ABSTRACT:
A manual cable cutter includes a pair of fixed and shaking handles joined mutually in the upper part sides thereof, a spring for urging the pair of handles in the expanding direction, a fixed cutting blade disposed continuously in the upper part of the fixed handle, a turning cutting blade having a row of teeth formed on its arcuate outer face and having a basal end part turnably supported on the leading end part of the fixed cutting blade, a holdback claw rotatably disposed in the upper part of the fixed handle and adapted to be meshed by the spring with the row of teeth, a feeding claw rotatably supported on the shaking handle and adapted to be meshed by the spring with the row of teeth, a switch device for switching the range of motion of the shaking handle between a first opening position during the course of cutting motion and a second opening position during the course of releasing motion, and a release lever rotatably formed on the fixed handle for retracting the holdback claw and the feeding claw synchronously from the row of teeth toward the upper part of the fixed handle and rotated with the shaking handle. The switch device is switched to sway the shaking handle to the second opening position to cancel the engagement of the holdback claw and the feeding claw with the row of teeth.
