Abstract

The invention relates to a precision mechanism light driving technology, which comprises a composite outrigger which is formed by a set of piezoelectric ceramic sheet with two electrodes and a base chip, a hinge, a reflecting lens and frame, and a supporting frame. The lens frame is connected with the base chip by the hinge; the base chip is fixed by the supporting frame. When the positive end of the power is paralleled with the two sets of the electrode area, the negative end of the power connects with the base chip, so that the composite outrigger generates a bend deformation; when the positive end and the negative end of the power are separately connected with the two sets of the electrode area, the composite outrigger generates a torsion deformation. The composite outrigger can also be formed by four cruciform symmetrical distributing outriggers with the reflecting lens in the center of the cruciform symmetric or by two vertical outriggers with the reflecting lens on the vertical point; the lens frame is connected with the supporting frame.
