As to the utility model discloses a further limit again: the adjusting piece is a nut fixedly arranged on the outer wall of the support and concentrically arranged with the adjusting hole, and the bolt is connected to the nut through threads.

As a further limitation to the present invention: the observation hole is arranged in the middle of the bracket along the length direction.

As to the utility model discloses a limit: the adjusting holes are symmetrically arranged on two sides of the observation hole.

As another limitation to the present invention: and the two ends of the observation hole are coincided with the two sides of the bracket.

Since the technical scheme is used, compared with the prior art, the utility model, the beneficial effect who gains lies in:

(1) the utility model is suitable for the small-caliber pipeline butt prefabrication work which is carried out under the conditions of large butt-joint workload, less technical work types and the like, has simple and safe operation, accurate butt-joint and high welding efficiency, and adjusts the concentricity of the pipeline through the indentation amount of the bolt on the inner wall of the groove of the bracket so as to meet the requirement of a welded junction and avoid the phenomena of folding, staggered joint, uneven welding seam and the like of the welded junction;

(2) the utility model discloses a bottom of support is equipped with the observation hole, not only can observe the pipeline and to the condition of mouthful, can also weld the pipeline bottom, reduces to convert the pipeline to the support top once more and carries out welded operation, makes its operation simpler.

To sum up, the utility model is simple in operation safety, accurate, the welding is efficient to mouthful, is applicable to all pipeline welding and is to mouthful device.
