Abstract
The pneumatic tool having pendulum-like direction switching mechanism of the present invention includes a pneumatic motor and a control valve. The control valve is utilized for receiving pressurized air and for alternatively leading air into the pneumatic motor to drive and control the pneumatic motor. The present invention further includes a switching device and a coupling mechanism. By connection of the coupling mechanism, the switching device is able to control motion of the valve. In addition, the switching device slides along an arc-shaped route. Thus, the switching device approaches the pneumatic tool without protruding excessively. Therefore, unexpected collision is lessened and lifetime is prolonged.
