An electronic device includes a first body and a second body. The first body includes a connecting mechanism having a base, at least one locking member, a limiting member, and a driving member connected to the limiting member. The locking member includes at least one locking portion. The second body has a through hole. At least one of a plurality of inner sidewalls of the through hole has at least one locking hole. When the connecting mechanism is located in the through hole and the driving member is in a locked state, the locking portion is protruded from at least one opening of the base and extended into the locking hole. When the driving member is actuated to an unlocked state, the driving member drives the limiting member to move and the locking member moves relative to the base such that the locking portion is retracted into the base.
