摘要

An air motor socket wrench has an air motor secured to a housing of a socket drive assembly having a socket drive member provided with a socket lock ball movable between a socket lock position and a socket unlock position. A hexagon body has inwardly inclined ramp sections adjacent an inside continuous cylindrical wall of a yoke drivably connected to the motor to oscillate the yoke. Rollers located between the ramp sections and cylindrical wall of the yoke transmits rotational movement of the yoke to the body and socket drive member. A muffler mounted on the air motor reduces the noise generated by the air motor.
