Labor-saving stapler

Abstract

The invention provides a labor-saving stapler, which belongs to the technical field of office appliances, and solves the problem that the operation of the existing stapler is laboursome. The stapler comprises a base, a pressing cover and a staple box, wherein the pressing cover can be pressed downwards under a pressure, and the staple box is arranged between the base and the pressing cover and used for placing staples; the tail ends of the pressing cover and the staple box are respectively hinged with the tail end of the base; in addition, the stapler also comprises an auxiliary upper cover, one end of the auxiliary upper cover is hinged with the middle part of the base, the other end of the auxiliary upper cover is a stressed end and arranged above the pressing cover, and a part above the pressing cover, of the auxiliary upper cover is provided with a force application bar; and when a downward applied force is exerted on the stressed end of the auxiliary upper cover, the force application bar can exert a downward applied force on the upper surface of the pressing cover, and in the process of pressing the auxiliary upper cover downwards, the force application bar can move forwardsalong the pressing cover. Through setting the auxiliary upper cover, the labor-saving stapler can achieve the effect of labor saving by using the lever principle, and the further downwards the auxiliary upper cover is pressed, the more labor force is saved; and meanwhile, the labor-saving stapler is simple in structure and low in cost, and can achieve a significant labor-saving effect.

Description

technical field [0001] The invention belongs to the technical field of office appliances, and relates to a stapler, in particular to a labor-saving stapler. Background technique [0002] The stapler is a commonly used office product. The common stapler structure includes a base, a staple box hinged on the base, and a cover. , after the staples in the staple box are pressed down and penetrate the paper through the staple pressing sheet on the cover, the staples are folded inward or outward through the folding foot plate. [0003] For the convenience of portability and use, the length of the general stapler is not large, so it needs to apply a lot of pressure when using it, especially when binding a lot of paper, it takes a lot of force to complete, and sometimes it is even impossible to complete the binding. For the elderly, children or women with less strength, it will inevitably bring great inconvenience. Especially for the staff who need to use the stapler for a long tim...
