The utility model relates to an adjustable airscrew which adopts an integral guide frame. The utility model includes a propeller hub, an oil cylinder, a piston, the guide frame, a vane sole, a slide block and a stern shaft; the guide frame is an integral guide frame formed by a hollow shaft which penetrates the center of a cube; the four corners of the cube are respectively provided with a winch pin; one end of the hollow shaft is connected with the piston and the other end is connected with the inner hole of the stern shaft; the vane sole is provided with a guide slot; the winch pins of the integral guide frame are arranged in the guide slot of the vane sole through the slide block. The adjustable airscrew has the advantages that: as the integral guide frame structure is adopted, the numbers of parts, the machining load and the chip test cost can be reduced; the reliability of the parts can be enhanced; as no winch pins are arranged on the vane sole, while the guide slot is arranged on the vane sole, the size of the blank of the vane sole is reduced, the cost is reduced and the rough machining load is reduced; as the integral guide frame is adopted, the whole adjustable airscrew is more conveniently arranged.
