Abstract

A stapler includes a main body, a magazine, a striker, and a driving portion. The main body encloses a receiving room and has an opening at a bottom of the front portion thereof. The front end and the rear end of the main body define a longitudinal direction. The opening communicates with the receiving room. The magazine is arranged in the main body for nails to be received in. The striker is arranged at the front portion of the main body and is linearly slidable above the opening vertically. The driving portion is disposed on the main body and is connected with the striker to drive the striker to move downward to strike the nail out. The striker has a terminal surface at the bottom end thereof. The terminal surface is recessed and has two opposite ends which are protruded.

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 accommodating space and has an opening below the front end thereof, the accommodating space is in communication with the opening, and the front end and the rear end of the body define a length direction; the nail shank is disposed in the body and is provided a plurality of staples are disposed; the striker is disposed at a front end of the body and can slide vertically linearly above the opening; the driving portion is disposed on the body and coupled with the collision plate to drive the collision plate to move downward to fire the staple Wherein, the bottom end of the striker is concave and has relatively convex opposite ends and a relatively concave intermediate portion.

Thereby, the nail gun provided by the invention can ensure that the nail needle is upright and not skewed, and provides a uniform pushing force to the nail needle, thereby avoiding the situation of the nail, and further ensuring that the nail needle and the next nail needle are surely separated, so as to avoid Pushing multiple staples or excess staples creates staples.

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, the present invention provides a nail gun comprising a body 10, a magazine 11, a striker 12, 12a, 12b and a driving portion.

The body 10 defines an accommodating space and has an opening under the front end thereof. The accommodating space is connected to the opening. The front end and the rear end of the body 10 define a length direction. The magazine 11 is disposed on the body. The plurality of staples 20 are accommodated in the 10; the striker 12, 12a, 12b is disposed at the front end of the body 10 and can slide vertically linearly above the opening; the driving portion is disposed on the body 10 and the collision plate 12, 12a, 12b are coupled to drive the striker 12, 12a, 12b to move downward to fire the staple 20. In this embodiment, the drive portion includes a pressure pin 13 located above the body 10; The bottom end 121 of the striker 12, 12a, 12b is concave and has relatively convex opposite ends and a relatively concave intermediate portion. The bottom ends 121 of the strikers 12, 12a, 12b are relatively convex. The end line is approximately parallel to the length direction.

Further, the bottom end 121 of the striker 12, 12a, 12b forms a recess 1211, 1211a, 1211b. In the main embodiment, the recess 1211 has a circular arc shape. However, in other implementations. In the example, the groove 1211a has a trapezoidal cross section, and the bottom surface of the groove 1211a has a width smaller than the opening width of the groove 1211a, as shown in FIG. 6; in another embodiment, the groove 1211b has a triangular cross section. The width of the groove 1211b is gradually expanded from the bottom of the groove 1211b toward the opening of the groove 1211b, as shown in FIG. The maximum depth of the grooves 1211, 1211a, and 1211b at the bottom end of the striker 12, 12a, 12b is 0.1 to 1 times the thickness of the striker 12, 12a, 12b along the length direction. Preferably, the The maximum depth of the grooves 1211, 1211a, 1211b of the bottom end 121 of the striker 12, 12a, 12b is approximately 0.25 to 0.5 times the thickness of the striker 12, 12a, 12b along the length direction.

Preferably, the two ends of the recesses 1211, 1211a, and 1211b of the bottom end 121 of the striker 12, 12a, 12b are inclined away from the recesses 1211, 1211a, and 1211b to form an oblique guide surface 1212, which is helpful. Separate the staples to avoid pinning.

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 side walls on both sides of the recesses 1211, 1211a, 1211b of the striker 12, 12a, 12b can contact the opposite side corners of the staple 20, and smoothly push the staple 20 downward, thereby ensuring the staple 20 moving direction is correct without skewing, even if the thickness of the staple 20 is reduced, the grooves 1211, 1211a, 1211b of the striker 12, 12a, 12b can surely contact the staple 20 in a two-point support manner to push the staple 20 out. The oblique guide surface 1212, in turn, helps to separate the adjacent staples 20, preventing the plurality of staples 20 from being pushed out to cause staples, and in addition, even the thicker staples 20 cannot be accommodated in the strikers 12, 12a, 12b. In the grooves 1211, 1211a, and 1211b, the protrusion between the grooves 1211, 1211a, and 1211b and the inclined guide surface 1212 can also be used for the two-point support, and the effect of stably pushing the nail 20 can be achieved. The bumper of the invention has the advantages of easy processing, low cost, no weight increase and great progress.
