The inner walls of the threaded sleeves 25 are threadedly connected to the outer surfaces of the cross countersunk head bolts 26. The outer surfaces of the cross countersunk head bolts 26 penetrate through and are snap-fitted to the inner walls of the through grooves 11, and the through grooves 11 are opened on the four sides of the bearing body 1. The outer surfaces of the cross countersunk head bolts 26 are snap-fitted to the inner walls of the card slots 23, and the card slots 23 are opened on the four sides of the first dust-proof plate 21.

[0023] In this embodiment, the provided bearing body 1 can offer stable connection and self-rotation effects. The bearing body 1 can provide the effect of component engagement through the four connection slots 14 opened thereon. The provided dust-proof mechanism 2 can offer convenient installation and dust-proof effects. The second dust-proof plate 22 provides the effect of retaining the four connection blocks 24. And the bearing body 1 can provide the effect of positioning installation through the four connection slots 14 opened thereon. The four connection blocks 24 can be snapped into the connection slots 14 opened on the bearing body 1. The connection slots 14 can allow the threaded sleeves 25 connected to the connection blocks 24 to be snapped into them through the pipe slots opened on the top side. And through the provided threaded sleeves 25, the cross countersunk head bolts 26 can be threadedly connected to them by screwing. The bearing body 1 can allow the cross countersunk head bolts 26 to penetrate through the through slots 11 opened thereon and rotate freely therein. And the bottom side of the end of the cross countersunk head bolts 26 can be snapped into the card slots 23 opened on the first dust-proof plate 21. At this time, the cross countersunk head bolts 26 will make the first dust-proof plate 21 and the threaded sleeves 25 form a relative connection state. Since the threaded sleeves 25 are connected to the connection blocks 24 connected to the second dust-proof plate 22, at this time, the first dust-proof plate 21 and the second dust-proof plate 22 will be in a relative connection state. And a connection will be formed between the bearing body 1 and the first dust-proof plate 21 and the second dust-proof plate 22. At this time, the shaft bead connection part of the bearing body 1 can be covered between the first dust-proof plate 21 and the second dust-proof plate 22, so as to perform dust-proof treatment on it. And the slots opened in the middle of the first dust-proof plate 21 and the second dust-proof plate 22 will not prevent the bearing body 1 from making connections.

[0024] Embodiment 2

[0025] As Figures 1 - 4 shown, four anti-detachment blocks 27 are evenly and fixedly connected to the bottom side of the first dust-proof plate 21. The outer surfaces of the four anti-detachment blocks 27 are snap-connected to the inner walls of the inlet slots 12. The inlet slots 12 are all opened on the four sides of the bearing body 1. One side of each inlet slot 12 is provided with a sliding slot 13. The inner walls of the sliding slots 13 are all slidably connected to the outer surfaces of the anti-detachment blocks 27. One side of the anti-detachment blocks 27 is snap-connected to the inner wall of the anti-detachment slot 28. The anti-detachment slot 28 is opened on one side of the connection block 24. The inner sides of the first dust-proof plate 21 and the second dust-proof plate 22 are both joined and connected to the two ends of the bearing body 1.

[0026] In this embodiment, the first dust-proof plate 21 provides a retaining effect for the four anti-detachment blocks 27. The four anti-detachment blocks 27 can be snapped into the inlet groove 12 formed in the bearing body 1. One side of the inlet groove 12 is provided with a sliding groove 13 through which the anti-detachment block 27 can slide. During the sliding process of the anti-detachment block 27, the first dust-proof plate 21 connected thereto will rotate within a certain range. During the rotation of the first dust-proof plate 21 within a certain range, the card slot 23 formed therein will gradually approach the through groove 11 formed in the bearing body 1. When the anti-detachment block 27 is snapped into the anti-detachment groove 28 formed in the connecting block 24, the card slot 23 formed in the first dust-proof plate 21 will be in a state of being in communication with the through groove 11 formed in the bearing body 1. The provided anti-detachment block 27 can provide a guiding connection and anti-displacement effect. The first dust-proof plate 21 and the second dust-proof plate 22 will be placed at the ball connection provided at both ends of the bearing body 1 when they are connected through the components provided between them.

[0027] Working principle:

[0028] As Figures 1 - 4 shown, when it is necessary to disassemble and assemble the first dust-proof plate 21 and the second dust-proof plate 22, at this time, the connecting block 24 connected to the second dust-proof plate 22 is snapped into the connecting groove 14 formed in the bearing body 1. After the connecting block 24 is snapped in, the threaded sleeve 25 connected to the connecting block 24 will be synchronously snapped into the pipe groove provided on the top side of the connecting groove 14 formed in the bearing body 1. After the threaded sleeve 25 is snapped in, at this time, the anti-detachment block 27 connected to the first dust-proof plate 21 is snapped into the inlet groove 12 formed in the bearing body 1. After the anti-detachment block 27 is engaged with the inlet groove 12, at this time, the first dust-proof plate 21 is rotated within a certain range synchronously. During the rotation of the first dust-proof plate 21 within a certain range, the anti-detachment block 27 connected to the first dust-proof plate 21 will slide in the sliding groove 13 provided on one side of the inlet groove 12 formed in the bearing body 1. When the anti-detachment block 27 slides to a predetermined position, at this time, the anti-detachment block 27 will be snapped into the anti-detachment groove 28 formed in the connecting block 24, and the card slot 23 formed in the first dust-proof plate 21 will be placed at the through groove 11 formed in the bearing body 1. At this time, the through groove 11, the card slot 23 and the threaded sleeve 25 will be in a vertically communicating state. At this time, the cross-recessed head bolt 26 is inserted into the card slot 23 formed in the first dust-proof plate 21 and passed through the through groove 11 and then screwed. When the cross-recessed head bolt 26 rotates, it will gradually be threadedly connected to the threaded sleeve 25 connected to the connecting block 24. In the connected state, the first dust-proof plate 21 and the second dust-proof plate 22 will be placed on the top of the ball connection connected to the bearing body 1 and dust-proof treatment will be carried out on it.
