[0006] Optionally, the connection hole is an arc-shaped hole.

[0007] Optionally, an arc-shaped groove is further provided on a surface of the nut away from the first component, and the connection hole is located in the arc-shaped groove so that the screw head of the screw can be received in the arc-shaped groove.

[0008] Optionally, the numbers of the arc-shaped groove and the arc-shaped hole are both two.

[0009] Optionally, a through hole is formed in the second component, the stud is inserted into the through hole, and a threaded connection hole cooperating with the screw is provided on a surface of the second component close to the nut.
