Method and apparatus for adapting a socket wrench
View Patent ↗An adapter for a socket wrench includes a shaft with two socket drivers disposed along the shaft. Each of the socket drivers can, independent from one another, rotate around the shaft and slide along the shaft in either direction. There are two stops at each end of the shaft to prevent the socket drivers from falling off the shaft. The socket drivers can be attached to a variety of different socket accessories and sockets so that torque applied to one of the socket drivers can be multiplied and exerted at the end of the other socket driver. One particular embodiment includes a shaft and pedal that aids a person in correctly and easily tightening or loosening lug nuts.
