Labor-saving stapler

Abstract

The invention relates to a labor-saving stapler, which comprises a base, a staple box, two connecting rods, a pressing rod and an outer cover. The labor-saving stapler utilizes the special length of the arm of force to save 60 percent of force application, wherein the components of the stapler are combined by pivot joint in a single fulcrum, so that the labor-saving stapler has the advantages of easy processing and no need of considering the precision of a hole site. In addition, pressing force is transmitted in the way of surface contact when both ends of the outer cover are pushed against the pressing rod, and as a result, the pressing rod has better structural strength and the effect that the outer cover indeed drives the pressing rod. Actually, the invention provides a stapler simultaneously having the advantages of excellent structural strength, easy processing and better labor-saving effect.

Description

technical field [0001] The invention relates to a stapler. Background technique [0002] Staplers have become an indispensable stationery in the industrial and commercial society. Staplers must be used for binding documents and organizing materials. 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 the People's Republic of China Patent Publication No. CN2902712 "Labor-saving stapler", it is a stapler that includes a labor-saving rod assembly. The labor-saving rod assembly includes a labor-saving rod and a coupling rod. , and located above the rear end of the staple case, the rear end of the pressing rod and the rear end of the box cover, the front end of the connecting rod is pivotally arranged on the pressing rod, and the rear end is pivotally arranged on the labor-saving rod. Using the combination of labor-saving rods, connecting parts and fixing frames at specific positions ...

AI Technical Summary

Problems solved by technology

[0005] However, although such a labor-saving stapler meets the user's labor-saving requirements, it still has some deficiencies and needs to be improved urgently.

The seat pivot frame of this stapler is fixed on the base in an inseparable manner. When the bracket is fixed on the seat pivot frame, it is restricted by the buckle body and the pressing arm at the same time, and it is impossible to connect the pressing arm and the pressing arm like an ordinary stapler. The button body is pivoted upwards to install the staples. The needle magazine must be pulled out from the rear of the stapler before the staples can be loaded. Although the purpose of staples has been completed, users need to change their operating habits because they are different from traditional staples. , there is indeed an inconvenience

[0006] In addition, one end of the flange of the button body is extended to form two single sheets. It is worth noting that the button body is a stressed part, and the single sheet body is easy to deform when it is stressed. When the button body is deformed, the stapler is almost lost. effect

[0007] In addition, the button body and the pressing arm use the flange to cooperate with the joint groove. When there is a processing error in the position of the joint groove, the two cannot cooperate smoothly, or, although the two can barely cooperate, they are prone to dead spots. Causes the stapler to not operate smoothly

[0008] Although the aforementioned two kinds of staplers are known for their labor-saving effect, they still have insurmountable deficiencies, and there is a need for improvement.
