Removable storage device module

The present invention generally relates to a removable storage device module; and more particularly to a removable hard disk module.

With the development of information technology, the application of computers has become quite popular. The places where they are used are no longer restricted to indoor spaces such as offices or homes, and are extended to vehicles such as vehicles and ships. On the other hand, most of the software and access data used by the computer are stored on the hard disk. Therefore, the hard disk is the most important data storage component of the computer. In the early days, when the hard disk failed or needs to be replaced, the computer case must be opened first, which is time consuming and laborious. In order to solve this problem, a removable hard disk module has been introduced in the market.

As shown in FIG. 1, a conventional removable hard disk module 80 includes a housing 10, a hard disk 30, and a locking device 70. Wherein, when the hard disk 30 is inserted into the casing 10, the card slot 31 on the hard disk 30 is aligned with the card hole 11 of the casing 10. The user can rotate the locking device 70 so that the tongue 71 simultaneously snaps into the card slot 31 and the card hole 11 to position the hard disk 30 in the housing 10. When the hard disk 30 is to be pulled away from the casing 10, the locking device 70 can be rotated to move the tongue 71 away from the card slot 31 and the card hole 11. Thereby, the hard disk 30 can be prevented from being arbitrarily detached from the casing 10. However, the above manner of positioning the hard disk 30 in the casing 10 not only needs to confirm that the card slot 31 is aligned with the card hole 11, but also the user must manually rotate the locking device 70. On the other hand, when the hard disk 30 is to be withdrawn from the casing 10, in addition to rotating the locking device 70, the hard disk 30 must be manually pulled away from the positioning position. The above design has room for improvement.
