The outer protection rod 5 and the deformed metal block 7 constitute a whole. Under normal circumstances, the deformed metal block 7 bends and deforms, and the protruding block drives the next one to continue bending. The outer protection rod 5 rotates along the center axis of the movable shaft 6 under the action of the movable shaft 6, so that the whole is close to the pipeline, etc., and the outer surface of the cylindrical structure is clamped to complete the fixation of the clamping body 1, and then the main support piece 2 adjusted in position is fixed.
