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.

Abstract: An aluminum alloy housing structure and method making the same. By placing said aluminum alloy housing to be processed in a processing device, processing the skin of said aluminum alloy housing in a mechanical procession manner without involving any chemical solution to form on the skin of said aluminum alloy housing a recess region having a plurality of fine holes, and binding directly a highly flowing plastic material in said recess region by injection-molding, in combination with a mold, said plastic material into said recess region, thereby an environment-friend aluminum alloy/plastic composite with good binding ability can be form on said aluminum alloy housing.
