Abstract: This invention relates to a lockup structure of mobile hard drive, and comprises a base plate for receiving a hard drive, a lock member having a block sheet, a base frame having a through hole for mounting the lock member, and a spiral arm. At a free end of the spiral arm comprises a protruding block for locating into the base plate and a notch for positioning the block sheet of the lock member, and at a fixing end comprises a position block mounted into a shell.

Abstract: A case for removable hard drive includes a main body, a back cover, and more than one hard disk holders. The hard disk holder is configured for connecting and carrying a hard disk. The main body is a three-dimensional frame made of a metal material by way of stamping, and provided between two lateral sides with a plurality of slide rails, into which the bard disk holders are slid to locate thereat. The main body and the back cover are detachably connected together through a fastening structure. While the main body is produced to have a uniform specification, the back cover that has relatively small volume and simple structure may be fabricated according to different specifications of hard disks to be held in the main body, so that the whole case for removable hard drive may be produced at reduced cost and used in a more flexible manner.
