The connecting portion is disposed on a first direction surface of the casing for coupling with an electronic device connector, the pressing button is disposed on a third direction surface of the casing, and the hook module is disposed between the connecting portion and the pressing button. In addition, when the pressing button is pressed in the third direction, a hook end of the hook module is moved along a second direction on a protective shell of the connecting portion for separating from the electronic device connector.
