Abstract
A focus lens regulation mechanism is provided. The focus lens regulation mechanism includes a base, a screw rod, a first motor, a focus lens frame, a cam mechanism and a second motor. The screw rod is movably disposed on the base. The first motor is connected to the screw rod and rotates the screw rod. The focus lens frame bearing a focus lens is connected to the screw rod and moved along the screw rod. The cam mechanism abuts an end of the screw rod. The second motor drives the cam mechanism to move the screw rod so as to move the focus frame. The resolution ability of the cam mechanism is smaller than that of the screw rod.
