ABSTRACT:
A stapler assembly frame arranged to be associated with a common office stapler to form a complete assembly, the frame being composed of a pair of two-armed levers pivotally connected at a location between the arms of each lever in the manner of scissors. In the region of their pivot axis one scissors lever is provided with a passage opening through which passes the other scissors lever and the levers provide a fulcrum for each other in the region of the passage opening. The passage opening is dimensioned so that the rear, or pivot, end of the office stapler can be accommodated therein.
