The threaded sleeve 10 is rotatably installed inside the fixed cavity 8, and the threaded rod 11 is penetrated inside the threaded sleeve 10. One end of the threaded rod 11 is connected to one end of the cavity 6, and the other end of the threaded rod 11 extends to the inside of the connecting cavity 9. The outer wall of the threaded sleeve 10 is installed with transmission teeth 12, and a transmission gear 13 is installed on one side of the fixed cavity 8. The transmission teeth 12 and the transmission gear 13 are meshed with each other. The first servo motor 14 is installed at one end of the fixed cavity 8, and the output end of the first servo motor 14 is connected to the transmission gear 13. One end of the movable gear 13 is connected. When in use, the first servo motor 14 is started to drive the transmission gear 13 to rotate. Since the transmission gear 13 is meshed with the transmission teeth 12, the transmission teeth 12 are used to drive the threaded sleeve 10 to rotate under the limit of the limit groove 17 and the limit block 18. Since the threaded sleeve 10 is threadedly connected to the threaded rod 11, the threaded sleeve 10 is used to drive the threaded rod 11 to move under the limit of the limit rod 15 and the limit sleeve 16. Therefore, with the cooperation of the movable rod 19, the threaded rod 11 is used to drive the cavity 6 to move, and the cavity 6 and the rotating roller 7 are adjusted to appropriate positions. The positions of the cavity 6 and the rotating roller 7 can be adjusted.
