  • Lever handled paper punch
    Publication number: 20080168874
    Abstract: A punch apparatus for punching holes through a paper stack. The apparatus has a rotationally attached lever handle. The lever handle has a handle end, a contact end, and a rotation axis between the handle end and the contact end. When a downward force is applied to the handle end, the lever handle rotates about the rotation axis. The contact end of the lever handle then exerts a force on a lever arm which in turn rotates a main shaft and attached pressure plate. As a result, the pressure plate exerts a punching force down on punch pins causing them to punch down through the paper stack.
