Specifically, the end of the connecting portion 11 may be provided with a limiting component, the limiting component may be disposed on one side of the connecting portion 11 away from the supporting framework 3, and when the connecting portion 11 rotates to a preset position, the limiting component interferes with the adjacent connecting portion 11, so as to prevent the adjacent connecting portion 11 from rotating continuously. The limiting part can limit the rotation stroke between the adjacent connecting parts 11, and the excessive rotation of the adjacent connecting parts 11 is avoided.

Specifically, between two adjacent connecting portion 11, can set up the locking part to the relative position between the adjacent connecting portion 11 of restriction, thereby guarantee the stability of arc pole 1 structure, the steering wheel does not take place deformation when guaranteeing that the vehicle is gone, and then guarantees the security that the vehicle was gone.

Specifically, a resilient mechanism 12, such as a torsion spring or a spring, may be connected between each adjacent two of the connecting portions 11.

By arranging the rebounding mechanism 12 between two adjacent connecting parts 11, when the two ends of the arc-shaped rod 1 move towards the directions away from each other, the connecting parts 11 can be automatically unfolded under the acting force of the rebounding mechanism 12.

As shown in fig. 6, specifically, the length of the arc section of the side of each connection portion 11 facing the center of the tray body is smaller than the length of the arc section of the side of the connection portion 11 away from the center of the tray body.

That is to say, along the circumferential direction of steering wheel, the length that connecting portion 11 is located the inboard segmental arc of steering wheel is less than the length of the segmental arc in the outside to when making connecting portion 11 move to the direction of keeping away from the center of steering wheel, when moving to the biggest position of radian, the tip that is located the segmental arc in the steering wheel outside of adjacent connecting portion 11 butt each other, in order to prevent that connecting portion 11 from continuing to rotate to the direction of keeping away from the center of steering wheel, thereby guarantee that arc pole 1 can keep in predetermined maximum radian position department.
