[0012] The U-shaped rod is inserted and slidably connected with the I-shaped plate through the through hole.

[0013] Preferably, one end of the telescopic spring abuts against the limiting ring, and the other end of the telescopic spring abuts against the I-shaped plate.

[0014] The position adjustment between the cutting mechanism and the I-shaped plate can be coordinated through the elastic expansion and contraction of the expansion spring.

[0015] Preferably, the cutting assembly includes a connecting rod, a connecting shell fixed to one end of the connecting rod, a rotating rod rotatably connected to the connecting shell, a mounting plate sleeved and fixed on the wall of the rotating rod, and a cutting wheel plugged into the wall of the rotating rod.
