STAPLER

Abstract

A stapler includes a main body, a magazine, a striker, and a driving portion. The main body encloses a receiving space and has an opening at the bottom of the front end thereof. The opening communicates with the receiving space. The magazine is arranged in the main body for receiving staples. The striker is arranged at the front end of the main body and is linearly slidable above the opening vertically. The driving portion is disposed on the main body and is connected to the striker to drive it to move downward to strike the staple out. The striker has a bottom face oriented frontward and downward so that an angle ranged from 3-15 degrees is defined between the bottom face and the horizontal plane.

Claims

1. A stapler, including: a main body, enclosing a receiving space, having an opening at a lower part of a front end thereof, the receiving space communicating with the opening; a magazine, arranged in the receiving space of the main body, adapted for receiving a plurality of staples, the magazine extending along a horizontal direction to push the staples out horizontally; a striker, disposed on the front end of the main body, being linearly slidable above the opening along a vertical direction; an driving portion, disposed in the main body and connected to the striker, adapted for driving the striker to move downward to strike the staples out; wherein the striker has a bottom face at a bottom end thereof, the bottom face is a lowest face of the striker, when observing from a lateral side of the main body, the bottom face is oriented toward the front end of the main body and downward so that an angle is defined between the bottom face and a horizontal plane, the angle is ranged from 3 degrees to 15 degrees.

2. The stapler of claim 1, wherein the driving portion includes a pressing arm located above the main body.

3. The stapler of claim 1, further including a blocking structure, the blocking structure including an elastic element and a blocking element, the blocking element being disposed in front of the magazine and the striker, the elastic element being biased between the blocking element and the front end of main body so that the blocking element tends to move toward the magazine, the blocking structure being adapted for corresponding to staples in different sizes and shapes.

4. The stapler of claim 1, wherein a lowest portion of the bottom face of the striker corresponds to a rear portion of a staple to be stroke out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Please refer to FIGS. 1 to 5, 3A, and 4A, the stapler of the present invention includes a main body 10, a magazine 11, a striker 12, and a driving portion 13.

[0017] The main body 10 encloses a receiving space and has an opening at a lower part of a front end thereof. The receiving space communicates with the opening. The magazine 11 is received in the main body 10 for receiving staples 20. The magazine 11 extends horizontally to push the staples 20 out horizontally. The striker 12 is arranged at the front end of the main body 10 and is linearly slidable above the opening along a vertical direction. That is, the direction that the striker 12 slides along is perpendicular to the direction that the staples 20 are pushed out along. The driving portion 13 is disposed on the main body 10 and is connected to the striker 12 to drive the striker 12 to move downward to strike the staples out. In the present embodiment, the driving portion 13 includes a pressing arm above the main body 10. Specifically, the striker 12 has a bottom face at a bottom end thereof. When observing from a lateral side of the main body 10, the bottom face is oriented toward the front end of the main body 10 and downward so that an angle is defined between the bottom face and a horizontal plane. The angle is ranged from 3 degrees to 15 degrees. In addition, the lower portion of the bottom face of the striker 12 corresponds to a rear portion of the staple 20 to be struck out.

[0018] In the present embodiment, a blocking structure 14 is also included. The blocking structure 14 includes an elastic element 142 and a blocking element 141. The blocking element 141 is located in front of the magazine 11 and the striker 12. The elastic element 142 is biased between the blocking element 141 and the front end of the main body 10 so that the blocking element 141 tends to move toward the magazine 11 to correspond to staples in different sizes and shapes.

[0019] In conclusion, the striker 12 of the present invention has an inclined bottom face, so only the lower end of the striker 12 touches the rear portion of the staple 20 at the beginning so that the staple 20 receives a force clockwise (in FIGS. 4 and 4A). When the bottom face of the striker 12 further contacts the staple 20, the striker 12 continuously provides the force clockwise to the staple 20 to make the staple 20 move along the blocking element 141. Thus, the staple 20 can be stroke out along the blocking element 141 to prevent from failure of striking.
