Abstract
An impact tool includes a housing, a motor having an output shaft defining a first axis, a drive shaft rotatably supported by the housing about a second axis oriented substantially normal to the first axis, and an impact mechanism coupled between the motor and the drive shaft and operable to impart a striking rotational force to the drive shaft. The impact mechanism includes an anvil rotatably supported by the housing and coupled to the drive shaft and a hammer coupled to the motor to receive torque from the motor and impart the striking rotational force to the anvil. A ratcheting mechanism prevents rotation of the drive shaft in a selected direction relative to the housing and includes first and second pawls movably coupled to one of the drive shaft and the housing, and ratchet teeth defined on the other of the drive shaft and the housing.
