An electronic device includes a first body, a second body, a first pivot structure, a second pivot structure, and a locking structure not in contact with the second pivot structure. The second pivot structure is pivoted to the first body along a first axis through the first pivot structure. The second body is pivoted to the first pivot structure along a second axis through the second pivot structure. When the second body is unfolded to an open position along the first axis, the first pivot structure drives the locking structure to go to an unlocked state, and the second body is adapted to rotate along the second axis. When the second body is folded or unfolded to other positions along the first axis, the first pivot structure drives the locking structure to go to a locked state, and the locking structure stops the second body rotating along the second axis.
