An electronic device includes a housing, an electronic module received in the housing, a locking member fixed to the electronic module and locked to the housing, and a releasing apparatus fixed to the housing. The releasing apparatus includes a mounting member fixed to the bracket, an operation member slidably mounted to the mounting member, a first connecting member hinged to the mounting member, and a second connecting member hinged to the first connecting member and the operation member. The operation member is pushed to drive the first connecting member and the second connecting member to rotate to raise a junction of the first and second connecting members, to resist against the locking member to be deformed and released from the housing.
