Zusammenfassung:	The embodiment of the utility model discloses an opening and closing device, and relates to the technical field of opening and closing structures. The opening and closing device comprises a shell provided with an accommodating space. And the shell is provided with an opening part for communicating the accommodating space with the outside. The supporting piece is contained in the containing space and can be driven by the driving mechanism to move. Furthermore, the opening and closing device further comprises an adsorption structure, the adsorption structure is rotationally connected to the connecting end, exposed out of the shell from the opening portion, of the supporting piece, and therefore the supporting piece can be connected with the opening and closing structure through the adsorption structure, and opening and closing of the opening and closing structure are achieved through movement of the supporting piece. Therefore, damage to the opening and closing structure when the supporting piece is connected w
