Background technique

By the way, with the advent of the diversified information age, all kinds of electronic products are flooding around the living environment. With the continuous innovation and progress of science and technology, electronic products are also moving towards multi-function, purpose and additional hardware equipment. Many electronic products use computers to control their actions or perform functions, so computers play an extremely important role.

As the processing performance of computers and servers is getting higher and higher, more and more data needs to be stored in the hard disk, and it will not be enough to set only one or two hard disks in the casing of the computer host, and it must be continuously expanded and added. Electronic devices such as hard disks, CD-ROM drives, and burners, so as to achieve the multi-functional effect of the computer host.

Generally, computers use screws to fix hard disks or other devices in the chassis, and the screws must be aligned and screwed into the fixing screw holes, which takes a long time and greatly increases the time for downtime maintenance. If it is a server chassis, the racks are very thin, and the height between the racks is not high. Regardless of whether it is a computer or a server, the chassis is full of various devices such as adapter cards, hard disks, and power cords. It is very inconvenient for the screwdriver to perform the locking action.

Therefore, how to solve the problems and problems of complicated and time-consuming operation of quick-release buckles, and cause the lack and inconvenience of effectively reducing the maintenance time of the computer room, is the direction that relevant manufacturers engaged in this industry are eager to study and improve.

The known technology also has a screw-free hard disk quick release structure, but it is bulky and occupies the space inside the chassis of the computer host. As the size and specifications of the chassis of the mainframe computer become increasingly stringent, and the size becomes smaller and smaller, the known quick-release hard disk structure is gradually unable to be applied to the mainframe computer in the future.

Therefore, it is necessary to provide an electronic device with an extraction structure to solve the above problems.
