Description

Automatic nail gun for a variety of nails

The present invention relates to nail guns, and more particularly to a nail gun that is automatically adaptable to a variety of nails.

There are many nail guns on the market that can be used for nails of various shapes. The nails can accommodate T-shaped nails, in-line nails, staples, dowels, etc., and can be used to position the nails with a pusher. The position to be fired under the nailing member is pushed forward, so that the user can drive the nailing member to hit the nail located at the position to be fired downward by a pressing rod.

For nails with different thicknesses, the user must switch one of the control elements of the nail gun so that the position to be fired just accommodates one nail, thereby avoiding the situation where two nails are simultaneously hit, or the nail hitting only The first half of a nail can not be successfully hit by the nail.

However, after the user installs the nail, the user often forgets to switch the control member, resulting in the above two kinds of mistakes. In addition, the control member can usually only switch between two-stage or three-stage, that is, the aforementioned nail gun generally only applies two or three nails of a specific thickness, so the applicability is slightly insufficient.

In view of the above-mentioned deficiencies, the main object of the present invention is to provide a nail gun that can automatically apply nails of various specifications and thickness without switching by a user, thereby increasing the convenience of operation.

Another object of the present invention is to provide a nail gun which can be applied to a variety of specifications and has a thickness that does not require a specific size of the nail, so that the applicability is preferred.

In order to achieve the above object, the nail gun of the present invention which is automatically applicable to a plurality of nails comprises a casing, a magazine, a baffle and an elastic member. The outer casing has a front end portion. The magazine is disposed in the housing for setting a plurality of nails. The baffle is disposed between the front end of the outer casing and the magazine with a gap therebetween, and the baffle has a front abutting surface facing the front end of the outer casing, and faces the nail and the same A rear abutment surface for the nail to abut, and a guide groove provided on the rear abutment surface for guiding the nail. The elastic member is disposed between the front end portion of the outer casing and the front abutting surface of the baffle to provide an elastic force for pushing the baffle toward the nail, and the baffle can be pushed by the nail It is displaced toward the front end of the outer casing.

Thereby, the gap between the baffle and the nail can accommodate a nail to be fired, and the nail can push the baffle toward the front end of the outer casing when struck, so that the baffle and the nail are pressed The distance between the nails is automatically adjusted to the thickness of the nail and is just passed by a nail. Therefore, the nail gun can be applied to nails of various thicknesses without the user switching, and as long as the thickness of the nail is attached to the baffle. The distance from the nail can be applied within the range of automatic elastic adjustment, so the applicability of the nail gun is better.
