The hard disk drive tray has a front frame. An elastic cantilever plate is extended from each of two ends of the front frames. The couple of elastic cantilever plates are arranged parallel with each other for clamping the hard disk drive between the couple of elastic cantilever plates. A lateral surface of each elastic cantilever plate is covered by a side case and an expansion fastening bolt for fastening the hard disk drive is arranged protruding from the other lateral surface of each elastic cantilever plate. The hard disk drive is clamped by, the elastic cantilever plates, a simplified structure of the hard disk drive tray. The elastic cantilever plate is covered by the side case and thereby reinforced. ## Claims ### Claim 1 A hard disk drive tray for accommodating a hard disk drive, the hard disk drive tray comprising a front frame, an elastic cantilever plate being extended from each of two ends of the front frame, the elastic cantilever plates being coupled and arranged parallel with each other for clamping the hard disk drive between the elastic cantilever plates, a lateral surface of each elastic cantilever plate being covered by a side case and an expansion fastening bolt for fastening the hard disk drive being protruded from the other lateral surface of each elastic cantilever plate. ### Claim 2 (depends on 1) The hard disk drive tray according to claim 1, wherein at least a hook is extended from an edge of each elastic cantilever plate, and the respective hooks hook the respective corresponding side cases. ### Claim 3 (depends on 1) The hard disk drive tray according to claim 1, wherein an internal flange is formed by an inward reversed edge of the side case to be extended, and the internal flange is arranged to surround the side case and cover an edge of the elastic cantilever plate. ### Claim 4 (depends on 3) The hard disk drive tray according to claim 3, wherein an opening is defined on the internal flange at an end of the side case, a latch is arranged in the opening, the elastic cantilever plate is inserted in the side case through the opening, and the latch latches the edge of the elastic cantilever plate. ### Claim 5 (depends on 1) The hard disk drive tray according to claim 1, wherein the respective elastic cantilever plates are one piece extended from the front frame. ### Claim 6 (depends on 1) The hard disk drive tray according to claim 1, wherein a positioning pin for fastening the hard disk drive protrudes from the elastic cantilever plate, the positioning pin and the expansion fastening bolt are arranged on the same surface of the elastic cantilever plate, the positioning pin is arranged between the front frame and the expansion fastening bolt, and the positioning pin is shorter than the expansion fastening bolt. ### Claim 7 (depends on 1) The hard disk drive tray according to claim 1, wherein a slider structure arranged along a longitudinal direction of the corresponding elastic cantilever plate is formed on an external surface of each side case. ### Claim 8 (depends on 7) The hard disk drive tray according to claim 7, wherein a positioning arm is formed on a surface of each elastic cantilever plate, and the respective positioning arms are arranged to penetrate the respective corresponding side case and thereby being protruded from a surface of the slider structure. ### Claim 9 (depends on 7) The hard disk drive tray according to claim 7, wherein a communicating channel is defined on the side case and along the longitudinal direction of the corresponding elastic cantilever plate, and a light guiding bar is inserted in the communicating channel. ### Claim 10 (depends on 9) The hard disk drive tray according to claim 9, wherein a panel is arranged on the front frame and an end of the light guiding bar is exposed on the panel. ### Claim 11 (depends on 9) The hard disk drive tray according to claim 9, wherein a handle is arranged on the front frame.
