Abstract:
A combination wire stripper comprising:a first pressure bar, said first pressure bar comprising a coupling portion at a rear end thereof, a downward open chamber at a front end thereof, a narrow, elongated cutter blade slot longitudinally disposed on the middle between the downward open chamber and coupling portion at said first pressure bar, and an arched guide slot near the coupling portion at said first pressure bar;a second pressure bar, said second pressure bar comprising a coupling portion at a rear end thereof pivoted to the coupling portion of said first pressure bar, an upward open chamber at a front end thereof facing the downward open chamber at said first pressure bar, a plurality of V-notches disposed on the middle between the upward open chamber and coupling portion at said second pressure bar, and a guide rod raised from one side wall thereof and inserted into the arched guide slot at said first pressure bar to guide relative movement between said first pressure bar and said second pressure bar;two wire stripping cutter assemblies respectively mounted in the downward open chamber at said first pressure bar and the upward open chamber at said second pressure bar for stripping the insulator of a two-line electric wire, said wire stripping cutter assemblies each comprising a fixed locating pin, two fixed blade jaws fixedly mounted on said fixed locating pin, a cutter blade fixedly connected between said fixed blade jaws, two movable wire clamping plates respectively mounted on said fixed locating pin at two opposite sides of said fixed blade jaws, said movable wire clamping plates each having an oblong sliding slot coupled to said fixed locating pin and a serrated portion for holding down a two-line electric wire, and two spring elements respectively supporting said movable wire clamping plates in the open chamber in said first pressure bar or said second pressure bar to push said movable wire clamping plates outwards;spring means connected between said first pressure bar and said second pressure bar to push said first pressure bar and said second pressure bar outwards from each other; andan elongated cutter blade fixedly mounted in the elongated cutter blade slot and moved with said first pressure bar against the V-notches at said second pressure bar for cutting the insulator of one-line electric wires of different diameters.
