Description

technical field [0001] The invention relates to a fixing device, in particular to an expansion card fixing device. Background technique [0002] With the rapid development of the computer information industry and the expansion of its application scope, people's requirements for computer functions are constantly increasing. Usually, multiple functional hardware needs to be added inside the computer, and the expansion card is the most common device for improving computer functions. A general computer system is usually equipped with several expansion cards with different functions, such as a graphics acceleration display card, a video card, a network card, and a sound card. The back panel of the computer casing is provided with several expansion card slots. In the prior art, one side of the expansion card is usually locked on a metal fixing piece, and then the fixing pieces are locked one by one to one side of the expansion card slot on the rear plate by screws, thereby fixing...
