PURPOSE: A locking device of a drawer safe with a multistage opening and closing structure is provided to improve safety by unlocking the safe by an electrical signal. CONSTITUTION: A withdrawal prevention protrusion is fixed in a predetermined position of a safe housing and prevents the withdrawal of the safe box according to the lock operation of a lock device. A lock button(605) is equipped in one side of the body and performs the lock function by the pressurization of the withdrawal prevention protrusion. A lock arm(603) is rotated for converting the locking state in response to the operation of the lock button and performs the unlocking operation when the rotation force is applied from the outside. A cam(609) operates a lock arm by synchronizing with the rotation force. An actuator(515) is integrated with the lock device and controls the rotation of the cam by an electrical signal.
