Stapler

Abstract

A stapler stabilizing the stapling with less manufacturing procedure is provided. The front portion of the stapler (1) has a handle portion (6) of a press knife (1); the corresponding substrate portion (2) can be rotated in oriental way by a main shaft (20); the inner side of the handle portion (6) can be rotated in oriental way by a staple pin box portion (4) of the main shaft (20); the substrate portion (2) is provided with a machine station (23) leaning upwards; and the substrate portion (2) is provided with a concave station (22) at the same time of having a sliding plate (24) of a sliding supporting claw (52) allowing the machine station (23) sliding backwards in the descending direction; the handle portion (6) is provided with a plate spring (8); the lateral portion of the plate spring (8) can be provided in the form of downward protruding way; so that the sliding plate pushing and pressing portion (67) of the sliding supporting claw (52) and the plate spring (8) are formed integrally.

Description

technical field [0001] The present invention relates to a flatbed stapler in which the front end of a staple is flattened. Background technique [0002] As a stationery for binding paper, there is a stapler, and the stapler is an indispensable stationery for office supplies. Such a stapler includes a type in which the front end of the staple is bent after the sheets are bound, and a flat type in which the front end of the staple is flattened. In recent years, flat-bed staplers have become mainstream continuously, and there have been many proposals for such flat-bed staplers. [0003] For example, the stapler recorded in (Japanese Patent) Publication No. 6-44605 has the following components: an abutment with a concave platform; a staple box for accommodating staples; The handle member of the shaft; the pressing knife that is arranged at the front end of the handle member and pushes the staples in the staple box toward the concave table with the rotation of the handle member...

AI Technical Summary

Problems solved by technology

[0010] Even the stapler described in this patent document 3 does not rely on the amount of tension and displacement of the leaf spring to slide the slider pressing member, but only the amount of downward movement of the two wall portions of the slider pressing member. Sliding the slide plate toward the rear, like the staplers introduced in Patent Document 1 and Patent Document 2, the problem that the displacement amount is small when the front end of the pressing member moves backward is not solved.
