Socket and spigot joint type steel pipeline capable of being flexibly connected

The utility model discloses a flexibly connected socket type steel pipeline, which comprises a pipeline, the pipeline comprises a main pipeline and a secondary pipeline, firstly, the main pipeline is in threaded connection with the secondary pipeline, at the moment, a rubber ring is positioned at the joint of the inner walls of the main pipeline and the secondary pipeline, at the moment, a connecting structure is sleeved at the joint of the outer rings of the main pipeline and the secondary pipeline, and at the moment, the main pipeline is connected with the secondary pipeline. The clamping plates are pushed through the connecting springs, so that the distance between the clamping plates is reduced, and therefore the pipeline clamping device can adapt to various pipelines with different diameters, meanwhile, the distance between the clamping plates is reduced, the pipelines can be clamped and connected more stably, the clamping plates are completely attached to the outer rings of the pipelines at the moment,
