[0002] Function cards such as M.2 disks, mSATA disks, mini PCI e cards, etc. are a common expansion device. When in use, they need to be inserted into the corresponding interface slots on the motherboard, and the other end must be fixed with screws to ensure that the function card is firmly connected and runs on the motherboard; these function cards are usually inserted into the onboard connector interface of the interface slot and ensure that the function card matches the slot. Then, fix the other end with screws to make the function card tightly combined with the motherboard. The screws are usually located in the external port or other designated locations of the function card, and the function card is connected to the motherboard through the screw holes. The purpose of fixing the screws is to prevent the function card from loosening or disconnecting during use. In actual operation, it is often easy to lose the screws that fix the other end, resulting in the inability to find a suitable screw to fix it after replacing the function card.
