The upper wing plate 24 is located above the lower wing plate 21 and is provided corresponding to the lower wing plate 21. The web 23 is located the lower pterygoid lamina 21 both sides, and web 23 upper and lower both ends are connected respectively in lower pterygoid lamina 21 and upper pterygoid lamina 24 edge, and web 23 tip and lower pterygoid lamina 21 parallel and level.

In order to bind the movable plate layers 111 with the movable plates 1114, two parallel binding ropes 1112 are arranged in front of and behind the movable plate layers 111, a plurality of round holes are tied on each binding rope 1112 at intervals, and two ends of the first pin shaft 1111 simultaneously penetrate through the round holes arranged at corresponding positions on the two parallel binding ropes 1112 to form the movable plate layers 111. Further, the tying rope 1112 may be a nylon rope, so that the first pin 1111 may be a stepped shaft in order to avoid slipping off the first pin 1111 from the circular hole, and the first circular hole may be fixed with the first pin 1111 by gluing. To this end, a plurality of movable plates 1114 are combined in a row to constitute the movable plate layer 111. When the turn-around box body 2 contacts the movable plate layer 111, the movable plate 1114 thereon receives the box body pressure, the movable plate 1114 can rotate around the first bolt 1111 by a certain angle, and the movable plate 1114 thereon can be more attached to the shape of the turn-around box body 2 in the process of pressing down the movable plate layer 111, thereby ensuring the attaching degree between the turn-around box body 2 and the cross beam 11. Further, the width of the movable plate 1114 may be appropriately adjusted according to actual production needs, and the larger the number of movable plates 1114, the closer the shape of the movable plate layer 111 is to the shape of the turn-around case 2 itself according to the principle of differentiation.
