A gear ring 12 is provided in the input direction of the second gear 17, and a handle 9 is detachably connected to the gear ring 12. When the pipe segment needs to be repaired, the mobile frame 1 is first moved as a whole to the pipe segment position, and then the mobile frame 1 on one side is pushed, and the auxiliary rod 2 can drive the inner ring 7 to a vertical state through the pull rod 19, and the top plate 3 can be arranged in a vertical state as a whole, and then the handle 9 is turned, and the handle 9 can drive the gear ring 12 to rotate as a whole. After the gear ring 12 rotates, the rack 13 can be controlled, and the rack 13 can drive the top plate 3 to move to the pipe segment position, so that one circle of the pipe segment is fixed. When the pipe segment is repaired, the pipe segments at other positions will not be damaged, thereby protecting the pipe segments at other positions.

The support 16 is rotatably connected with the movable rod 11, and the two ends of the movable rod 11 are respectively located on both sides of the support 16. The movable rod 11 can be restricted by the setting of the support 16, and the movable rod 11 can be rotated at the position of the support 16. When the movable rod 11 rotates, it will not be displaced, thereby ensuring that the positions of the first gear 10 and the second gear 17 will not change.

[0022] One end of the movable rod 11 is detachably connected to the second gear 17, and the other end of the movable rod 11 is detachably connected to the first gear 10, and the first gear 10 and the second gear 17 are coaxially arranged. When the first gear 10 and the second gear 17 are installed on the movable rod 11, the second gear 17 will also rotate after the first gear 10 rotates, thereby ensuring the linkage of the first gear 10 and the second gear 17.

[0023] The other end of the socket 18 is rotatably connected to a swivel 8, the cross section of which is L-shaped as a whole, and a gear ring 12 is welded on the bent end of the swivel 8. The swivel 8 can be restricted by the socket 18, and the swivel 8 can be rotated on the socket 18, and the rotation of the gear ring 12 can be realized when the swivel 8 rotates.

One end of the pull rod 19 is connected to the auxiliary rod 2, and the other end of the pull rod 19 is connected to the inner ring 7. When the auxiliary rod 2 moves, the inner ring 7 will be pulled by the pull rod 19 at the same time. After being pulled by the pull rod 19, the inner ring 7 will be arranged vertically; S2: After the pulling is completed, the staff rotates the handle 9. When the handle 9 is connected to the swivel 8, the swivel 8 will rotate due to the rotation of the handle 9. During the rotation of the swivel 8, the connected gear ring 12 will be driven to rotate. The gear ring 12 will drive the meshing first gear 10 when rotating. The first gear 10 and the second gear 17 are connected to the movable rod 11. The second gear 17 will rotate with the first gear 10. When the second gear 17 rotates, it will drive the rack 13 to move outward.
