The adsorption unit 24 includes an adsorption member 241 for absorbing the fixed wing. The adsorption unit 24 is suspended on the turning member 22 and can move closer to or away from the loading platform 111 as the turning member 22 rotates. When the adsorption unit 24 is close to the object stage 111, the adsorption member 241 absorbs and fixes the wing plate placed on the object stage 111; The wing plate falls vertically into the positioning groove 112 under its own gravity.

The turning member 22 of this embodiment includes a link portion 221 and a mounting portion 222 . Wherein, the mounting portion 222 is formed by extending outward from the bottom of the connecting rod portion 221 near the side of the stage 111 , and the outer contour of the mounting portion 222 is roughly triangular.

In this embodiment, the top end of the link part 221 is suspended to the adsorption unit 24 , and the bottom end is fixedly connected to the power unit 23 . The mounting part 222 is rotatably mounted on the base 21 through the rotating shaft 224 , and a through hole through which the rotating shaft 224 passes is provided at a corresponding position of the mounting part 222 . In this embodiment, the rotating shaft 224 passes through the base 21 , and the axial direction of the rotating shaft 224 is parallel to the length direction of the stage 111 .

Further, an inwardly curved concave surface is formed between the installation portion 222 and the connecting rod portion 221 , so that the turning member 22 can accommodate the adsorption unit 24 . When the power-assisted turning mechanism 2 is in the non-working state, the adsorption unit 24 suspended from the top of the connecting rod portion 221 is accommodated in the turning member 22, so as to avoid interference between the adsorption unit 24 and other components of the power-assisted turning mechanism 2 or the longitudinal beam of the semi-trailer.
