This operation is more troublesome, which greatly reduces the connection efficiency. At the same time, the bolts connecting the existing right-angle hanging plate and the ball head hanging ring will rub against the inner wall of the right-angle hanging plate due to the influence of wind for a long time, causing the galvanized layer on the outer surface of the bolt to wear, thereby reducing the corrosion resistance of the bolt and greatly reducing the service life of the bolt.
