Abstract
A pneumatic tool with changeable exhaust direction includes a tool main body and a direction change assembly. The tool main body includes a housing portion having a first exhaust channel. The direction change assembly includes an air guidance member and an adjustment member. The air guidance member is mounted onto the housing portion, and a second exhaust channel is formed with the air guidance member. The adjustment member is installed with a sealing ring. The adjustment member generates an axial movement relative to the air guidance member and along a first axis to move away from the air guidance member in order to open the second exhaust channel or to allow the sealing member to abut against the air guidance member in order to close the second exhaust channel. Accordingly, the exhaust direction is adjustable during the use of the pneumatic tool in order to facilitate different processing operations.
