Abstract: A storage device includes a mounting component, a storage component, and at least one elastic piece. The mounting component and the storage component are mounted on wall surfaces at intervals in a gravity direction. The at least one elastic piece is connected between the mounting component and the storage component. The at least one elastic piece, the mounting component, and the storage component are enclosed to define a storage space. Under driving of an external force, the at least one elastic pieces is deformed to define an entrance of the storage space. The storage device prevents articles stored therein from falling, thus reducing a potential safety hazard.
