Abstract
A paper punch includes a base and a slide board is connected to the base. Multiple punch seats are located on the slide board and above the hole of the base. Each punch seat has a control member and a connection arm connected to the slide board. The control member is pivotably connected to the connection arm. The control member has an eccentric seat and an operation board. The eccentric seat is a cam and eccentrically connected to the connection arm. A first face is defined in the eccentric seat and located in opposite to the operation board. A second face is located adjacent to the first face. When switching the first face to the second face, the punch seat is movable along the slide board so as to obtain a desired distance between the punch seats.
