ABSTRACT:
The electric scissor jack apparatus uses electrical power to elevate an automobile with a cigar lighter plug of an auto to power the high torque electric motor of the apparatus. The motor is in communication with the scissor jack via the gear reduction member so that maximum torque is applied to the scissor jack. Of significant importance is that the fail-safe coupling between the gear reduction drive and the scissor jack ensures against excessive or premature wear, failure, and danger to an operator. By avoiding any jack encasement, the apparatus provides for inexpensive multiple jack size utilization in that various sizes of scissor jacks are optionally fitted to the coupling housing of the gear reduction member.
