Abstract
A hand-held pneumatic tool includes a tubular body, an inlet device and a switch device respectively mounted in a first end of the tubular body. A pneumatic motor is mounted in a middle portion of the tubular body and has a shaft longitudinally extending from the pneumatic motor relative to the tubular body. A coupling is mounted on a free end of the shaft and has a first bevel gear formed on a distal periphery thereof. An output device is mounted in a second end of the tubular body and driven by the pneumatic motor. The output device includes a first output axle having a second bevel gear formed to engage to the first bevel gear of the coupling. A second output axle is longitudinally and securely mounted to the coupling so that the coupling directly drives the second output axle.
