[0019] By setting up the docking mechanism, when the two natural gas pipelines are limited by the clamping components in the adjustment component 2, the personnel can start the motor 1 to rotate the bevel gear 2. At this moment, the bevel gear 2 can transmit the transmission force to the two bevel gears 1 and rotate with the transmission screws fixed in the middle of each.

Since the inner sides of the two opposite inner connecting frames 547 are respectively provided with clamping members 548, at this time, the two pairs of clamping members 548 can clamp the pipeline, and the outward expansion inclined posture of the two pairs of clamping members 548 can better adapt to pipelines of different sizes. It is worth mentioning that the placement of the pipeline in the middle of the inner rotating ring 52 on the other side is the same as the above.
