ABSTRACT:
A punch includes a first member and a second member which has two lugs extending therefrom which are pivotally connected to the first member. Two apertures are defined through the second member. A transverse frame is connected between the two lugs and two punching tools movably extend through the transverse frame. Each punching tool has the first end thereof contacting the underside of the first member and the second end of each punching tool extends through the transverse frame and is located in alignment with the aperture corresponding thereto. A first end of a rod rotatably extends through the second member and the first member, wherein a second end of the rod movably extends through the second member. A handle is pivotally connected to the first end of the rod so that the handle is pivoted relative to the first member to extend the distance between the punching tools and the handle.
