Improved balance correcting machine drive structure

The utility model provides a modified drive structure for a balancing and straightening machine on a pedestal, which at least comprises a dynamic element, a sensing element and a bearing bracket. Wherein, the dynamic element is provided with a driving revolving element. A sensing revolving element is arranged for the sensing element. Besides, the bearing bracket is pivoted with an adapting element and an adapting revolving element to drive the adapting element. The driving revolving element links and drives the adapting revolving element. The adapting revolving element is connected with the sensing revolving element. Therefore, the sensing revolving element is capable of directly receiving intact revolving information from the adapting element and adapting revolving element, thus improving value sensing accuracy of the sensing element.
