Flat needle stapler with needle groove sheet track structure

Abstract

The invention provides a flat needle stapler with a needle groove sheet track structure, which is characterized in that a base is provided with a track structure; the track structure is fixedly arranged on the bottom surface of the base and comprises at least one track frame which is convexly arranged on the bottom surface of the base; the track frame and the two side walls of the base can be spaced with each other, and a track is arranged on the track frame so that a needle groove sheet can be glidingly accommodated in the track of the track frame, thereby, the invention provides the stapler which can make the needle groove sheet stably move and improves the quality of a flat needle.

Description

technical field [0001] The invention relates to a stapler, in particular to a flat needle stapler with a needle groove track structure. Background technique [0002] In order to improve the quality of binding, most of the existing staplers are equipped with a flat needle device, which makes the stitches of the staples flush with a needle groove, so as to avoid the curved stitches from piercing the document or stabbing the user. , and some of the needle groove sheets of the flat needle device of the existing stapler are in a fixed form, but the existing fixed needle groove sheet is fixed on the base of the stapler. There is a break distance between the pin grooves, and there may be doubts about poor quality when the staples and the pin grooves collide quickly. [0003] In addition, there is a slidable needle groove sheet, but the existing slidable needle groove sheet tends to be inclined when moving, which cannot provide a good flat stitch effect, and needs further improveme...

AI Technical Summary

Problems solved by technology

[0006] 1. The non-functional area 922 of the needle groove sheet 92, that is, the parts on both sides that are not used for flat stitches, is exposed outside the guide groove 902, so it is easy to affect the action of the needle groove sheet 92 due to external factors. For example, if When there is a foreign matter between the non-functional area 922 and the inner wall of the base 90, the pin groove plate 92 is easy to get stuck with the foreign matter, which affects the smoothness of the needle groove plate 92 when moving

[0007] 2. The width of the needle groove sheet 92 must be large enough to allow both sides to extend into the guide groove 902, or the width of the stapler base 90 needs to match the width of the needle groove sheet 92, which will be limited by the size of the two. , and relatively restrict the size and design space of other components
