Various expansion cards (such as sound cards, network cards, etc.) conforming to the pci (peripheral Component interconnect) standard are widely used in various electronic devices. The expansion card is connected with the electronic equipment and installed in the electronic equipment by inserting the pins into the PCI slot of the electronic equipment. However, the installation method has poor stability, and the expansion card is easy to loose. In order to prevent the expansion card from loosening, a metal blocking piece is usually fixed on the side edge of the expansion card, and after the expansion card is inserted into a corresponding expansion card slot on a mainboard, the metal blocking piece of the expansion card is fixed on a computer shell, so that the expansion card can not fall off and still keeps good electrical connection with the computer mainboard when the computer is moved or accidentally impacted.
One of the conventional methods for fixing the expansion card retaining piece is to press a pressing plate thereon, and then fix the pressing plate to the computer housing by screws, thereby fixing the expansion card retaining piece. The method can fix the blocking pieces of a plurality of expansion cards at one time, but screws need to be assembled and disassembled, so that the operation is inconvenient; the other method is to make the expansion card pressing device into an automatic turnover structure without locking screws. Although the two types of card pressing structures can meet the requirements in terms of strength, the cost is high, the advantages in terms of price are not too much, and the current trend of developing products by taking cost as a guide cannot be met.
