摘要： A pneumatic rotary tool includes a housing, a directional changeover mechanism, and a speed regulating mechanism. The housing includes a top body and a handle. The top body is fitted with a pneumatic motor. The handle defines a forward air channel, a reverse air channel, and an air supply passage. The air supply passage is controlled by a valve being operated by a trigger so that the air supply passage communicates with the forward and reverse air channels. The direction changeover mechanism is mounted in the top body along a transverse line and passes through the forward and reverse air channels for changing the rotational direction of the pneumatic motor. The speed regulating mechanism is mounted in the handle for adjusting the flow of compressed air entering the forward air channel. The tool can be operated conveniently to change the rotational direction and the output torque of the pneumatic motor.
