The two guide rods 3 are connected between the two connecting ends 2, and the end surface of the connecting end 2 is provided with a transverse square hole at the center of the lock hole. A guide sleeve 5 is sleeved on the guide rod 3 and can slide along the guide rod 3, and the cutting machine head 4 is hinged on the guide sleeve 5.

[0028] like Figure 5 , Figure 6 and Figure 7 As shown, the cutting head 4 and the guide sleeve 5 are hinged by a connecting piece, and a torsion spring 6 is wound on the gap between the connecting piece between the two sides of the cutting head 4 and the guide sleeve 5. The torsion spring 6 consists of three parts: a fixed end, a fixed rod and a support portion. The fixed end is formed by rotating a copper wire around the connecting piece, and there is a certain angle between the fixed end and the fixed rod to form a bent portion, and a U-shaped support portion extends from the bottom of the fixed end. Two notches 20 are provided on the top of the guide sleeve 5, which are respectively used to fix the fixed rods extending from the fixed ends at both ends. The cutting head 4 is used to connect the inner fixed support portion of the support arm of the cutting blade 18.
