An electronic device with quick releasing function for an interface card includes a base, a connector and a quick releasing mechanism. The base is adapted to hold the interface card. The connector is disposed on the base to electrically connect with the interface card. The quick releasing mechanism is disposed on the base and includes a first constraining component and a second constraining component. The first constraining component is movably disposed on the base and can be shifted between a releasing position and a constraining position. The first constraining component moves to the constraining position to contact against a side of the interface card opposite to the connector. The second constraining component is disposed on the base and located on another side of the first constraining component to contact against the interface card corresponding to the connector.
