A punch includes a base with a base plate mounted thereto and a plurality of punch units are fixedly connected to the base plate by bolts. Each punch unit has a bottom plate and a casing which is connected to the bottom plate so as to define a receiving slot between the bottom plate and the casing. A punch member movably extends through the casing and a spring is mounted to the punch member such that a lower end of the punch member may extend through the casing, the receiving slot, the bottom plate and the base plate. Two positioning blocks extend from the bottom plate and are engaged with a connection hole defined in the base plate so as to prevent the punch unit from sliding or rotating relative to the base plate. A handle is pivotably connected to the base plate and has a plurality protrusions on an underside thereof such that the punch members are pushed by the protrusions.
