Abstract
Wire-stripping pliers have outer clamping jaws and inner longitudinally movable stripping jaws. The stripping jaws are retracted, and the movable blade of a wire cutter is moved, by a pulling member in response to closure of the pliers handles. This movement is produced by a driving arm which moves along a cam surface on an extension of the pivoted clamping jaw, thereby pushing back the pulling member. The cam surface has a first portion of shallow inclination to provide rapid movement of the stripping jaws at low force, followed by a surface portion of steep inclination providing for relatively high cutting forces as the wire cutting blades close.
