[0024] In this embodiment: Rotating the screw 406 drives the arc-shaped toothed plate 405 to rotate, and the arc-shaped toothed plate 405 drives the scroll plate 404 to rotate. When the scroll plate 404 rotates, it drives multiple groups of sliders 402 to move towards the central position of the placement rack 4. The slider 402 drives multiple groups of placement blocks 403 to move towards the central position of the placement rack 4. The gap between the placement blocks 403 is adjusted to adjust the size of the bearing to be placed. By adjusting the gap between the placement blocks 403, the positioning shaft 102 is clamped to a certain extent to prevent the positioning shaft 102 from rotating.

[0025] Please refer to Figure 1 , 2, 3. One end of the top of the bottom plate 1 is fixed with a fixing column 101. At the top outside the fixing column 101, there is a fixing block 104. One end of the fixing block 104 is slidably connected with a toothed groove column 2. One end of the toothed groove column 2 is provided with an engaged toothed rod 203. At the bottom of the toothed groove column 2, there is a pressing block 201. Outside the toothed rod 203, there is a handle 204. At the top outside the toothed groove column 2, there is a spring 202.
