Abstract: A storage device includes a housing with an opening at the front end for receiving at least one storage container pushed in which can store a storage element, one end of the storage container being provided with a positioning portion; at least one engaging member being jointed rotatably at the rear end of the housing, one end of each engaging member being provided with a connecting portion for engaging the positioning portion of the storage container pushed into the inner of the housing to fix the storage container, and another end of each engaging member provided with a pushing portion. When users turn the engaging member, the connecting portion releases the positioning portion and then the pushing portion pushes the rear end of the storage container subsequently to eject the storage container outwardly.
