In this embodiment, the limiting protrusion 13 extends from the outer peripheral wall of the shaft body 12, that is, the limiting protrusion 13 is designed in one piece with the shaft body 12, and rotates with the shaft body 12. The bottom of the limiting protrusion 13 is connected with the shaft body 12, and the top surface of the limiting protrusion 13 is an outwardly convex arc surface. The limiting protrusion 13 is similar to a cam structure and has an arc segment profile. The arc segment profile of the limiting protrusion 13 forms two symmetrical arc segments with the vertex as the center point. During the rotation and floating of the first seat body 11, the limiting protrusion 13 also rotates, and the arc segment profile of the limiting protrusion 13 always abuts against the limiting structure of the second seat body 21. In this way, the first seat body 11 and the second seat body 21 do not form a loose floating hinge. In particular, when the first seat body 11 is rotated to an angle of 90 degrees with the second seat body 21, the first seat body 11 and the second seat body 21 do not interfere with each other.
