Provided are an optical anti-shaking mechanism, a lens driving device, and an imaging equipment. The optical anti-shaking mechanism includes: a movable body configured to install a sensor, a fixed body configured to support the movable body, a resilient anti-shaking frame resiliently connected to the fixed body and the movable body and configured to make the movable body overhang the fixed body, and a driving assembly including: an X-axis driving assembly configured to drive the movable body to move along an X-axis in a horizontal plane perpendicular to an optical axis, and a Y-axis driving assembly configured to drive the movable body to move along a Y-axis in the horizontal plane perpendicular to the optical axis. The translation movement of the image sensor perpendicular to the optical axis is realized, and the object of optical anti-shake of the translation movement of the image sensor is achieved.
