[0026] The side wall of the auxiliary structure 6 is fixed with one end of a folding component 623 through a rotating shaft component, and the other end of the folding component 623 is fixed to a slider 622 sliding in the second slide groove 621 through a rotating shaft component. The folding component 623 is composed of two rods and bearings. The two groups of the rods are rotated through the bearings to form an unfolding or folding state. The second slide groove 621 is screwed with a clamping screw 624 corresponding to the slider 622 from the outside. The clamping screw 624 tightens the slider 622 and is fixed in the second slide groove 621. By pushing the slider 622 to move in the second slider 622, the folding component 623 forms different angles through the bearing. The two folding components 623 of the auxiliary structure 6 form a triangle with the same angle. When the display screen moves on the transport structure 2, it follows the hypotenuse of the two groups of folding components 623 and passes between the end points of the two groups of folding components 623 to form a posture adjustment. By rotating the clamping screw 624, the slider 622 is fixed by increasing the friction force, and the orientation of the display screen entering the dispensing area is adjusted.
