step 5, stretching out the porcelain disc support rod (27) of the lower support part (7) and supporting and fixing the porcelain disc support rod through the inclined support rod (24), moving the lower support part (7) to enable the porcelain disc support rod (27) to reach the height of the lower end of the position to be replaced of the suspension insulator, and supporting the porcelain disc support plate (22) at the end part of the lower support part at the bottom of the porcelain disc connected with the section to be replaced of the suspension insulator;

and 6, removing connection of the upper end and the lower end of the section to be replaced of the suspension insulator, hanging the section to be replaced to the ground through a hanging tool, hanging the new section to the corresponding height, moving the new section to the position where the vacancy of the section to be replaced is removed by the suspension insulator, supporting the porcelain disc at the uppermost end of the new section by a porcelain disc support plate (22) of an upper supporting part (3), and finally connecting the upper end and the lower end of the new section with the original suspension insulator.
