Claim:
A wire-stripping plier comprising: automatic adaptation to various wire gauges and insulation thicknesses with two pairs of pivotable jaws of which the jaws of a first, outer pair are configured as gripper jaws ( 33 ) which are pivotable by means of a first jaw arm ( 1 ) and a jaw part ( 3 ) about a common pivot point ( 5 ), and the jaws of the other, inner pair that are configured as cutting jaws ( 41 ) with blades that cut into the insulation, and with a pull rod ( 43 ) attached to the cutter jaws ( 41 ) and longitudinally moveable within the jaw body providing the stripping motion that is coupled with a second plier arm ( 7 ) via a link ( 9 ), wherein at least one sliding wedge ( 13 , 23 ) is mounted in a recess shaped to match the sliding wedge ( 13 , 23 ) within the first plier arm ( 1 ) or in the jaw part ( 3 ), whereby a first sliding wedge ( 15 , 25 ) facing the cutting jaws is flat and a second sliding wedge ( 17 , 27 ) resting in the recess is so shaped that the separation between both sliding wedges at a central area of the sliding wedge ( 13 , 23 ) diminishes toward at least one of the two sliding wedge ends, and wherein squeezing the wire-stripping plier causes longitudinal displacement of the sliding wedge ( 13 , 23 ) along with simultaneous matching of position of the sliding wedge ( 13 , 23 ) perpendicular to the longitudinal direction that results in cutting-depth adjustment of the cutting jaws ( 41 ) and the cutting blade ( 37 ) attached to it.
