Stripper for coated wires

Claim 1

A tool for removing insulation from electric wires having a pair of wire-holding members movable towards and away from each other, one of said wire-holding members having a wire-contacting surface with a V-shaped wire-receiving recess in a plane perpendicular to the axis of the electric wire held between said wire-holding members, said one wire-holding member having a side surface mounting a cutter knife, said cutter knife having a middle portion pivotally connected to said side surface of said wire-holding member, the other of said wire-holding members having a planar cable-contacting surface, an edge of said cutter knife being positioned at the intersecting point of the bisector of the vertical angle of said V-shaped recess and said planar cable-contacting surface of said other wire-holding member, said edge of cutter knife being elastically urged against the insulation of the wire inserted in an opening formed between said wire-holding members, a plane including the wire-contacting surface of said other wire-holding member and perpendicular to the bisector of said V-shaped recess of the wire-holding members linearly contacting the wire held between the wire-holding members in the direcion of axis of wire; said side surface of said one wire-holding member further including a rotatable eccentric cam with an operation knob; a rear end portion of cutter knife being elastically urged against said cam; an end surface of said eccentric cam, and said side surface opposite thereto of a wire-holding member having pin means and holes engaging and disengaging to optionally set the angular position of said eccentric cam to slidingly move in the direction in which said pin means engages said holes.
