The rotation of the driven bevel gear 303 rotates the No. 1 screw 302. The outer surface of the No. 1 screw 302 is threadedly connected with a movable plate 306. The rotation of the No. 1 screw 302 can move the movable plate 306 meshing with it to the side close to the bearing body 1. Clamps 307 are fixed on the opposite sides of the movable plates 306 at the left and right ends. The movement of the movable plate 306 can move the clamps 307, thereby causing one side of the clamps 307 to contact the bearing body 1, and then the other driving rods 305 are rotated in turn, so that the four clamps 307 clamp the bearing body 1, so that the bearing body 1 can be positioned and fixed.

[0025] The cross-sectional shape of the fixed cavity 301 is L-shaped, the inner top wall and the inner bottom wall of the fixed cavity 301 are both fixed with sliding bars, and the top and bottom of the movable plate 306 both perform horizontal linear motion in the inner cavity of the sliding bars.

[0026] In this embodiment, anti-skid pads are fixed on the opposite sides of the left and right end clamps 307. The anti-skid pads are rubber pads. The anti-skid pads are used to increase the friction between the clamps 307 and the bearing body 1. Through holes are opened on the upper and lower ends of the opposite sides of the two positioning rings 2. The size of the inner cavity of the through hole is larger than the size of the clamp 307.

[0027] It should be noted that, through the cooperation between the fixing mechanisms 3 , the clamping plate 307 can be driven to fit and contact one side of the bearing body 1 , so that the bearing bodies 1 of different sizes can be fixed.

[0028] See also Figure 4In order to fix the two positioning rings 2, the connecting mechanism 4 in this embodiment includes a mounting block 401 fixed on the upper and lower surfaces of the positioning ring 2. The left mounting block 401 is threadedly connected to a No. 2 screw 402 with one end penetrating and extending to the opposite side of the two mounting blocks 401.

[0030] The working principle of the above embodiment is:

[0031] (1) When fixing the bearing body 1, first, put the two positioning rings 2 on the left and right ends of the outer surface of the bearing body 1, and then rotate the driving rod 305. The rotation of the driving rod 305 rotates the active bevel gear 304, and the rotation of the active bevel gear 304 rotates the driven bevel gear 303 meshing with it. The rotation of the driven bevel gear 303 rotates the No. 1 screw 302. The rotation of the No. 1 screw 302 can make the movable plate 306 meshing with it move toward the side close to the bearing body 1. When the movable plate 306 moves, its top and bottom both move in the inner cavity of the slide bar, which can limit the movement of the movable plate 306. The movement of the movable plate 306 can move the clamping plate 307, thereby causing one side of the clamping plate 307 to contact the bearing body 1. Then, rotate the other driving rods 305 in turn, so that the four clamping plates 307 clamp the bearing body 1, so that the bearing body 1 can be positioned and fixed.

[0032] (2) In order to fix the two positioning rings 2, the No. 2 screw 402 can be rotated. The No. 2 screw 402 rotates in the inner cavity of the left-end mounting block 401 and moves to the right until the other end of the No. 2 screw 402 is screwed into the mounting groove 403 opened on the left side of the right-end mounting block 401, so that the two mounting blocks 401 can be fixed, thereby fixing the two positioning rings 2, thereby improving the stability of the fixed bearing body 1.
