During the movement of the side support 233 from the flattened state to the folded state relative to the positioning seat 251, the adjustment shaft 2511 moves from the first limit section 2335a to the second limit section 2335b; during the movement of the side support 233 relative to the positioning seat 251 from the folded state to the flattened state, the adjustment shaft 2511 moves from the second limit segment 2335b to the first limit segment 2335a.

When the side support 233 is in a flattened state with respect to the positioning seat 251, the extension section extends obliquely from one side of the side support 233 to the connection groove 2510 and in a direction away from the front surface of the side support plate 2331, and then extends obliquely in a direction closer to the front surface of the side support plate 2331; the adjusting groove 2335 extends along the extending direction of the extending section 2330, and opposite ends of the adjusting groove 2335 extend to the opposite ends close to the extending section 2330, respectively. It will be appreciated that after extending from the side support 233 in a first direction a length away from the side support plate 2331 and away from the front face 2513 of the nest 251, the extending length continues in the first direction a length away from the side support plate 2331 and toward the front face 2513 of the nest 251.
