A handle of the hole punch apparatus pivots about a pivot rod, which handle front end is linked to the punch pin via the jam release clip. Pressing down on the handle advances the punch pin to cut a hole in a paper stack held inside a paper slot, and lifting up on the handle withdraws the punch pin out of the paper stack.
