[0023] Further, referring to Figure 2 、 3 , first transmission part 8 is the internal thread of setting on the inner wall of positioner 3, and second transmission part 10 is the external thread of setting on the outer wall of positioner 3, and positioner 3 is connected between the pushing sleeve through internal thread and external thread.
[0024] Preferably, guide cylinder 7 is a hollow cylinder with open ends, and the end of positioner 3 is provided with a rotating ring 14.
[0025] Preferably, the guide rod is cylindrical.
[0026] In the above arrangement, positioner 3 is connected with guide cylinder 7 through threads, and when rotating positioner 3, positioner 3 moves towards or away from abutment end 5 under the action of threads, and when positioner 3 moves towards abutment end 5, the distance between them can be reduced, thereby exerting pressure on the shoulder joint for reset, and the position between positioner 3 and abutment end 5 is limited through the self-locking action of threads, thereby facilitating subsequent drilling.
[0027] Further, referring to Figure 5 , guide cavity 12 includes an arc-shaped passage 15 towards one end of guide roller 6, a vertical passage 16 adjacent to one end of guide cylinder 7, and a smooth transition between the arc-shaped passage 15 and the vertical passage 16; guide hole 13 is offset from the center of guide sleeve rod 11, and guide hole 13 is in communication with arc-shaped passage 15.
[0028] Preferably, the vertical passage 16 coincides with the center of the guide sleeve rod 11.
[0029] In the above arrangement, the positioning rod 3 is used to abut the shoulder joint to apply pressure to reset, and at the same time, can provide a positioning and guiding channel 9 for the drilling equipment. After drilling is completed, the guide sleeve rod 11 is inserted into the guide cavity 12, so that the end of the guide sleeve rod 11 can contact the abutting end 5 through the drilled bone tunnel. The guide wire passes through the vertical channel 16 and the arc-shaped channel 15 and is then out of the guide hole 13. Since the arc-shaped channel 15 has an arc and is in communication with the guide hole 13, the guide wire changes from a straight state to an arc-shaped state during movement. After the guide wire is out of the guide hole 13, the guide wire contacts the guide roller.
