Abstract
A power device for a pneumatic packing tool includes a gas delivery unit and a pneumatic unit. The gas delivery unit has an accommodation room, an air inlet, and air outlets. The accommodation room includes a turning block having an input passage. An expansion space is defined between the turning block and the accommodation room. The expansion space communicates with the air outlets. An outer circumferential side of the gas delivery unit is provided with a knob. A push rod is inserted in the knob and the turning block. The pneumatic unit has two through holes. Through the knob, the turning block is turned for the input passage to communicate with one of the through holes to set the direction of winding a belt quickly, and the gas flows from the other through hole to the expansion space to be expanded and exhausted to eliminate the noise.
