ABSTRACT:
A staple remover has first and second levers having a distal end and a proximal end, in which the distal ends of the first and second levers are pivotally connected for rotation about an axis. The second lever has parallel walls and a pair of teeth upwardly projecting from top of the proximal end wall. Each tooth comprises a front wall and gradually down-sloped back portion. The back portion of each tooth is gradually sloped downward to push the disengaged staples toward the distal end of the first lever. The staple remover also includes a spring strip mounted on an inner surface of the first lever and biased with a wire connected to the second lever. The spring strip is made with a flexible metal. One end of the wire is connected to the spring strip and the other end of the wire is connected to the second lever around a pin so that when the first and the second levers are in a closed position with respect to each other, the spring strip is biased toward the wedging elements of the first lever. When the first and the second levers are in an open position, the spring strip is retracted toward the distal end of the first lever and engages and pushes the staple toward the distal end of the first lever. The first lever has parallel walls in which there is a groove longitudinally formed on an outside surface of each wall so that there are matching grooves on outer surface of the walls. The grooves are used to hold disengaged staples.
