Office binding machine

Abstract

The invention discloses an office binding machine which structurally comprises a workbench, a cutter, a machine head, a punching frame and a limiting structure. The cutter is installed at the side endof the workbench, the machine head is vertically installed at the upper end of the workbench, the punching frame is embedded into the inner side of the machine head, the limiting structure is horizontally installed at the upper end of the workbench, and the limiting structure comprises a bottom groove, a limiting plate, a movable groove and a movable rod; and the bottom groove is sunken in the inner side of the workbench, the limiting plate is horizontally arranged above the bottom groove, the movable groove is embedded in the inner side of the workbench, the movable rod is embedded in the inner side of the movable groove, the spring is arranged between the movable rod and the movable groove, and the upper end of the movable rod and the lower end of the limiting plate are fixed. Accordingto the office binding machine, the limiting structure is installed at the upper end of the workbench, so that the limiting structure adapts to page files, and the moving area is reduced, so that drilling is better conducted, and displacement is prevented; and an adaptive block is arranged on the front surface of a plate body, so that the contact area with the page files is increased, the stress during drilling is increased, and the stability during drilling is ensured.

Description

technical field [0001] The invention belongs to the office field, and in particular relates to an office binding machine. Background technique [0002] In order to organize the documents such as book pages, in order to ensure the neat arrangement of these documents and the convenience of reading, these book page documents need to be bound, and there are various methods of binding, including single-hole binding, and then need to use To the office binding machine, these office page files are bound and arranged, but there are following deficiencies in the prior art: [0003] Since the single-hole binding is to drill the corners of the page files, and the corners will form a span to the bottom groove, so that the contact area across the two ends of the bottom groove is different, and then when the pressure is drilled, the Along with the direction of its force, it drives the corners with smaller contact area to move to the bottom groove, resulting in inclined drilling, which aff...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an office binding machine to solve the problem in the prior art that the single-hole binding always drills the corner ends of the page files, and the corner ends will form a bottom-to-bottom The crossing of the groove makes the contact area across the two ends of the bottom groove different, and then when the downward pressure drilling is performed, the corner with the smaller contact area will be driven to move to the bottom groove according to the direction of its force, resulting in inclined drilling , a problem that affects the binding of book pages
