Abstract

The present invention provides a manual fine-tuning rotating stage device, which mainly comprises a base, an adjustment unit configured on an outer side of the base, a rotating table, a first bearing configured between the base and the rotating table, a rotating column passing through the base and secured with the rotating table, a second bearing configured between the rotating column and the base, and a position limiting cover plate connected with the rotating column for limiting the position of the base between the limiting cover plate and the rotating table. When a manual rotating grip of the adjustment unit is moved toward a pushing position to push a pushing portion of the rotating table, an elastic column of the adjustment unit will be retracted to rotate the rotating table within a predetermined angle. When the manual rotating grip is moved toward a retracting position, the elastic column will push the pushing portion back by its elastic force, so as to reduce the overall thickness and achieve the effect of rotation fine-tuning.
