[0034] The outer side of top plate 6 is fixedly connected with rubber pad 7, which is tightly attached to the inner wall of the pipeline during expansion, one end of inner column 3 is rotationally connected with a starting assembly for ensuring that the inner wall of the pipeline is lifted, the starting assembly includes a rotating shaft 8, one end of the rotating shaft 8 is rotationally connected to one end of the inner column 3, pulling the rotating shaft 8 here can drive the inner column 3 to move, the outer four sides of the rotating shaft 8 are fixedly connected with a clamping block 9, a plurality of clamping blocks 9 are slidably connected with a clamping ring 10, the clamping block 9 here is used to ensure that the top plate 6 remains fixed after being expanded to the maximum circumference.
