[0002] In the era of big data, a large number of IT equipment will be concentrated in the chassis of the data center. These data centers contain various types of servers, storage, switches, and a large number of cabinets and other infrastructure. Each IT device is composed of various hardware boards, such as computing modules, storage modules, chassis, fan modules, etc. Due to the long-term operation of the server, the various components in the server often need regular maintenance. Among them, the hard disk has a high frequency of maintenance or replacement due to frequent data interaction. In order to facilitate the maintenance of the hard disk by maintenance personnel, a hard disk box with an auxiliary extraction component is usually set on the outside of the hard disk to form a hard disk module, and then the entire hard disk module is inserted into the chassis. However, this structure takes up more space and is not conducive to the layout of the hard disk. Utility Model Content

[0003] Based on this, it is necessary to provide an auxiliary removal structure and a hard disk assembly to address the problem of hard disk maintenance.

[0005] The extraction aid comprises a handle and a shell which are rotatably connected, wherein the handle can rotate relative to the shell so that an end of the handle is separated from the shell;

[0006] The adapter bracket is used to be arranged between the extraction aid and the hard disk. The adapter bracket includes a bracket body and a support ear. The support ear is connected to the shell. The bracket body is used to be installed at one end of the hard disk away from its plug-in part.

[0007] The above-mentioned extraction-aiding structure connects the outer shell of the extraction-aiding device to the ear of the adapter bracket, and installs the bracket body of the adapter bracket at the end of the hard disk away from its plug-in portion, that is, the extraction-aiding device is connected to the hard disk through the adapter bracket, and the extraction-aiding structures are all located at the end of the hard disk away from its plug-in portion. When the hard disk needs to be plugged in or out, the handle can be rotated relative to the outer shell so that the end of the handle is separated from the outer shell, thereby facilitating hand holding. The present application can connect the extraction-aiding device and the hard disk by installing the adapter bracket at the end of the hard disk away from its plug-in portion. The extraction-aiding structure of the present application does not need to be mounted on the hard disk, but only needs to be installed at the end of the hard disk away from its plug-in portion, thereby reducing the size of the combined extraction-aiding structure and the hard disk and improving the space utilization rate of the hard disk.

[0008] In one embodiment, the bracket body and the ear are both plate-shaped, and the size of the bracket body is less than or equal to the end face size of the hard disk. The ear is inclined with respect to the bracket body, and the ear extends in a direction away from the bracket body.

The reset of the key is achieved by providing the first torsion spring.

[0020] In one embodiment, the extraction aid further includes a second connecting shaft, the housing has a chamber, and the second connecting shaft is connected to the wall of the chamber;

[0021] The handle has a first end and a second end distributed along its length direction, the second end is sleeved on the second connecting shaft, and in the first state, the first end is engaged with the button, and in the second state, the first end is separated from the button.

[0022] By arranging a second connecting shaft in the cavity, a part of the second end of the handle extends into the cavity and is sleeved on the second connecting shaft. When the button is pressed, the first end of the handle is separated from the button and the second end rotates around the second connecting shaft.

[0023] In one embodiment, the extraction aid further includes a second torsion spring, which is sleeved on the second connecting shaft, and one end of the second torsion spring is connected to the cavity wall of the cavity, and the other end of the second torsion spring is abutted against the first end.
