[0029] The end of the driving disc 1 is connected with the protector 2, the end of the protector 2 is fixed with the extension plate 6, the diameter of the circle surrounded by the extension plate 6 is smaller than the diameter of the inside of the driving disc 1, and the top of the extension plate 6 is provided with the ball 7, the ball 7 can roll on the surface of the extension plate 6.

[0030] The surface of the protector 2 is fixed with the butt joint groove 5, the diameter of the butt joint groove 5 is consistent with the diameter of the butt joint ring 14 in the inside of the driving disc 1, the extension plate 6 is provided with a plurality of grooves 4 at intervals, the fixed plate 8 is arranged in the groove 4, the surface of the fixed plate 8 is fixed with two groups of plug-in blocks 10, the inner wall of the protector 2 is fixed with the extension block 13, the surface of the extension block 13 is provided with the moving groove 11, the plug-in block 10 is plugged into the moving groove 11, and the plug-in block 10 can move in the moving groove 11, when the end of the protector 2 is located in the inside of the driving disc 1, the plug-in rod 22 can be screwed into the screw hole 9 on the surface of the fixed plate 8, the surface of the driving disc 1 is fixed with the fixed frame 17, the plug-in rod 22 moves in the through hole 23 under the pulling of the reset locking spring 18, with the rotation of the driving disc 1, the screw hole 9 is aligned with the plug-in rod 22, the plug-in rod 22 can be plugged into the screw hole 9, the end of the plug-in rod 22 is not provided with a thread, so that the plug-in rod 22 can be smoothly plugged into the screw hole 9, by screwing the plug-in rod 22, the plug-in rod 22 is screwed in the screw hole 9.

[0031] The fixed plate 8 moves with the plug-in block 10, and a pulling adjustment spring 12 is provided in the moving groove 11. One end of the pulling adjustment spring 12 is connected to the surface of the plug-in block 10, and the other end is connected to the inner wall of the moving groove 11. The pulling adjustment spring 12 has a pulling force on the plug-in block 10, so that the plug-in block 10 is close to the inner wall of one end of the moving groove 11. By screwing the plug rod 22, the plug rod 22 is screwed into the screw hole 9, and due to the screw connection of the plug rod 22, the plug-in block 10 on the surface of the fixed plate 8 moves in the moving groove 11, the driving disk 1 is located outside the casing 2, and the fixed plate 8 is close to the inner wall of the driving disk 1.

[0032] After the driving disc 1 is lowered, the limiting ring 3 covers the top of the protective tube 2. Since the surface of the limiting ring 3 is arc-shaped, the driving disc 1 is squeezed by the limiting ring 3 during the descending process, so that the protective tube 2 swings to the bottom of the driving disc 1. The surface of the extension plate 6 is provided with a ball 7, which can reduce friction. After the protective tube 2 is located inside the driving disc 1, it is supported on the surface of the telescopic ring 15, so that the telescopic ring 15 is inserted into the insertion groove 16. The pushing spring in the insertion groove 16 is compressed, and the telescopic ring 15 is no longer supported on the end of the plug rod 22. The plug rod 22 moves in the through hole 23 under the pull of the reset locking spring 18. As the driving disc 1 rotates, the screw hole 9 is aligned with the plug rod 22, and the plug rod 22 can be inserted into the screw hole 9. There is no screw at one end of the plug rod 22. The groove makes the connecting rod 22 able to be smoothly inserted into the screw hole 9. By screwing the connecting rod 22, the connecting rod 22 is screwed into the screw hole 9, and due to the screw connection of the connecting rod 22, the connecting block 10 on the surface of the fixed plate 8 moves in the moving groove 11. In the normal state, the fixed plate 8 is pulled by the pulling adjustment spring 12 and is close to the center position of the casing 2. After the connecting rod 22 is screwed, the fixing plate 8 is close to the driving disk and the fixing plate 8 is away from the center of the casing 2. In this process, since the width of the fixing plate 8 is smaller than the width of the slot 4, there is a movable gap, and the connecting block 10 has a certain degree of freedom when moving in the moving groove 11, which enables the fixing plate 8 to automatically adjust its position to compensate for the angular deviation that may occur in the installation process of the casing 2. This automatic adjustment function ensures that even if there is a slight deviation in the installation angle of the casing 2, the fixing plate 8 can still fit tightly against the inner wall of the driving disc 1, thereby achieving stable docking of the driving disc and the casing 2 through the fixing plate 8, and the inner wall of the driving disc 1 is provided with a docking ring 14, and the surface of the casing 2 is provided with a docking groove 5, which can fit tightly against the surface of the docking ring 14. Since the diameter of the top of the casing 2 is smaller than the inner diameter of the driving disc 1, no friction is generated, which facilitates the position adjustment between the driving disc 1 and the casing 2, thereby achieving precise docking between the two.
