Referring to FIG. 1 , a stapleless and non-fired structure of a nail gun disclosed in a first embodiment of the present invention is mounted on a nail holder 20 of a nail gun 10 and corresponds to a nail mounted on the nail gun 10 .匣30. The structure includes a stop 40 that is movable and a safety member 50. An upper cover 60 is mounted on one side of the nail holder 20 and covers the stopper 40 and the safety member 50.

Referring to FIG. 2, the nail holder 20 has a panel 22 and a bottom plate 24 attached to one side of the panel 22. The panel 22 is provided with a first through hole 26 . The bottom plate 24 is provided with a second through hole 28 having an inclined surface portion 281 at an end angular position. The surface 22 is combined with the bottom plate 24, and the second through hole 28 and the first through hole 26 are in a dislocated state. In this embodiment, the number of the first through holes 26 and the second through holes 28 is two.

The stop 40 is movably mounted to the ejection seat 20. The stopping member 40 has a first blocking portion 42 and a second blocking portion 44 connected to the first blocking portion 42. The first stop portion 42 and the second stop portion 44 of the stopper 40 are in a dislocated state. The stop member 40 further has a passage 34 formed at the junction of the first stop portion 42 and the second stop portion 44. The wall mask of the passage 34 has an inclined portion 36. The stopping member 40 is mounted on the ejection seat 20 such that the first blocking portion 42 is located in the first through hole 26 of the panel 22, and the second blocking portion 44 is located in the second through hole 28 of the bottom plate 24, And one end of the second blocking portion 44 corresponds to the inner space of the magazine 30.

The safety member 50 has a touch portion 52 and a linkage portion 54 connected to the touch portion 52. The safety member 50 is movably mounted on the nail holder 20, and the touch portion 52 is located on the panel 22 and Between the bottom plates 24. One end of the touch portion 52 is opposite to the stopper 40, and the other end can protrude from the nail holder 20. The securing member 50 is displaced such that the touch portion 52 moves toward or away from the stop member 40 with respect to one end of the stop member 40.

Referring to Figures 3 and 4, the magazine 30 houses at least one nail 32. In the present embodiment, the nail 32 can be a U-shaped row of nails, and the nail 32 can be biased by an appropriate thrust. The nail base 20 is displaced. When the stopper 40 is pushed by the nail 32, the stopper 40 will protrude outward (the direction is upward), so that the stopper 40 is formed in a first position. It should be noted that the passage 34 exposes the bottom plate 24 when the stop member 40 is in the first position.

Referring to FIG. 5, when the nail 32 is not in the nailed state, the stopper 40 is not pushed by the nail 32, so the stopper 40 falls to the magazine 30. Further, the stopper 40 is formed in a state of being in a second position. When the stop member 40 is in the second position, the bottom edge of the first stop portion 42 rests on the bottom plate 24 and the passage 34 is not exposed.

Referring to FIGS. 6 and 7 , in actual use, the stopper 40 is pushed against the nail 32 and formed in the first position, and the touch portion 52 of the safety member 50 protrudes from the nail holder 20 .

One end of the touch portion 52 is allowed to enter the passage 34 (as shown in FIG. 6), so that the nail gun 10 can be fired.

Referring to Figures 8 and 9, when there is no nail in the magazine 30, no appropriate urging force acts on the stopper 40. In other words, the stop member 40 is in the second position due to the fact that the stop member 40 is not pushed by the nail, and the first stop portion 42 of the stop member 40 faces the touch portion 52. One end is used to block the displacement of the safety member 50 (as shown in FIG. 9), so that the nail gun 10 is in a state in which no nails can be fired.

In addition, the wall surface of the passage 34 has the inclined portion 36. The end position of the second through hole 28 has the inclined surface portion 281. When the stopper 40 is located at the second position, the inclined portion 36 abuts the inclined portion. 281, this ensures that the channel 34 is not exposed.

Referring to FIG. 10, if the nail (U-shaped nail) 32 is installed in the wrong direction (up and down direction), the stopper 40 is displaced downward, thereby making the stopper The first blocking portion 42 of the 40 is opposite to the engaging portion 52 of the securing member 50. Thus, the securing member 50 is to be displaced, and one end of the engaging portion 52 is blocked by the first blocking portion 42, so that the nail is caused. The gun 10 is in a state in which it cannot be fired. It can be seen from the above that the structure disclosed by the present invention not only allows the nail gun 10 to achieve the purpose of no nails and non-fire, but also has the effect of preventing the user from installing the nail 32 in the wrong direction (the function of preventing the nail).

Referring to FIG. 11, the main structure of the second embodiment of the present invention is the same as that of the first embodiment. The difference is that the number of the first through hole 26, the second through hole 28 and the stop member 40 is As one, and in the present embodiment, the nail 32 used in the nail gun 10 may be a T-shaped nail. In this embodiment, the use of the stopper 40 and the safety member 50 is the same as that of the first embodiment, and details are not described herein.

According to the above description, the present invention can be matched with the first through hole 26 and the second through hole 28 of the nail holder 20 by the structure of the stopper 40, and the stopper 40 and the insurance. The corresponding form of the piece 50 can make the nail gun 10 achieve the purpose of achieving no nails and non-fire, thereby providing the effect of preventing the nail 32 from being installed in the wrong direction and being accidentally hit.
