Description

computer case

technical field

The present invention relates to a computer case, and in particular to a computer case for fixing or removing a detachable device without tools.

Background technique

With the rapid development of digital technology, the application of digital products is becoming more and more popular, and the progress of computer-related peripheral industries is even more rapid. In order to enable the computer to handle the different needs of each person, most manufacturers design a storage space in the computer casing to accommodate various expansion-use detachable devices (such as CD-ROM drives, hard disk drives, floppy disk drives, burners, etc.). device, etc.). Wherein, after the detachable device is put into the accommodating space, the computer case will most likely be provided with a fixing structure for fixing the detachable device in the accommodating space.

In the prior art, screws are mostly used to lock the detachable device in the computer case. Therefore, tools such as screwdrivers and screwdrivers need to be used every time the detachable device is fixed or detached. In other words, the detachable device cannot be fixed or detached without tools at the user's hand.

As can be seen from the above, how to design a computer case that can fix or disassemble the detachable device without tools has become an important issue.
