1. A circuit board device, adapted for inserting an expansion card, wherein the expansion card comprises an electrical end and a locking part, the circuit board device comprising:
a circuit board body;
a slot, disposed on the circuit board body; and
a linkage structure, rotatably disposed on the circuit board body and located beside the slot, the linkage structure comprising:
a connecting rod, having a first end and a second end opposite to each other and an axis;
a pressing part, connected to the first end and deviating from the axis; and
a fixing part, located at the second end and having:
a hook, close to the slot and deviating from the axis, and having a first slope facing away from the circuit board body;
an elastic arm, close to the slot and the hook; and
a fixing member, extending from the elastic arm towards the slot and comprising a second slope facing away from the circuit board body and a third slope facing the hook,
wherein when the electrical end is inserted in the slot, the locking part pushes against the first slope, so that the linkage structure rotates around the axis, and the hook gives way, and the locking part pushes against the second slope, and the elastic arm deforms, so that the fixing member gives way, and the expansion card is fixed between the fixing member and the hook.
