A first magnetic block 11 is fixedly installed on one end of the pin 10. An adjusting threaded rod 12 is rotatably installed on the side of the limiting moving plate 9 away from the pin 10. A fixing post 13 is fixedly installed on the surface of the wisdom tooth 2. A slot 14 is opened on the surface of the fixing post 13. A second magnetic block 15 is fixedly installed inside the slot 14. The fixing post 13 is adapted to the first slot 4, the second slot 5, the third slot 6 and the fourth slot 7. The pin 10 is adapted to the slot 14, so that the fixing post 13 can be inserted into the first slot 4, the second slot 5, the third slot 6 and the fourth slot 7, and the pin 10 can be inserted into the slot 14.
[0025] The positions of the first slot 4, the second slot 5, the third slot 6, and the fourth slot 7 correspond to far-center blocking, vertical blocking, near-center blocking, and horizontal blocking, respectively.
[0026] It should be noted that the limiting moving plate 9 is adapted to the first slot 4, the second slot 5, the third slot 6 and the fourth slot 7. The surface of the limiting moving plate 9 slides in contact with the inner surfaces of the first slot 4, the second slot 5, the third slot 6 and the fourth slot 7, which facilitates the stable movement of the limiting moving plate 9 within the first slot 4, the second slot 5, the third slot 6 and the fourth slot 7.
