  • Publication number: 20050178247
    Abstract: A ratcheting tool includes a body and a gear disposed in the body. The gear defines a plurality of teeth on a circumference of the gear. A pawl is disposed in the body so that the pawl is movable with respect to the gear between a first position, in which the body transmits torque through the pawl in a first rotational direction, and a second position, in which the body transmits torque through the pawl in an opposite rotational direction. The pawl defines a plurality of teeth facing the gear and engages a reversing lever that urges the pawl between the first and second positions. The reversing lever comprises a handle portion and bottom portion that receives a clip spring. The detent urges the pawl between the first and second position by engaging the walls of a recess in the back of the pawl.
