The multi-core wire to be cut is passed through the guide sleeve on the support frame provided at the upper end of the support frame 1, and then placed between the two clamping blocks 2 on the workbench 3. Then, the output end of the motor 4 rotates to drive the bidirectional threaded rod 12 to rotate, while driving the two clamping blocks 2 to move in opposite directions to clamp and fix the wire. This avoids the displacement of the wire during the cutting process, effectively improves the quality of wire cutting, and improves the practicality and flexibility of the equipment.
