[0036] Further, such as Figure 4 As shown, a rubber ring 9 is fixed to the top of the limiting ring 15; when in use, the rubber ring 9 can provide a buffer when the sliding sleeve 13 falls, thereby protecting the sliding sleeve 13 and reducing damage.

[0037] Working principle: when in use, the staff can rotate the screw rod 22, and the threads at both ends of the screw rod 22 are in opposite directions, so as to drive the two threaded seats 23 and the clamping seat 24 to move, and then clamp them to the guide column through clamping, so as to fix the mounting structure on the guide column, so as to position the sliding sleeve on the mounting seat 21 under the guide column, wherein the sliding sleeve is inserted into the through hole at the bottom of the mounting seat 21 for fixing, and the vertical rod 11 is used to guide the upward movement of the sliding sleeve 13, and the sliding sleeve 13 of the bearing 74 is installed on the guide column by pulling up the sliding sleeve 13, and the mounting seat 21 and the sliding sleeve 13 are detachably connected, so as to facilitate the staff to replace different mounting seats 21 to adapt to different sliding sleeves, and the staff can drive the rotating shaft 31 by rotating, so as to drive the rope wheel 32, and the rope wheel 32 reels the pull rope 33 to lift the sliding sleeve 13, so as to drive the sliding sleeve 13 and the sliding sleeve to move upward, so that the sliding shaft The sleeve is installed on the guide column, which is convenient for the staff to use. By pulling the sleeve 43, the fixation on the top of the ball is released, and then the jack of the fixing rod 41 and the plug rod 42 are connected, the ball is inserted into the inside of the slot 45, and then the sleeve 43 is pushed. The sleeve 43 is sleeved on the outer surface of multiple balls to limit them and fix them. The positioning pin 101 and the positioning hole 102 are used to improve the accuracy. By relying on the above-mentioned detachable structure, it is convenient for the staff to replace different supports 14, so that it is convenient for the staff to use; because the surface of the guide column is smooth, the clamp seat 24 is prone to sliding, and the clamp seat 24 is clamped too tightly, which may cause the surface of the guide column to be damaged. Therefore, by providing a groove 61 and a rubber strip 62, the rubber strip 62 can be sunken into the groove 61, so that the side wall of the clamp seat 24 is in contact with the guide column and fixed, and the rubber strip 62 enhances the friction with the surface of the guide column, thereby achieving a fixing effect;

[0038] The oil suction wheel 72 is preferably installed on the fixing seat 73 of the fixing member 74 so as to be able to wipe the surface of the guide column more conveniently.
