ABSTRACT:
A punching device is provided that includes a frame disposed on a base and a pair of wall members, a lever having one end pivotally coupled between the wall members, a block slidably retained between the wall members by two plates and having an upper end linked to the lever a recess formed in the block, and a rod having an upper end fixed to the block and including a bore in communication with the recess of the block. The rod is movable downwardly by the lever to punch holes in paper, and provision is made for the residual of the paper to move through the bore of the rod, through the recess of the block, and into an access with a removable cover. A downwardly biased foot presses against the sheet materials on the base before the rod punches through the sheet materials. The base includes two interconnected support racks which are simultaneously adjustable.
