[0026] The top surface of the second slider 104 is movably connected to two connecting rods 105 , and the two connecting rods 105 are movably connected to the two first sliders 102 respectively. When the second slider 104 moves, the two connecting rods 105 can push the two first sliders 102 to move in opposite directions.

[0027] A first electric push rod 106 is fixedly installed on one side of the interior of the base 1 , and an output end of the first electric push rod 106 is fixedly connected to the second slider 104 , and the first electric push rod 106 can push the second slider 104 to move.

[0028] A support plate 107 is fixedly mounted on the top surfaces of the two first sliding blocks 102 .

[0029] like Figure 3 As shown, a plurality of adjustment holes 401 are provided on one side of the outer surface of the lifting rod 4, and a fixing bolt 501 is movably connected to one side of the outer surface of the lifting sleeve 5. Inserting the fixing bolt 501 into the adjustment hole 401 can prevent the lifting sleeve 5 from continuing to lift.

[0030] A fixed rod 502 is fixedly installed on one side of the outer surface of the lifting sleeve 5 , a movable frame 503 is fixedly installed on one side of the fixed rod 502 , a rotating rod 507 is movably installed inside the movable frame 503 , and the rotating rod 507 can rotate inside the movable frame 503 .

[0031] The rotating block 504 is fixedly mounted on the outer surface of the rotating rod 507 , and the rotating block 504 can be rotated by rotating the rotating rod 507 .

[0032] A fixing sleeve 505 is fixedly mounted on one side of the rotating block 504 . When the rotating block 504 rotates, the fixing sleeve 505 can be driven to rotate so as to adjust the angle of the fixing sleeve 505 .

[0033] Rotating plates 508 are fixedly mounted on both ends of the rotating rod 507. When the rotating rod 507 rotates, the two rotating plates 508 can be driven to rotate.

[0035] It should be noted that the lifting rod 4 is fixedly connected to the support plate 107 , and when the support plate 107 moves, the two lifting rods 4 can be driven to move, so as to adjust the interval between the two lifting rods 4 .

When the plug block 302 is inserted into the slot 304, the two connecting holes 305 can overlap with the two mounting holes 306, and then, the external bolts are inserted to connect the plug block 302 with the connecting block 301, so as to facilitate the replacement of the placement blocks 303 with different curvatures.

[0039] The working principle of the utility model is as follows: the staff first places the bearing on the top surface of the placement block 303, then adjusts the height of the lifting sleeve 5, and rotates the fixing bolt 501 to fix the adjusted lifting sleeve 5, and then starts the first electric push rod 106 to push the second slider 104 to move. As the second slider 104 moves, the two connecting rods 105 can push the two first sliders 102 to move in opposite directions, so that the two support plates 107 drive the two lifting rods 4 to move in opposite directions to adjust the interval between the two fixed sleeves 505 until the two sides of the bearing are inserted into the two fixed sleeves 505, and then the second electric push rod 5051 can be started to push the fixing plate 5052 to move until the fixing plate 5052 clamps the two sides of the bearing, so that the bearing can be positioned and fixed.
