Compare with among the prior art to mouthpart, but this application to mouthpart is coaxial when guaranteeing two sections pipelines butt joint through locating lever 200 and gag lever post 300 along radial synchronous movement, no longer is limited by the size of pipeline 500 external diameters, therefore application scope is wider.

In this embodiment, the support sleeve 100 is formed by splicing two support plates 110 symmetrically arranged.

Specifically, the two ends of the support plate 110 are not provided with the connection holes 114, the bolt 120 passes through the connection holes 114 to fixedly connect the two support plates 110 together and enclose a space that can circumferentially cover the butt joint of the two segments of the pipeline 500, and the butt joint is exposed at the observation groove 111 to facilitate observation of the butt joint distance and welding operation.

In the present embodiment, the support plate 110 has a semicircular structure along a cross section.

Specifically, the two support plates 110 may enclose the support sleeve 100 in a cylindrical structure, so as to facilitate adjustment of the distance between the docking port and the observation groove 111, and when the support sleeve 100 is coaxial with the pipeline 500, the distance between the docking port and the observation groove 111 is the same, so as to facilitate the welding operation.
