When the cutting wire bypasses the thread on the adjusting shaft 702, it is offset under the action of the thread groove. When the adjusting shaft 702 rotates, the cutting wire moves on the surface of the adjusting shaft 702 under the action of the thread, thereby adjusting the tension of the cutting wire. A wire unwinding motor 11 and a tension display 12 are fixedly connected to the right side wall of the wire feeding mechanism 1, and the output end of the wire unwinding motor 11 is fixedly connected to the wire unwinding shaft 5. The tension display 12 is located in front of the wire unwinding motor 11.

The adjusting shaft 702 is conical and has a thread on the conical surface. The cutting wire passes around the thread groove.
