S2, Cutting the sheath: The cable is conveyed forward by the support plate (3). The position of the movable blade (18) is lowered by rotating the cutting handle (15). The movable blade (18) is lowered to a position where it can cut the cable sheath. The cable sheath is cut open by the cutting of the movable blade (18) and the fixed blade (19). S3, Separating copper wires: By rotating the separation frame (5) through the separation handle (26), the rotating clamp (24) and the fixed clamp (30) clamp the copper wires in the cable. By rotating, the twisted copper wires are separated, and the cable continues to be transmitted, so that the copper wires on the cable are above the stop block (42). Since each copper wire is separated, the copper wires at both ends of the cable cross each other and are connected together. S4, Torsion Connection: By rotating the extrusion handle (34), the bidirectional threaded rod (35) drives the two transmission blocks (36) to move towards each other, driving the extrusion bar (41) and the pressure block (40), causing the pressure block (40) to descend and extrude the copper wire between the two stops (42), so that the copper wires that cross each other at both ends of the cable are tightly connected. By rotating the connecting frame (6), the copper wires that cross each other at both ends of the cable are twisted, and the two ends of the cable are connected together.
