Flow way structure of pneumatic tool, including: a main body; a connector rotatably disposed on the main body; an air inlet, a water inlet and at least one air outlet concentrically arranged on the connector, inner end of each air outlet communicating with an air chamber of the main body; an air inlet switch and a water inlet switch mounted in the main body for controlling the flow of the fluid; an air way for conducting the air into the main body and communicating with a pneumatic cylinder disposed in the main body; and a water way for conducting the water into the main body. Two ends of the air way and water way are concentrically respectively connected with the air inlet and water inlet. When the connector rotates on the main body, the air inlet and the water inlet respectively still keep communicating with the air way and water way. In use, the air and water are respectively conducted from the air way and water way into the main body. The air drives the cylinder and then is exhausted through the air chamber from the air outlet. The water is drained out from water outlet tubes connected with the main body.
