Multi-size rotating automatic punching device

Abstract

The invention provides a multi-size rotating automatic punching device. A to-be-stapled document is folded in two in the vertical direction in which the document is to be stapled, is placed on a base and is located between two elastic pieces, a circular top is pressed, two holes are punched in corresponding positions of the document folded in two, and one end of a stitching line penetrating the through holes is held by hand; and then, the pressed circular top is gradually released so that a needle head can be disengaged from the holes of the document, the document folded in two is opened, and the two ends of the stitching line are tied in the direction in which the document needs to be stapled. According to the multi-size rotating automatic punching device, by arranging springs, automatic opening and closing of a pressing plate are achieved; the stitching line is arranged at the bottom end of the needle head, and needle-free document stapling is achieved; by arranging a motor, rotating book stapling is achieved, and punching is facilitated; the detachable design is adopted for the needle head, and holes of different hole diameters can be punched; and by means of the device, the bookbinding efficiency is greatly improved, meanwhile, use of iron needles is reduced, and life is facilitated for people.

Description

technical field [0001] The invention belongs to the field of staplers, in particular to a multi-size rotary automatic puncher. Background technique [0002] The existing commonly used stapler must be equipped with staples, which not only needs to be stapled with iron wire, but also brings trouble to the destruction of expired confidential documents or materials after binding. With the development of science and technology, there are more and more documents or materials that need to be destroyed after use. As a good supporting tool for document shredders, the stapler without staples is becoming more and more necessary, and it will also become a tool for people to work and study One of the indispensable stationery supplies. Contents of the invention [0003] In view of this, the present invention aims to propose a multi-size rotary automatic puncher to provide a staple-free stapler with simple structure and easy use. [0004] In order to achieve the above object, technical...
