The double inclined surface setting can facilitate the rotation of the rotating plate 405, thereby playing a role in pre-positioning. The inner wall of the limiting column 504 is threadedly connected with a bolt 502. The setting of the bolt 502 can play a role in limiting and fixing. One end of the connecting spring 503 is fixedly connected to the inner wall of the limiting block 501, and the other end of the connecting spring 503 is fixedly connected On the outer wall of the limiting column 504, the outer wall of the limiting column 504 passes through and is slidably connected to the inner wall of the limiting block 501.

When the length of the multiple sets of telescopic frames 402 is slightly smaller than the inner diameter of the pipeline, the end of the telescopic frame 402 is The L-shaped part will be hung above the pipeline (the pipeline is placed vertically), the bolt 502 will be reset to complete the fixation, and then the electric telescopic rod 406 will be started. The bottom end of the electric telescopic rod 406 will drive the fixed plate 408 to move downward, the length of the telescopic hose 407 will be lengthened, and the fixed plate 408 will move to the bottom of the pipeline.
