description The invention discloses a cable net reflecting surface developable antenna thread differential motion cable length adjusting device and adjusting method. The device comprises a differential screw barrel, internal threads with different thread pitches and the opposite turning directions are arranged at the two ends of the inner wall of the differential screw barrel, external threads matched with the internal threads at the two ends of the inner wall of the differential screw barrel are arranged on a pair of adjusting screw rods respectively, the adjusting screw rods are screwed into the two ends of an inner cavity of the differential screw barrel, and small holes in the direction of the axes of the adjusting screw rods are formed in the stretching ends of the adjusting screw rods respectively. A compression spring is arranged between the inner end faces of the adjusting screw rods inside an inner cavity of the differential screw barrel. Differential screw barrel scales are evenly distributed on the outer wall
