[0032] Working principle: Step 1: First, lay the gas pipeline in the trench, and then insert the bolts into the threaded holes on the flange 1 to connect it to the gas pipeline on one side. Since the bellows 11 is not installed at this time, there is a large space and it is easy to install the flange 1. After the flange 1 and the gas pipeline are installed, put the bellows 11 between the gas pipelines, and use a wrench to turn the nut 4 on one side. The nut 4 rotates on the screw rod 9, driving the rotating disk 3 to move toward the side of the flange 1, and the rotating disk 3 drives the cylinder 16 to move in the fixed disk 2. Since the spring 17 is extended at this time, the cylinder 16 drives the second round rod 14 to move through the spring 17, and the second round rod 14 drives the pull rod 12 to move through the first round rod 13. At this time, the pull rod 12 enters the inside of the round hole 18 through the opening 19; As the pull rod 12 moves, when the pull rod 12 contacts the flange 1, the pull rod 12 stops the first round rod 13 and the second round rod 14 from moving. At this time, the cylinder 16 continues to move, which will squeeze the spring 17, and the cylinder 16 drives the second squeezing ring 21 to move toward the squeezing rod 15. The first squeezing groove 22 on the second squeezing ring 21 squeezes the squeezing rod 15. At this time, the squeezing rod 15 rotates 45 degrees, and the squeezing rod 15 drives the pull rod 12 to rotate in the round hole 18 through the second round rod 14 and the first round rod 13. When the nut 4 cannot be turned, start to turn the nut 4 in the reverse direction. The nut 4 drives the cylinder 16 to move in the reverse direction through the rotating disk 3. At this time, the pull rod 12 is stuck inside the flange 1. The cylinder 16 drives the first extrusion ring 20 to move in the reverse direction, and the spring 17 starts to stretch. At this time, the second extrusion groove 23 on the first extrusion ring 20 starts to squeeze the extrusion rod 15. The extrusion rod 15 rotates 45 degrees again. The extrusion rod 15 drives the pull rod 12 to rotate 45 degrees again. As the nut 4 moves, the pull rod 12 is gradually tightened to complete the installation of the fixed disk 2 and the flange 1.

[0033] Step 2: Place the fixing frame 101 above the gas pipeline, and then first control the second electric telescopic rod 1013 to contract, drive the second fixing frame 1014 to move, and the second fixing frame 1014 drives the second slide groove 1016 to move, drive the clamping claw 1017 to slide in the first slide groove 1015, and the clamping claw 1017 clamps the gas pipeline on the other side; Then, the first electric telescopic rod 1011 is controlled to retract, and the first electric telescopic rod 1011 drives the first fixed frame 1012 to move. At this time, the clamping claw 1017 drives the gas pipeline to move toward the side of the bellows 11.

[0034] Step 3: By turning the nut 4 on the other side, the gas pipeline on the other side is connected to the bellows 11 through the fixed plate 2. After all the installation is completed, pull the first ratchet 7 and the second ratchet 10. The first ratchet 7 and the second ratchet 10 drive the telescopic rod 6 to extend, and the first ratchet 7 and the second ratchet 10 are adsorbed and engaged together. At this time, the first ratchet 7 and the second ratchet 10 lock the nut 4 through the telescopic rod 6 and the support plate 5 to prevent loosening.

[0035] Step 4: When disassembly is required, first pull the first ratchet 7 and the second ratchet 10 to separate them, and then rotate the nut 4 on one side. At this time, the installation steps are the same. The nut 4 is first rotated toward the flange 1 side, and the pull rod 12 will rotate 45 degrees in the circular hole 18, and then the nut 4 is rotated in the opposite direction. At this time, the pull rod 12 is rotated 45 degrees again, and the pull rod 12 will be pulled out from the opening 19, and then the other side can be disassembled.
