A zoom lens control mechanism for changing a focal distance in an optical axis of a first lens set includes a zoom lens base, a lens support, and a switch device. The zoom lens base has an image pickup opening disposed in the optical axis of the first lens set. The lens support is disposed on the zoom lens base, with one end rotatably disposed on the zoom lens base, and the other end with a second lens set. Herein, when the lens support rotates, the second lens set shifts between an active position and a leaving position along the surface of the zoom lens base. When the second lens set is at the active position, the focal distance may be changed according to a curvature of the second lens set.
