Abstract

An electric stapler capable of handling multiple sheets of paper. A motor-driven pair of wheel gears turn a swing arm having a symmetrical structure for driving a staple firing assembly and a clinch mechanism, thereby applying large pressure uniformly on staples. The clinch mechanism bends staple legs in different directions so that they do not overlap each other, preventing the clinched part of paper from increasing in the thickness of the stacked paper.
