Classification of cable cutters The cable cutter is a cutting pliers specially designed for cutting cables. The two blades are interlaced and can be opened and closed. Cable cutters are large scissors that are designed using the "lever principle" and "pressure is inversely proportional to the area". In order to strengthen the strength and convenience of cable cutters, cable cutters have developed ratchet cable cutters from traditional manual cable cutters, and hydraulic cable cutters, electro-hydraulic cable cutters, and all-electric cable cutters have emerged. Manual cable cutters Manual cable cutters are similar to ordinary scissors in that they have a larger shape, a longer grip (lever principle) and a harder blade. Manual cable cutters can easily cut off small cables, and large cables require a lot of hand. The ratchet cable cutter comprises a grip device, a shearing device and a propulsion device. The propulsion device of the shearing pliers is driven by two gears to drive the teeth on the movable knife body forward, so that the movable knife body and the fixed knife body The circular portion formed by the blade portion of the body is gradually reduced to achieve the shearing effect, the gear pushes the gear on the movable cutter body in the direction of the tangential line, and the gear is pushed by the plurality of latching teeth to push the teeth of the movable cutter body. Disperse the pushing force on the teeth, so that the teeth are not easily damaged to prolong their service life. The hydraulic cable cutter includes a clamp, wherein the clamp is formed with a card slot, a link groove, a movable knife guide groove and a static knife guide groove, and the cylinder has a hydraulic cylinder with a flange, and the hydraulic cylinder has a body The plunger, the left end of the movable knife is coupled with the right end of the plunger through the return disk, and then the hydraulic cylinder body is clamped into the slot of the clamp through the flange thereof, and the movable knife is placed in the movable knife guiding groove of the clamp, and the static knife is placed. Enter the static knife guide groove of the clamp. When in use, the chain to be cut is first placed in the chain ring groove, and then the high pressure liquid is injected into the cylinder body. Under the action of the hydraulic pressure, the plunger pushes the moving knife to move, and the shearing force is combined with the static knife to form a circular force. The chain is cut.
