The fine-turning bracket is provided a photosensitive element and an illuminating lamp which correspond with each other, and is used for performing fine-turning on the positions of the photosensitive element and the illuminating lamp. A bearing is arranged on the bearing seat. The bearing is sleeved at the bottom end of a rotating mandrel. The rotating mandrel passes through a central hole on a code disc so that the code disc rotates together with the rotating mandrel. The top end of the rotating mandrel is provided with a shaft coupling which is connected with a servo motor. A code channel on the code disc is arranged between the photosensitive element and the illuminating lamp which correspond with each other. The encoder verifying mechanism provided by the utility model can effectively verify a majority of encoders and has relatively high verifying precision.
