Abstract
A driving mechanism with linear clamp for driving a rotatable ring of a lens on a camera to rotate including a base, a driving unit, a slave unit and a clamping unit is provided, wherein the rotatable ring can be a focus ring or a zoom ring. The camera is hold on the base, while the driving unit and the slave unit are glidingly disposed on the base and located at opposite sides of the lens. The driving unit includes at least a driven wheel, and the slave unit includes at least an idler wheel. The clamping unit is disposed on the base for synchronously moving the driving unit and the slave unit toward the lens to let the driven wheel and the idler wheel lean against the rotatable ring in different directions, so the idler wheel will be rotated when the driven wheel drives the rotatable ring to rotate.
