Abstract
A powered ratchet drive for a ratchet wrench includes a pair of elongate pawls for driving an output member of the wrench. Each pawl may have a lower portion pivotally attached to a rocker and an upper portion comprising teeth for engagement with teeth of the output member to turn the output member. The upper portion of the pawl extends outward at an angle with respect to the lower portion. The ratchet may include a compression spring secured inside a cavity of each pawl for biasing the pawl into engagement with the output member. The ratchet also includes a reversing switch mechanism for selectively configuring the ratchet in a forward-driving configuration and in a reverse-driving configuration. The switch mechanism includes a cam disposed between the pawls. The cam has a groove for receiving one of the pawls during operation depending on the configuration of the ratchet.
