[0081] The first limiting screw 14 located on the same side is detachably installed in the limiting hole 104 located on the same side. For reference Figure 3, the user pulls out the first limiting screw 14 on both sides, slides the limiting block on both sides away from the baffle 2, at this time the limiting block on both sides respectively drives the two movable blocks on the same side to move towards the middle of the horizontal plate of the u-shaped base 1, at this time the reset spring 15 on both sides is in a stretched state, at this time the first limiting screw 14 on both sides is inserted into the limiting block 13 on both sides respectively, and the reset spring on both sides is kept in a stretched state, then the two arc-shaped clamping plates 4 are fixed on the cable to be cut, at this time the relative position does not change, then the first limiting screw 14 on both sides is pulled out again, the reset spring 15 on both sides is still in a stretched state, and the restoring force is the tension on both ends of the cable to be cut 3, after the cable to be cut 3 is cut off in the subsequent work, the reset spring 15 on both sides starts to reset towards both sides, and drives the two sections of the cable 3 after cutting to separate, avoiding falling to the ground.
