For the above-mentioned objective, the present invention provides the perforating punch to file a stack of paper or a document, comprising a pressurizing unit (20), which is pressurized by an external force; a pressurizing fixing board (23) where the pressurizing unit (20) is combined; a rotation axis (22), which is combined with the pressurizing fixing board (23) to be rotated; multiple punch units (10), which can be perforated when the pressurizing unit (20) is pressurized; and multiple punch holes (51), into which the punch units (10) penetrate. The punch unit (10) comprises the female screw (12) and the multiple punch rods (11) combined with the female screw (12) so that the punch rods (11) can be replaced. Also, the supporter (40) includes the accommodation space (30) in order to accommodate the punch rods. |
