The invention relates to an integrated optical device focus adjusting system that includes ultrasonic motor that at least has an optical lens identity and an imaging component. The ultrasonic motor contains rotor and stator that is connected by screw and directly driven together. The optical lens is set in the rotor or stator. The imaging component is set in the stator or rotor. Screw is set in the stator center hole. And outside screw is set at the rotor outside surface. The screw surface has taken antifriction process and coating antifriction material. The motor includes the second rotor, and the optical lens is set in the second rotor. Outside screw is set around the second rotor that would match with stator. The invention is simple structure, high efficient and has good practicability.
