A safety outlet installed in a wall is provided to shield a plug and a plug connecting part and prevent impurities from being flowed in terminal insertion holes by rotating a lever downward and mounting a plug connecting part in a receiving groove. A driving unit(400) comprises a motor(410), first and second circuit parts(420,430), a lever(440), and a plunger. A polarity of the motor is changed as a direct current motor to change a rotary direction of an output shaft(411). The first circuit part includes a first power source(421), a first switch(422), and a solenoid(423), and is serially connected with the motor. The first switch is serially connected with the first power source. The second circuit part includes a second power source(431) and a second switch(432). A polarity of the second power source is changed and opposed to the first power source when connected to the motor. The lever has a conductor so that the first or second switch is closed to control the electric flow between the first and second circuit parts. When the lever is moved upward, a rotary shaft is rotated to one direction to expose a plug connecting part to the outside. When the lever is moved downward, the motor is rotated reversely to mount the exposed plug connecting part in a received groove. |
