Labor-saving punching machine

Abstract

The invention relates to a labor-saving punching machine. The labor-saving punching machine is characterized in that the labor-saving punching machine comprises a base, an operation assembly, a connecting assembly and one or more punch assemblies; and the operation assembly is in pivoted connection with the base in the mode of rotating relative to the base, one end of the connecting assembly is correspondingly connected to the operation assembly, the other end of the connecting assembly is arranged on the base in a pivoted mode, and the one or more punch assemblies are arranged on the base andconnected to the connecting assembly. According to the labor-saving punching machine, the operation assembly and the connecting assembly are connected to the same side of the base in a pivoted mode,the one or more punch assemblies are connected to the middle of the connecting assembly, the operation assembly can drive the connecting assembly to further drive the one or more punch assemblies to conduct punching, the operation assembly, the connecting assembly and the punch assemblies are mutually matched, thus the large punching stoke can be achieved, paper with the large number of sheets canbe punched, and the labor saving effect is also achieved.

Description

technical field [0001] The invention relates to a punching machine, in particular to a labor-saving punching machine. Background technique [0002] Existing punching machines are mainly used to form holes on documents to facilitate book making and storage. Due to the limited linear travel of the punches of punching machines, various labor-saving punching machines on the market have achieved this through various structural improvements. The purpose of making the punch more labor-saving. [0003] For example, the Chinese publication number CN102101304 invention application discloses a punching machine structure, which mainly drives the punching parts to punch holes through the linkage of the first pressing arm and the second pressing arm, wherein the first pressing arm and the second pressing arm The fulcrums of the arms are all pivotally connected to the seat frame, and the first pressing arm is connected to the second pressing arm at a resistance point, so that when the pun...

AI Technical Summary

Problems solved by technology

[0010] In order to solve the problem of insufficient punching distance and poor labor-saving effect caused by the configuration of the fulcrum, force-applying point or force-resistance point of the existing punching machine lever, the main purpose of the present invention is to provide a labor-saving punching machine , through the configuration adjustment of the lever position, when the operation component is matched with the connection component, a larger punching distance can be generated, thereby achieving the effect of labor saving and high-number paper punching
