When the positioning cover is located at the first position, the linkage portion is adjacent to the second opening, and when the positioning cover is located at the second position, the linkage portion is located above the support frame and is suitable for abutting against the mounting plate.

Based on the above, the fixing device in this case is suitable for the computer chassis and is used to fix the graphics card. During the installation process, align the graphics card with the carrier on the base, and then push the positioning cover to rotate relative to the base with bare hands and use the linkage part to abut against it. on the mounting plate of the graphics card to position the graphics card. During the disassembly process, push the positioning cover to rotate relative to the base to move the linking part away from the display card to release the positioning, and then remove the display card with bare hands. Therefore, the fixture in this case does not require external tools to complete the steps of installing and removing the graphics card, so it can improve the assembly efficiency of the graphics card and similar expansion cards, and also simplify the maintenance process.

In short, the fixing device of this case has the following features: 1. It adopts a special buckle structure to simplify the assembly process of display cards and similar expansion cards, 2. It replaces the existing screw locking with a positioning cover, so no external tools are required.
