[0025] In specific use, the movable rod 15 is pushed to slide into the detection sleeve 14, the pressure spring 16 is squeezed and deformed, and the outer ring of the bearing is sleeved from top to bottom with the fixed column 2, so that the three support blocks 5 are all located on the inner side of the outer ring of the bearing, and the knob 10 is turned to drive the adjusting screw 7 to rotate, and the adjusting screw 7 drives the adjusting block 8 to slide downward along the limit rod 20, and the adjusting block 8 drives the three pulleys 9 to slide downward along the inclined surfaces of the corresponding three sliders 6, pushing the three sliders 6 away from each other, squeezing the reset spring 21 to cause compression deformation, and at the same time the slider 6 pushes the slide rod 4 to extend outward along the slide hole 12, so that the support block 5 is against the inner wall of the outer ring of the bearing, so that the outer ring of the bearing is fixed to the outside of the fixed column 2 and is coaxially arranged with the fixed column 2, and the movable rod 1 is released. 5.
