[0007] Furthermore, the end support portion includes support airbags arranged at intervals along the central axis direction of the telescopic rod of the telescopic push rod, and the support airbags are annular and are configured to deform along the radial direction thereof.

[0008] Furthermore, the external clamping unit includes clamping members arranged opposite to each other, and an arc-shaped clamping working surface is arranged on one side of the clamping members close to each other, and the clamping working surface extends to a predetermined length along the central axis direction of the pipeline; the lifting frame is respectively equipped with fixed side plates at the middle positions on both sides along the width direction, and the fixed side plates are movably penetrated by support screws, and the support screws are threadedly connected to the fixed side plates, and the support screws are located at one end on the inner side of the fixed side plates and are connected to the clamping members for adjusting the distance between the clamping members.
