[0034] In one embodiment of this utility model, the first locking foot 2a, the second locking foot 2b, and the locking base 1 are integrally formed.

[0035] In one embodiment of this utility model, the inner diameter of the card holder 1 is equal to the diameter of the annular card connector 4.

[0036] For reference Figure 5 As shown, in one embodiment of the present invention, the breakpoint 41 is a gap with a certain width formed by the complete break of the annular snap fastener 4, which allows the annular snap fastener 4 to contract and expand radially.

[0037] The working principle of the locking nut and locking pin assembly described in this utility model is as follows: Taking the connection between the hubcap and the hub as an example, first, the annular snap fastener 4 is placed inside the annular slot 31 of the nut 3. Then, the fixing nut 3 with the annular snap fastener 4 is embedded into the inside of the bracket 1, so that the first snap foot 2a is engaged with the annular snap fastener 4. Then, the snap spring 5 is placed at the port of the bracket 1 to increase the snapping force of the first snap foot 2a, thus completing the fixing of the nut 3 and the bracket 1. Finally, the side of the hubcap with the nut 3 is aligned with the connection hole of the hub, and then the hub and the nut 3 are fixed with bolts.
