[0007] The side cover lock is used to lock and unlock the side cover from sliding backward when the side cover blocks the side opening;

[0008] The hard disk rack is used for installing and fixing the hard disk, and a hard disk rack plug-in plate is formed on one side of the hard disk rack. A hard disk rack socket is formed on the case wall around the side opening of the chassis body, and the hard disk rack plug-in plate is used to be inserted into the hard disk rack socket. When the hard disk rack plug-in plate is inserted into the hard disk rack socket, the other side of the hard disk rack can be swung into or out of the chassis body from the side opening;

[0009] The hard disk rack lock is arranged at a position on the hard disk rack that can swing with the hard disk rack, and is used to lock or unlock one side of the hard disk rack that swings on the chassis body when the hard disk rack is swung into the chassis body.

[0010] Furthermore, the rear edge of the side cover forms a flange, and when the side cover slides forward into the side edge of the chassis body, the flange abuts against the rear end plate of the chassis body;
