The vertical rod 8 is arranged vertically, and the rotating tube 9 is rotatably mounted above the vertical rod 8, and the rotating tube 9 passes through the vertical rod 8. A connecting rod 16 is connected to one end of the rotating tube 9, and an adjusting screw 6 is threadedly mounted on the other end. The end of the connecting rod 16 is fixedly connected to the lining plate 11, and the adjusting screw 6 is threadedly penetrated into the interior of the rotating tube 9, and the penetrated end is rotatably connected to the driving rod 7, and the driving rod 7 slides horizontally along the interior of the rotating tube 9; the connecting rod 16 is fixed at the center of the circle of the lining plate 11, and the connecting rod 16 has a connecting groove 15 at one end facing the rotating tube 9. The end of the rotating tube 9 penetrates the inner side of the connecting groove 15, and a rotating hole 12 is opened through the rotating tube 9, and a fixing hole 17 corresponding to the rotating hole 12 is opened on the connecting rod 16. A rotating shaft 13 is rotatably passed through the interior of the rotating hole 12, and the rotating shaft 13 is fixedly connected to the fixing hole 17. The outer fixed sleeve of the rotating shaft 13 is provided with a driving gear 14, which is rotatably arranged inside the rotating tube 9, and the driving rod 7 is located above the driving gear 14, and the bottom end surface of the driving rod 7 is protruding with multiple groups of gear blocks adapted to the driving gear 14. The flange to be inspected is placed on the lining plate 11, which is coaxially distributed with the flange, and the lining plate 11 penetrates into the central hollow of the flange.

[0025] Reference Figure 4 , support blocks 10 are provided on the upper surface and the bottom end surface of the lining disk 11. The support block 10 slides into the interior of the lining disk 11, and one end of the support block 10 that penetrates into the lining disk 11 is fixedly connected to a driving block 19. Two sets of guide grooves 20 are vertically opened on the outer wall of the lining disk 11, and one end of the driving block 19 extends out of the guide groove 20. The driving blocks 19 are symmetrically distributed up and down with the center of the lining disk 11 as the center of the circle, and the part of the driving block 19 located inside the guide groove 20 is connected to a spring 18.
