The device is equipped with an electric push rod, a mounting block, a motor, a first gear, a second gear, a third gear and a winding rod. By controlling the telescopic height of the electric push rod and utilizing the first gear to mesh with the second gear or the third gear, a corresponding traction and winding speed is obtained to meet the winding requirements of cables of different wire diameters and avoid the need for greater winding tension due to excessive winding speed of thicker cables.
