Abstract:
Rotary cutting pliers comprising a first unit wherein a first bearing disk having a lower disk portion projects upward from a first handle and has a first insertion space for inserting a wire, that opens vertically upward from a rotary center of said first bearing disk and a second unit wherein a second bearing disk projects upward from a second handle and has a second insertion space for inserting a wire open upward and inclined from a rotary center of said second bearing disk; said first and second units are axially joined to each other at their respective rotary centers and a rotary disk having a toothed ratchet on the circumference and having a third insertion space open from the rotary center is incorporated between both bearing disks of the joined units; a first curved cutter is formed in insertion space of first bearing disk and a second curved cutter is formed from the rotary center in said third insertion space of rotary disk; a feed pawl on said second unit feeds said ratchet in angular increments and has a tripper for retaining the rotary disk in a predetermined position; a fixed pawl on said first lower disk portion has an end that interlocks with said feed pawl; and a trip lever mounted on first handle releases said fixed pawl from said ratchet teeth so as to stop the rotation of the rotary disk; a belt is fixed on said rotary disk and turns said rotary disk in a direction reverse to the rotation of said ratchet; an outer spring is connected to said belt and a push arm located on an inner leg of second handle, is configured so as to travel in an interlocking relationship with a pulley fixed to the middle portion of said belt, having a pushing end to push up said tripper on said feed pawl and to release said feed pawl from the teeth of said ratchet; a stopper port is mounted on an upper portion of inner spring to pull said push arm downward when a stopper mounted on an inner leg of first handle is removed from said stopper port.
