[0049] Working principle:

[0050] The copper wire wound on the copper wire tray 2 is passed through the copper wire guide hole 302 and then clamped between the upper pressure wheel 12 and the lower guide wheel 11. The copper wire tray 2 starts to rotate to drive the copper wire to move forward.

The second gear 26 rotates and drives the cutting knife 18 to rotate toward the copper wire through the second connecting rod 25. The cutting knife 18 cuts the copper wire, and the feeding spiral 34 transports the cut copper wire forward.
