Stapler capable of punching

Abstract

The invention discloses a stapler capable of punching. A shaft hole plate is a long plate with a hole; a rotating shaft passes through the through hole of the shaft hole plate; two punching pins are connected with the rotating shaft; a brace rod is connected with two ends of the rotating shaft; a lower positioning piece is arranged on the side surface of a pin storage box; an upper positioning piece is fixedly arranged on the inner side of the top surface of a pressing handle; the upper plate of a base is provided with two parallel slots and is further provided with two pin penetrating holes; a spring box is arranged in the base and is contacted with the upper plate of the base; an adjusting nut is connected with the spring box; a spring is arranged in the spring box and is used for enabling the heads of a movable retaining fork to extend out of the slots of the base; a fixed retaining fork is arranged at the rear part of the spring box and is connected with the spring box through a connection plate; the distance between the movable retaining fork and a bending slot is equal to that between the fixed retaining fork and the pin penetrating holes; a support plate is arranged at the rear part of the fixed retaining fork; one end of the adjusting rod is provided with an adjusting knob, and the other end of the adjusting rod is provided with a ring-like clamping slot, wherein the ring-like clamping slot is matched with the through hole of the support plate; and a middle outer thread of the adjusting rod is matched with the adjusting nut. The stapler capable of punching is simple in structure, is reliable in function and is capable of positioning the stapling margin.

Description

technical field [0001] The invention relates to stationery, in particular to a stapler capable of pressing holes. Background technique [0002] Ordinary staples need to be bent during the binding process, so hard materials cannot be used. When binding some thicker and harder paper, the stapler will be bent or jammed due to insufficient hardness of the staples, resulting in Could not staple. At this time, it is very troublesome to first press the holes with the help of a separate hole press and then bind them. In order to solve this problem, some designs have appeared, such as the Chinese patent, the integrated stapler for pressing holes and binding with the publication number of 2794838. The functions of pressing holes and binding are realized by adjusting the positions of the transposition mechanism, but the structure for realizing its functions is complicated. . Chinese patent, publication number is a kind of stapler of 201143803, realizes the pressing hole function by ...

In order to solve this problem, some designs have appeared, such as the Chinese patent, the integrated stapler for pressing holes and binding with the publication number of 2794838. The functions of pressing holes and binding are realized by adjusting the positions of the transposition mechanism, but the structure for realizing its functions is complicated.

Chinese patent, publication number is a kind of stapler of 201143803, realizes the pressing hole function by the stapler that is installed on the pressing handle, the advantage is that the structure is simple, but the stapler of this design overlaps with the outlet hole of the staple, and the function Interfering with the structure, it is difficult to implement. In addition, the design only has a pair of staple holes on the base, and the bending groove is canceled, so that the staples cannot be bent and cannot be bound during binding.
