Abstract

The invention discloses a hole puncher for paper punching, and relates to the field of hole punchers. The hole puncher for paper punching comprises a vertical plate, a cover plate, a cutter fixing plate, a clamp, a base plate and a waste material box which are sequentially arranged from top to bottom, wherein the cover plate and the vertical plate are in up-down slipping connection; the cutter fixing plate is fixedly connected with the cover plate; and the base plate is connected with the clamp. The vertical plate is provided with a driving device used for driving the cover plate to slide. A cutting tool is arranged inside the cutter fixing plate in a penetrating mode. The clamp comprises a mounting plate which is fixedly connected with the base plate, a gear arranged inside the mounting plate in a rotating mode, a first baffle arranged on the mounting plate in a left-right sliding mode, and a second baffle arranged on the mounting plate in a left-right sliding mode. The axis of the gear is arranged in the up-and-down direction. The first baffle and the second baffle are oppositely arranged and are both provided with racks engaged with the gear. According to the hole puncher for paper punching, the gear is arranged to be engaged with the racks of the first baffle and the second baffle, when one of the baffles moves, the other baffle can be driven to move under the engaging action, and the effect of automatic centering in the paper positioning and clamping process is achieved.

Description

technical field [0001] The invention relates to the field of hole punchers, in particular to a hole puncher for paper punching. Background technique [0002] In the file management work, the binding of files is a very important task. When binding files, you need to select the binding method as required, and then perform punching and binding. File punching is usually done by hand using tools. When the number of pages of the file to be bound When there are too many or a large amount of binding, manual punching is very laborious, and punching is easy to crack, which greatly increases the work intensity of the file management personnel, and some files require hole spacing standards when punching holes, which requires manual punching. First use a ruler to measure the marks and then punch the holes. The binding is cumbersome and the efficiency is low. The punched holes are easy to be irregularly bound, which affects the appearance of the binding. Although there are some electric p...
