[0002] The server hard disk bracket is a device for fixing the server hard disk, and is usually a bracket provided with a mounting groove. The hard disk is placed in the mounting groove on the bracket, and the hard disk is locked and fixed on the bracket through bolts or other bracket components, so that the hard disk is stably fixed on the bracket during the use of the server, thereby reducing the possibility of the hard disk shaking and other unexpected situations affecting the use of the server.

[0003] During the assembly of the server hard disk bracket, the bracket is commonly composed of a bottom plate and two side plates, and the side plates are assembled on the bottom plate by means of bolts or plug-in clamping.
