[0025] The fixing structure 3 comprises a cross bar 31 fixedly installed on the upper clamping plate 11 and the lower clamping plate 12, and an arc-shaped plate 32 fixedly installed on the cross bar 31. The first screw rod 33 is threadedly installed on the arc-shaped plate 32. The arc-shaped plate 32 is rotatably installed on the housing 34 through the bearing seat 35 at the end of the arc-shaped plate 32. The housing 34 is fixedly installed with the lug plate 36 at both ends. The lug plate 36 is installed with the bolt 37. The upper clamping plate 11 and the lower clamping plate 12 are threadedly installed with the second screw rod 38. The second screw rod 38 extends through the upper clamping plate 11 to the other end of the upper clamping plate 11. The second screw rod 38 is rotatably installed with the push plate 39 at one end. The second screw rod 38 is fixedly installed with the rotating disc at the other end away from the push plate 39. The push plate 39 is in contact with the surface of the pipeline 2 at one side.

The bidirectional screw rod 44 is threadedly installed with the nut 46 at both ends.

[0029] Specifically, the handle 45 drives the bidirectional screw rod 44 to rotate in the adjusting structure 4, thereby driving the upper clamping plate 11 and the lower clamping plate 12 to fix the end of the pipeline 2.
