Description

Stapler with flat stitch

technical field

The present invention relates to a stapler related to office supplies, in particular to a stapler equipped with a flat needle means capable of bending the stitches of a staple evenly.

Background technique

Generally, after the traditional stapler bends the pins of the staples, the thickness of the staples will increase due to the bent part of the pins, and it will easily cause the staples to slip off, and the tip of the pins is easy to deform and protrude and stab the user. Therefore, in recent years, related companies have successively developed and designed staplers that can bend and flatten the pins of staples. The specific structural form of existing staplers with flat stitching functions is generally such as the certificate number of Taiwan, China. Invention patent No. I229026 "stapler" and China Taiwan certificate No. I274637 "stapler" patent and other patent cases.

In the patent No. I229026, it is disclosed that the pressure handle is connected with the flat needle assembly through a ㄑ-shaped transmission part. The bent part of the middle section of the ㄑ-shaped transmission part is hooked to the needle case assembly, so that the pressure handle is pressed down. The flat needle assembly can be pushed through the ㄑ-shaped transmission part. In the design of the transmission means disclosed in the I229026 patent, since the force application point of the ㄑ-shaped transmission part is located at the front end of the pressure handle, the operation is relatively laborious and easily affects the comfort of the operation. At the same time, after actual operation and use, it is believed that this patent still has many components, and is not easy to manufacture and assemble. In addition, when it is desired to load staples, it is necessary to open the components at a relatively large opening angle. Not only the required operating space is relatively large, but also the problem that it is difficult to place the stapler on a flat surface to fill the staples will occur, which will affect the convenience of the stapler's operation and use.

In the patent No. I274637, it is disclosed that a pressing handle is connected with a flat needle assembly through a sliding part that is slidably combined with the needle box. When the pressing handle moves downward, the sliding part can be driven by the pushed part of the sliding part. The sliding part slides backward, so that the toggle arm of the sliding part can push the flat needle assembly, and the needle groove part used for bending the stitches is arranged under the needle groove hole of the flat needle assembly. The design of the transmission means disclosed in the I274637 patent is not conducive to industrial implementation and utilization due to the complex assembly form and linkage means of the slider, and the design of the slider slidingly assembled on the needle box, the pressure handle is downward. The force cannot be effectively converted into an active force driving the sliding member to slide backward, which greatly limits the operating ability and comfort of the stapler.

Furthermore, based on the consideration of the force-applying ability and the comfortable feeling of the hands generated by the operation of the stapler, the applicant previously filed a patent application for a "labor-saving stapler" and obtained the Taiwan Patent No. M299629. This patent uses the form of leverage principle to design the driving method of the pressure handle to achieve the effect of labor-saving operation. However, after the applicant's actual operation and use, he thinks that this patent still has many components, and is not easy to manufacture and assemble, and it needs to be opened at a relatively large opening angle when it is desired to load staples. The pressure handle assembly not only requires a large operating space, but also has the problem of being difficult to place on a flat surface to fill the staples, which affects the convenience of the stapler.
