 20 under force.

Finally, it must be stated again that the constituent components disclosed in the foregoing embodiments of the present invention are only illustrative examples and specific embodiments enumerated for implementing the present invention, and are not intended to limit the scope of the present case.
