Hard disk loading and unloading structure and server

The embodiment of the invention relates to the technical field of hardware assembly, and discloses a hard disk loading and unloading structure and a server. By setting a flip type hard disk mounting mode, the hard disk is inserted into the slot formed in the turnover piece, then the turnover piece rotationally connected with the base is rotationally retracted into the accommodating groove in the base, so that the hard disk can be obliquely mounted in the accommodating groove in the base at a certain angle, and finally, the turnover piece is moved on the base, so that the hard disk can be mounted in the accommodating groove in the base. The interface of the hard disk is connected with the hard disk connector in the containing groove in an inserted mode, installation of the hard disk is completed, the space occupied when the hard disk is inserted and pulled in the installation or disassembly process of the hard disk can be reduced, and the hard disk can be inserted and installed at an inclined angle instead of
