Summary: | The utility model relates to a transmission mechanism for a base station antenna. The transmission mechanism includes a motor, a screw driven by the motor, a movable element movably mounted on the screw, the movable element configured to move in an axial direction of the screw upon rotation of the screw, and a link engagement element configured to engage the screw in the axial direction of the screw. The connecting rod joint element is fixedly connected with the movable element and can axially move together with the movable element; the transmission mechanism comprises a cylindrical limiting element, the end face of the limiting element is provided with a limiting part used for limiting the movable element to the zero point position, and the inner surface of the limiting element is of a polygonal structure. And the polygonal structure is suitable for being matched with a polygonal part arranged on the screw rod so as to prevent the screw rod from rotating relative to the limiting element.
