A server is a type of computer that runs faster, is more loaded, and is more expensive than a normal computer. The server provides computing or application services to other clients in the network (e.g., terminals such as PCs, smartphones, ATM, and even large devices such as train systems). The server has high-speed CPU operation capability, long-time reliable operation, strong I/O external data throughput capability and better expansibility.

At present, in a general server, a riser bracket is usually inserted into a guide slot of a die casting rear window at the tail part of a chassis at the tail part, and the middle part of the bracket is fixed by inserting a golden finger of a riser card locked on the bracket into a main board slot. In order to prevent the phenomenon that the riser bracket shakes or tilts under the condition of being impacted in the transportation process, a quarter quick-turn locking screw is fixed on the inner side of the front end of the riser bracket. The lock head of the quick locking screw can be rotationally locked into a limiting structure fixed on the corresponding position of the main board tray, so that the fixation of the riser bracket in the universal server case is realized. However, at present, one quarter of a quick locking screw has higher cost on one hand and larger operation occupation space on the other hand, so that a third slot position of a riser card can only be inserted with a half-length board card, if a 3/4-length card is inserted, the board card can cause interference with the quick locking screw structure, and a plurality of raid cards with outgoing lines at the tail can only be inserted under the condition that the board card is not interfered with the quick locking screw structure.
