1. A circuit board, adapted for inserting an expansion card, wherein the expansion card comprises an electrical contact part, a non-electrical convex part, and a positioning part, and the circuit board comprising:
a board body;
a slot, disposed on the board body, comprising:
a socket, adapted for the electrical contact part to be inserted;
a connecting end, adjacent to the socket; and
an outer surface, adjacent to the socket and away from the connecting end;
a release structure, movably disposed at the connecting end and comprising a limiting part; and
a transmission mechanism, disposed in the socket, adjacent to the connecting end, or adjacent to the outer surface, comprising:
a driving member, adapted for contacting the electrical contact part, the non-electrical convex part, or the positioning part; and
a linking member, disposed between the driving member and the release structure, wherein the driving member is linked to the linking member, and the linking member is linked to the release structure, wherein
when the electrical contact part is inserted into the socket, the electrical contact part, the non-electrical convex part, or the positioning part presses the driving member, the driving member drives the linking member to move, thereby driving the release structure to move, so that the limiting part is limiting to the positioning part,
wherein the release structure is movably disposed at the connecting end, the linking member and the release structure are integrated, when the electrical contact part is inserted into the socket, the expansion card presses the driving member to drive the release structure to move toward the socket, so that the limiting part limits the positioning part.
