摘要
A paper punch includes at least one punch head unit connected to a base and the at least one punch head unit has at least one punch head located therein. At least one resilient plate is cooperated with the at least one punch head. The first end of the at least one resilient plate is fixed to the at least one punch head unit and the second end of the at least one resilient plate is bent for form a connection end. An operation portion is connected between the first end and the second end of the at least one resilient plate. The connection end contacts a lower lateral side of a front pin extending transversely through the at least one punch head. The at least one resilient plate brings the at least one punch head upward after each punching action. The at least one resilient plate occupies less space and is easily installed. The paper punch is safe and easily assembled.
