As a further optimization of the above scheme, the vertical rod comprises a first hollow rod part and a second hollow rod part, and the first rod part and the second rod part are connected in a threaded fit manner. The length of the vertical rod can be conveniently adjusted by the aid of the first rod part and the second rod part which are connected in a threaded fit mode, and design requirements are met.

As a further optimization of the scheme, universal ball hinges are arranged at the hinged positions of the first inclined rod and the second inclined rod, the vertical rod and the left movable clamping plate; and universal ball hinges are arranged at the hinged parts of the third inclined rod and the fourth inclined rod, the vertical rod and the right movable clamping plate. The flexibility of articulated connection can be realized through the design of universal ball pivot.

Adopt a pipeline pulling device have following beneficial effect:

(1) structural design is reasonable, operation convenient to use, first down tube and second down tube through the slope setting, third down tube and fourth down tube can realize when using, arrange the pipeline both sides in earlier the clamping piece, then upwards carry and draw the ring, articulated tightening up the frame is tightened up the production to pipeline pressure and is makeed the movable clamping piece to tightly hold the pipeline because of the pull force that makes progress, it makes articulated tightening up frame and movable clamping plate and pipeline together produce the pull force that makes progress to carry the ring upwards to draw, produce the pipeline lifting effect, it produces the defeated water effect of buckling to reduce the pipeline and sink. Through the design of the pipeline fixing concave part, the movable clamping plate can be conveniently fixed with the pipeline in a matched mode, and the lifting ring structure arranged through the bolt connection can be replaced and maintained according to actual design and use requirements.

(2) The length adjustment of the vertical rod can be facilitated through the first rod part and the second rod part which are connected in a threaded fit manner, so that the design requirements are met. The flexibility of articulated connection can be realized through the design of universal ball pivot.
