Description

Technical Field

[0001] The present application relates to the technical field of hole punchers, and more specifically, to a paper hole puncher. Background Art

[0002] In an office, punching holes in paper is often necessary in clerical work, such as binding documents, materials, office paper, etc., such as loose-leaf paper, cards, test papers, albums, etc., sometimes need to be bound together after classification, and a stapler or a hole puncher is used for binding.

[0003] The document with the prior art publication number CN218659520U provides a new paper puncher. When punching holes in a batch of paper, the batch of paper can be manually stacked and aligned, and one of the groups of adjustment plates can be moved. Under the cooperation of the adjustment gear and the tooth groove, the two groups of adjustment plates are made to move synchronously on the carrier plate. After the batch of paper materials are laid flat on the carrier plate, one of the groups of adjustment plates is slid, and under the cooperation of the adjustment gear and the tooth groove, the two groups of adjustment plates are made to contact and squeeze the two sides of the paper materials, so as to limit the rectangular space of the paper materials, and punch holes by starting the hydraulic rod on the mounting frame. When adjusting the position of the paper materials, the carrier plate is directly slid left and right to slide in the adjustment groove, and holes can be punched on the paper materials by the punching knife, which not only ensures the neatness of the paper before punching, but also ensures the neatness of the hole positions of each group of paper. The multiple groups of hole positions of the punchable array are
