Abstract: The invention relates to motor driven scissors jacks for automobiles and is driven by the electric power source from the cigarette lighting socket of any automobile. Its DC motor is driven through a deceleration gear box for rotating a screw rod clockwise or counter-clockwise in order to provide for the raising of the frames of scissors jacks with automatic raising of vehicles and for the higher raising and lower collapsing functions and a more powerful raising capability. It is also provided with one ultimate switch for peak and low bottom points in order to limit its raising and collapsing operation to fixed points and an automatic stop for safe raising operations and for preventing damage to the motor.
