Problems solved by technology

[0004] However, the pivot joint between the middle member and the upper cover in the U.S. patent is limited by the stroke of pressing down the upper cover and cannot move to the pivot joint between the upper cover and the base, so the labor-saving effect provided by it is limited.
[0005] In view of the fact that the labor-saving effect of the US patent cannot fully meet the needs of users, there is still a need for improvement for users who need to use a stapler to bind documents for a long time

Abstract

The invention discloses a labor-saving stapler, which comprises a base, a needle box, a pressure lever, an outer cover and a plurality of connecting rods. Two ends of the connecting rods are provided with a first hole and a second hole respectively; by means of a pressing part for pressing the outer cover, the plurality of connecting rods are linked with the pressure lever, and a staple driving sheet combined on the pressure lever further produces a binding effect; and the distance between a pivoted part of the outer cover and the base and a pivoted part of the outer cover and one of the connecting rods is shorter than the distance between the pivoted part of the outer cover and the base and the pressing end. The force is transferred to the pressure lever by using the lever principle of the connecting rods, and the force arm of the outer cover has great labor-saving effect, so the staple driving can achieve the labor-saving effect.

Description

technical field [0001] The invention relates to a stapler, in particular to a stapler capable of achieving a better labor-saving effect. Background technique [0002] Staplers have become an indispensable stationery in the industrial and commercial society. Staplers must be used for binding documents and organizing data. In view of the wide frequency of use of staplers, a stapler with labor-saving function has become the first choice of users. [0003] Referring to U.S. Patent No. 7140526 "STAPLER", its base is provided with two pivot points, the first pivot point pivotally connects the needle box and the nailing assembly, the second pivot point pivotally connects the intermediate member and the upper cover, the role of the nailing assembly The force is equal to the reaction force of the needle box, and the upper cover relies on the design of the intermediate member, so that the length of the upper cover is much greater than the distance between the pivot point of the upper...
