A collapsible handle device for an inflator comprises an air cylinder having a shaft lever and a hollow grip, in which one end of the shaft lever is connected to a piston inside the air cylinder, and the other end is provided with a rotation body, which is pivotally jointed with the grip. A channel, wider than the diameter of the shaft lever, is formed in the lateral wall of the grip. The air cylinder could be inserted in the grip so as to reduce the volume of the inflator, or the air cylinder could be pulled out from the grip, then turned 180° to form a straight line with the shaft lever so that a user may hold the air cylinder with one hand and operate the shaft lever in axial direction to pump air out through an air vent at one end of the air cylinder.
