[0022] As a further improvement, a bearing 12 is provided at the connection between the fixed seat 6 and the rotating shaft core 7, and a positioning groove 13 is opened on the side wall of the rotating shaft core 7. By providing a bearing 12 at the connection between the fixed seat 6 and the rotating shaft core 7, the rotating shaft core 7 is facilitated to rotate in the fixed seat 6, and by opening the positioning groove 13 on the side wall of the rotating shaft core 7, the stability of the connection between the cutting head 8 and the rotating shaft core 7 is improved.

[0023] As a further improvement, a plug-in hole 14 is provided at the center of the cutting head 8, and a limiting protrusion 15 is provided on the inner wall of the plug-in hole 14. By providing the plug-in hole 14 at the center of the cutting head 8, it is convenient to connect the cutting head 8 with the rotating shaft core 7. In combination with the limiting protrusion 15 on the inner wall, the cutting head 8 can be easily axially slid while avoiding the cutting head 8 from rotating, thereby improving the stability of the connection of the cutting head 8.
