Cable cutter is a specialized for cutting cable scissors, two blades staggered, can be opened and closed. Cable cutter belongs to the large scissors, the use of "leverage principle" and "pressure and area inversely proportional to" design and become. In order to strengthen the strength of the cable cutter, convenience, cable cutter from the traditional manual cable cutter development of ratchet cable cutter, and then appeared hydraulic cable cutter, electric hydraulic cable cutter, all electric cable cutter.

Manual cable cutter manual cable cutter and ordinary scissors similar to the shape of a larger, longer grip (lever principle), the cutter is more rigid. Manual cable cutters can easily cut small cables and require a lot of hand strength for large cables.

Ratchet cable shears include grip device, cutting device and propulsion device, the shear pliers propulsion device is with the help of two gear drive to drive the activity of the knife body on the card teeth forward, so that the activity of the knife body and the fixed knife body of the blade part of the formation of the round part of the gradual narrowing of the efficacy of the shear, the gear is a tangential direction of the activity of the knife body on the gear, and make the gear with a plurality of the card teeth to promote the activities of the knife body The gear is to push the gear on the movable knife body in a tangential direction, and make the gear to push the movable knife body with a plurality of card teeth, so that the pushing force is dispersed in the card teeth, so that the card teeth are not easy to be damaged, in order to prolong its service life.

The hydraulic cable shear includes a fixture, characterized in that the fixture is processed with a card slot, a chain ring slot, a movable knife guiding groove and a static knife guiding groove, and a hydraulic cylinder with a flange is stuck in the card slot, and there is a plunger in the hydraulic cylinder body, and the left end of the movable knife is connected with the right end of the plunger through a return disk, and then the hydraulic cylinder body is stuck into the card slot of the fixture through its flange, the movable knife is put into the movable knife guiding groove of the fixture, and the static knife is put into the static knife guide groove of the fixture, the static knife into the static knife guide groove of the fixture. When used, the chain ring to be cut is firstly put into the chain ring groove, and then the cylinder body is injected with high-pressure liquid, under the action of liquid pressure, the plunger pushes the movable knife to move, and the static knife cooperates with it to form a shearing force to cut off the circular chain.
