Abstract
A pneumatic tool includes a housing formed with an internal blowing flow way and an intake flow way. A blowing nozzle is disposed on a certain section of the housing and connected with a front end of the blowing flow way. A pneumatic cylinder is installed in a cylinder room of the housing. A switch is arranged between the intake flow way and the cylinder room and switchable between an intake position and a blowing position. High-pressure air flows from the intake flow way to the switch. An air conduit is formed on a front end of the switch. A shift button is mounted on the housing and connected with the switch. In use, when the switch is switched to the intake position, the air conduit of the switch communicates with the intake of the cylinder for driving the cylinder. When the switch is switched to the blowing position, the air conduit communicates with the rear end of the blowing flow way, whereby the high-pressure air blows out from the blowing nozzle to blow away dusts and chips. Accordingly, the pneumatic tool is able to blow dust and chips away.
