[0025] Example 1

[0026] like Figure 3 As shown, the bearing support part 1 includes a support part top 12 and a support part bottom 11, wherein the support part top 12 is connected to the support part bottom 11, the support part top 12 is in a truncated cone shape, and the support part bottom 11 is in a cylindrical shape, preferably a cylindrical shape. A support part through hole 13 is formed in the bearing support part 1, and the connecting member 5 is inserted into the support part through hole 13, so that the bearing support part 1 can slide along the connecting member 5, and an inwardly recessed support part accommodating cavity 14 is formed on the bottom surface of the support part bottom 11, and the support part through hole 13 is connected to the support part accommodating cavity 14, the upper end of the spring is in the support part accommodating cavity 14, and the spring 4 is in contact with the top surface of the support part accommodating cavity 14.

[0027] Example 2

[0028] like Figure 2 As shown, the base 2 is cylindrical, preferably cylindrical. The top of the base 2 is recessed inward to form a first base accommodating cavity 21. The shape and size of the first base accommodating cavity 21 are adapted to the shape and size of the bottom 11 of the support portion. The connecting member 5 is in the first base accommodating cavity 21. The spring 4 is sleeved on the outer periphery of the connecting member 5.

[0031] The utility model is used as follows: Figure 4 and Figure 5 As shown, when assembling the bearing, first place the outer ring 31 of the bearing on the top 12 of the support part, and then place the ball 32 on the inclined surface of the top 12 of the support part. Since the top 12 of the support part is in the shape of a truncated cone, its outer peripheral wall is in the shape of an inclined surface, and the ball 32 is supported in the angle formed by the inclined surface of the top 12 of the support part and the inner wall of the outer ring 31. Then place the inner ring 33 on the top 12 of the support part. Since the aperture of the inner ring 33 is smaller than the aperture of the outer ring 31, the inner ring 33 is above the outer ring 31. Then press the bearing support part 1 downward by hand so that The bearing support part 1 is gradually pressed into the first base accommodating cavity 21. During the pressing process of the bearing support part 1, the outer ring 31 will be held by the top edge of the base 5 and cannot move further downward. During this process, the ball 32 gradually moves to the inner wall of the outer ring 31. At this time, the inner ring 31 continues to be pressed down until the inner ring 33 and the outer ring 31 are engaged with the ball 32 between them. Finally, the retainer is inserted between the outer ring 31 and the inner ring 33 to complete the assembly. After releasing the hand, the bearing support part 1 is reset under the action of the spring 4, driving the assembled bearing to bounce up. For some bearings with larger and wider apertures, the outer ring 31 can be placed on the top surface of the lower layer of the step part 24, and a circle of gap is formed between the inner wall of the outer ring 31 and the upper layer of the step part 24. The ball 32 is placed in the gap, so that the ball 32 is in a suitable position in the inner wall of the outer ring 31. The inner ring 31 is placed on the bearing support part 1, and the bearing support part 1 is pressed down according to the above method to complete the assembly of the bearing.

[0032] From the above description, it can be seen that the utility model has a simple structure and is easy to use. It is easy to complete the sleeve assembly of the outer ring, inner ring and ball of the bearing, thereby completing the assembly of the bearing, avoiding the problem of the ball easily slipping during manual assembly, and making the sleeve assembly process of the bearing more convenient.
