As far as general computer mainframes are concerned, various adapter cards are vertically inserted into the adapter card slots on the motherboard in a manner perpendicular to the motherboard of the computer. The set height of the card without being able to shrink or thin the case properly. In addition, there is another way of using slot conversion. An adapter circuit board is installed vertically on the motherboard, and an expansion slot is provided on one side of the adapter circuit board, and then the adapter card is inserted into the adapter circuit. In the expansion slot of the board, the adapter card can be installed in parallel with the main board, and the adapter card can also form an electrical connection with the main board through the transfer circuit board, so that the computer case can be moderately thinned, and the In a state of wasting space, more adapter cards can be plugged in. However, the above-mentioned method still has its disadvantages. If multiple adapter cards are plugged into the adapter circuit board, because each adapter card is stacked on the circuit board, and because the internal space of the casing is small, when the user wants to When plugging and unplugging an adapter card close to the motherboard, in order to avoid accidentally damaging the surrounding electronic components during the extraction process, it is often necessary to remove the other adapter cards before pulling out the innermost adapter card, which is quite Time consuming and inconvenient.

In view of the above problems, there is currently an expansion device, as disclosed in US Patent No. US6373691, which mainly fixes the adapter circuit board on an expansion device, and the adapter card can be plugged into the adapter circuit board to be fixed on the expansion device , and the adapter circuit board has metal pins that can be plugged into the adapter card slot of the motherboard, so that the adapter card can be electrically connected to the motherboard through the adapter circuit board, and can also be fixed in the case through the expansion device.
