A turbo pneumatic cylinder of a pneumatic tool, including a front turbine, a one-way rotatable inverse turbine and a rear turbine. The front and rear turbines are mounted on the rotary shaft of the pneumatic cylinder. The inverse turbine is one-way rotatably fitted on the rotary shaft between the front and rear turbines. Multiple blades are arranged on the circumferences of the front and rear turbine and the inverse turbines. The blades of the inverse turbine are directed in a direction reverse to the direction of the blades of the front and rear turbines. The front and rear turbines and the rotary shaft rotate in the same direction, while the inverse turbine rotates in a direction reverse to the direction of the front and rear turbines. As a result, the efficiency of the pneumatic cylinder is enhanced and the twisting of the pneumatic cylinder is avoided when it is in operation.
