Hard disk tray capable of rotating vertically

The invention relates to the field of hard disk supports, and solves the problem that a hard disk cannot be replaced when no operation space exists above a server in the prior art. The hard disk traycapable of rotating vertically includes a hard disk mounting part, first mounting frames are fixedly connected to the two sides of the hard disk mounting part, second mounting frames are rotationallyconnected to the first mounting frames, limiting operation pieces are arranged on the first mounting frames, limiting pins are fixedly connected to the limiting operation pieces, through holes allowing the limiting pins to penetrate through are formed in the first mounting frames, and limiting holes matched with the limiting pins are formed in the second mounting frames. After the hard disk frameis pulled out of the case, the limiting operation piece is pressed to enable the limiting pin to be separated from the limiting hole, the hard disk installation part rotates relative to the second installation frame, when no op
