The first limiting structure and the second limiting structure are elastically connected to the connecting guide block, and the lower end of the connecting guide block is fixedly connected with a first cutting head and a second cutting head. The first and second cutting heads are integrated in a staggered manner, and both adopt a right-angled cone shape. The second limiting structure is used to assist in the docking process. The rotating shaft rotates on the positioning shaft through a torsion spring, changing the position of the docking shaft sleeve and the arc-shaped limiting frame, so that the arc-shaped limiting frame and the groove on the connecting rod are locked together to prevent loosening.

[0005] Specifically, the second limiting structure includes a positioning shaft, a torsion spring, a rotating shaft, a docking bushing, and an arc-shaped limiting frame. The side end of the positioning shaft is elastically connected to the rotating shaft through the torsion spring.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. By installing the mating threaded sleeve, the lower end of the mating threaded sleeve is connected to the connecting guide block for easy support connection. The mating threaded sleeve is easy to connect with the installation shaft thread to achieve installation and mating work. The lower end of the connecting guide block is fixedly equipped with an inner sheath, a first cutting head, and a second cutting head, which facilitates cutting work when rotating. The staggered design of the first and second cutting heads can better improve the contact cutting surface and improve production efficiency.
