The invention belongs to the technical field of camera shooting. The invention discloses an Alvarez zoom lens driving mechanism and a driving device. The Alvarez zoom lens driving mechanism comprises a shell; the rotating disc is connected into the shell and configured to rotate relative to the shell, a pair of arc-shaped grooves are formed in the rotating disc, and the distances, close to the center of the rotating disc, of the two ends of each arc-shaped groove are different; the first lens unit and the second lens unit are respectively in limiting sliding fit with the shell; wherein the extending end of the first lens unit and the extending end of the second lens unit respectively extend into the pair of arc-shaped grooves, so that the rotating disc drives the first lens unit and the second lens unit to move in opposite directions. According to the invention, the rotating disc can be used for driving the extending end to move, the first lens unit and the second lens unit are close to each other or far away
