Description

Nail gun

The invention relates to a nail gun.

The conventional nail gun has a body, a nail, a striker and a driving portion (usually a pressing handle, a trigger, etc.), the nail is located in the body for accommodating the nail, and the impact plate is disposed at the front end of the body. The longitudinal direction can be linearly slid, and the driving portion is coupled with the collision plate to drive it to move downward to fire the nail.

However, although the general nails have elastic members and the like, which tends to move the nails forward, the elastic force should not be too large to avoid the needles being bad when the nails are fired. However, this also causes the nails at the front end. There is not enough pushing force. When the striker touches the nail down, the lower end of the nail has a tendency to move toward the rear end of the nail, causing the nail to be skewed. As long as the nail is slightly skewed, it may not be successfully fired to form a card. The state of the nail not only fails to accomplish the purpose of the work, but also the internal parts of the nail and the nail gun.

The main object of the present invention is to provide a nail gun which can effectively reduce the rate of the nail and ensure the smoothness of the nail.

To achieve the above object, the present invention provides a nail gun comprising a body, a magazine, a striker and a driving portion.

The body enclosure has an accommodation space and has an opening below the front end thereof, the accommodation space is in communication with the opening; the magazine is disposed in the body and is accommodated by a plurality of staple pins; the collision plate is disposed in front of the body And a driving portion is disposed on the main body and coupled to the collision plate to drive the collision plate to move downward to fire the nail; wherein the bottom end of the collision plate has a bottom The end surface, the bottom end surface slightly faces the front end of the body and is at an angle to the horizontal plane, the angle being 3 degrees to 15 degrees.

Thereby, the nail gun provided by the invention can be used as a compensation means for the tendency of the nail to be skewed, ensuring that the nail is pushed out vertically, and the situation of the staple can be avoided.

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 FIG. 1 to FIG. 5 and FIG. 3A and FIG. 4A, the present invention provides a nail gun comprising a body 10, a magazine 11, a striker 12 and a driving portion.

The body 10 defines an accommodating space 101 and has an opening 102 below the front end thereof. The accommodating space 101 is connected to the opening 102. The magazine 11 is disposed in the body 10 and is accommodated by the plurality of pins 20; The striker 12 is disposed at the front end of the body 10 and can slide straight and straight above the opening 102 The driving portion is disposed on the body 10 and coupled to the collision plate 12 to drive the collision plate 12 to move downward to fire the nail pin 20. In the embodiment, the driving portion includes a pressure pin 13, which is pressed. The bottom end of the striker 12 has a bottom end surface 121, and the bottom end surface 121 slightly faces the front end of the body 10 and forms an angle θ with the horizontal plane. The angle θ is 3 degrees. To 15 degrees, more specifically, the bottom end surface 121 of the striker 12 has the lowest portion corresponding to the staple 20 near the rear end.

In this embodiment, a blocking structure 14 is further included. The blocking structure 14 includes an elastic member 142 and a stopping member 141. The blocking member 141 is located in front of the magazine 11 and the collision plate 12. The elastic member 142 is biased between the stopper 141 and the front end of the body 10 to move the stopper 141 toward the magazine 11 by the stopper structure 14 to correspond to different sizes and types of staples. .

With the above structure, the striker 12 of the nail gun provided by the present invention has a slanted bottom end surface 121, and only the lowest end touches the back end portion of the nail 20 at the beginning, and the nail pin 20 can be provided to approximate The force in the hour hand direction (in the direction of FIG. 4 and FIG. 4A), and then the bottom end surface of the striker 12 is further attached to the top surface of the staple pin 20, and the force of providing the needle pin 20 in a clockwise direction is continued. The stopper 141 at the lower end of the lower end of the 20 is moved downward to ensure that the nail 20 as a whole is closely pressed against the stopper 141, thereby preventing the nail 20 from being in close contact with the stopper 141 but moving downward. In the case of a staple, in addition, the anti-stapling measure of the present invention does not cause an additional cost increase at all, but can have a significantly improved nailing effect and is highly progressive.
