Punch is very useful in office life, mainly for make holes on the edge of papers. The current punch can only make holes, but not arrange them tidily. If we want a line of regular holes, we often need a punch of big scale. There is a control pole embedded in the base of this design, by which we can present regular holes with fixed distance or defined distance. It may serve as the role of professional punch to some extent. And it is helpful to our office life.
