Wire stripper

A stripper for stripping covering from covered wire comprising:

• A cover head including a front plate formed with at least one inserting bore for passing the covered wire;
• a pair of cutter members each attached to a holder block and having cutter edges behind the inserting bore and arranged in the cutter head symmetrically on the opposite sides of the covered wire to be inserted therein, the pair of cutter members being pivotally movable and openable from aligned position toward the direction of insertion of the wire;
• a spring member retained on and interconnecting holder blocks to render the cutter members pivotally movable along paths symmetrical with respect to the wire and to urge the cutter members in closing direction when they are moved pivotally backward in the closing direction, at least one of said holder blocks projecting from the cutter head;
• a stationary grip of U-shaped cross section extending rearward from the cutter head and provided with a scale on an edge of its opening, and further including sliders disposed on a side of the wall cutter head and slidable along the wire by a gripping lever provided in opposing relation to the stationary grip, a pair of gripping jaws attached to the sliders respectively and opposing each other to permit passage of the wire therebetween and to grip the wire forwardly of the front plate and means for reducing the space between the opposing gripping jaws to cause the jaws to grip the wire when the sliders advance while moving the jaws away from the cutter members at the same time to pull the wire.
