Description

Nail gun

The invention relates to a nail gun.

The conventional nail gun includes a body and a magazine disposed at the bottom of the body. The nail is clamped inside the body by a fastening mechanism. The fastening mechanism can be released by operating a switch to exit the nail. Nailed. However, in the bottom nail gun, the pressing direction of the nail switch is opposite to the loading direction (bottom side upward). When the user wants to load the nail, the problem of the wrong nail position is often installed.

Therefore, it is necessary to provide a novel and progressive nail gun to solve the above problems.

The main object of the present invention is to provide a nail gun which can prevent the position of the nail from being wrong.

In order to achieve the above object, the present invention provides a nail gun, comprising: a nail gun body, comprising a bottom side, and a nail opening and a notch provided on the bottom side; and a nail cartridge removably received in the nail The nail gun body includes a nail rail portion for arranging the nail member and a card abutting portion located outside the nail rail portion; a latching mechanism is located on the bottom side, and includes a nail gun body disposed at the nail gun body a pressing handle, the pressing handle is provided with a resisting portion, the resisting portion is movable between a resisting position and a releasing position; wherein when the resisting portion is located in the resisting position, the resisting portion can be blocked from the card The nail cannot be withdrawn from the nail gun body; when the resisting portion is in the release position, the resisting portion is disengaged from the latching portion and the magazine can be withdrawn from the nail gun body.

The following is a description of the possible embodiments of the present invention, and is not intended to limit the scope of the invention as claimed.

Referring to FIGS. 1 through 5, there is shown a first preferred embodiment of the present invention. The nail gun 1 of the present invention includes a nail gun body 10, a magazine 20 and a catch mechanism 30.

The nail gun body 10 includes a bottom side 11 and a nail opening 12 and a notch 13 disposed on the bottom side 11; the magazine 20 is removably received in the nail gun body 10, and the magazine 20 includes a nail rail section 21 for arranging the nail member and a card abutting portion 22 located outside the nail rail segment 21; the latching mechanism 30 is located at the bottom side 11 and includes a nail gun body 10 disposed at the notch The pressing handle 31 of the 13 is provided with a resisting portion 311 movable between a resisting position and a releasing position; wherein the resisting portion 311 is located in the resisting position, the resisting portion The 311 is slidable to the yoke 20 and the yoke 20 cannot be detached from the lance body 10; when the resisting portion 311 is in the release position, the resisting portion 311 is disengaged from the yoke 22 and the yoke 20 can Exit the nail gun body 10. Thereby, the latching mechanism 30 is naturally operated by the bottom side 11 upwardly to withdraw the magazine 20, and the intuitive operation ensures that the nailing position is correct.

The pressing handle 31 is pivotally disposed on the nail gun body 10, and the locking portion 22 includes a slope 221 facing a pivot point 312 of the pressing handle 31. The resisting portion 311 extends toward the magazine 20 to stably resist Connected to the slope 221. However, the pressing handle can also be connected to the nail gun body in other manners; the engaging portion can also be an arc convex surface, a concave surface and the like. The pressing handle 31 is rotatable from the notch 13 toward the inside of the nail gun body 10. The pressing handle 31 includes a pressing portion 313 exposed to the notch 13 and a blocking arm 314 extending into the bottom side 11 . The pressing portion 313 and the blocking arm 314 extend from the pivoting point 312 of the pressing handle 31. The pressing portion 313 and the blocking arm 314 can be reversely oscillated on opposite sides of the pivoting point 312. Preferably, the blocking arm 314 is integrally formed with a protrusion 315. The protrusion 315 is provided with the resisting portion 311, and has good structural strength and can stably abut against the engaging portion 22. However, the bumps may also be non-integrally connected to the blocking arm. The pressing portion 313 and the blocking arm 314 are pivoted from the pivoting point 312 to the interior of the nail gun body 10, whereby the blocking arm 314 and the bottom side 11 have a pivotable space, and the pressing portion 313 It does not protrude from the gap 13 to avoid accidental touch during use.

The notch 13 is opened on the bottom side 11 in a direction away from the nail opening 12, and the pressing portion 313 can be reliably pressed without interference. Preferably, the bottom side 11 includes a lip 14 defining the notch 13. The pivot point 312 of the pressing handle 31 is located inside the lip 14. When the resisting portion 311 is in the resisting position, the pressing portion is pressed. The portion 313 abuts against the lip 14 outwardly, and the pressing handle 31 does not pivot excessively and the resisting portion 311 can accurately abut against the engaging portion 22 .

In the present embodiment, the magazine 20 is further provided with a spring arm 23 which is biased outwardly against the pressing handle 31 to maintain the resisting portion 311 in the blocking position. The elastic arm 23 is integrally extended by the magazine 20, and the structural strength is better. However, the elastic arm can also be additionally connected to the magazine. The pressing handle 31 further includes a retaining projection 316 protruding toward the interior of the nail gun body 10. When the resisting portion 311 is in the resisting position, the elastic arm 23 is engaged with the retaining projection 316 and is not easily slipped. The pressing handle 31 preferably further includes a slanting tail portion 317 extending obliquely outward from the blocking projection 316 to ensure that the pressing portion 313 can rotate toward the inside of the nail gun body 10. Preferably, the pressing handle 31 further includes a recess 318 adjacent to the retaining projection 316. The recess 318 is disposed on the oblique tail portion 317 and extends away from the resisting portion 311 when the pressing handle 31 faces the When the inner portion of the nail gun body 10 rotates, the elastic arm 23 disengages from the blocking protrusion 316 and slides along the groove 318, so that the magazine 20 can smoothly exit the nail gun body 10.

The nail gun 1 preferably further includes an elastic member 40 disposed between the nail gun body 10 and the magazine 20, and the elastic member 40 pushes the magazine 20 away from the nail opening 12. Thereby, when the resisting portion 311 is moved to the release position, the magazine 20 can be pushed out of the nail gun body 10 by the elastic member 40, as shown in FIGS. 4 and 5.

Please refer to FIG. 6 and FIG. 7 , which shows a second embodiment of the present invention, which is different from the foregoing embodiment in that the magazine 20a is not provided with the elastic arm, and the nail gun further includes a bottom side 11 . The elastic member 50 between the inner surface and the pressing handle 31 is such that the resisting portion 311 is normally located at the resisting position, and the same effect can be achieved. The elastic member 50 can be, for example, a spring or a spring piece or the like. However, the elastic member may also be disposed between the other position inside the nail gun body and the pressing handle.
