By sleeve-arranging the two arc-shaped protection blocks 11 on the outside of the pipeline, and then fixing the two mounting plates 14 through the connecting bolts 15, the two arc-shaped protection blocks 11 can be fixed on the outside of the pipeline to protect it.

[0026] Reference Figure 1 - Figure 2 , the connecting block 13 is an arc-shaped structure.

[0029] Reference Figure 1 - Figure 3 A first guide groove 18 corresponding to the first slide bar 22 is provided on the outer side of the arc-shaped protective block 11, and a first guide block 23 is slidably installed on the inner side of the first guide groove 18, and the first guide block 23 is fixedly connected to the corresponding first slide bar 22; a first spring 24 is sleeved on the first slide bar 22, and the first spring 24 is located on the outer side of the arc-shaped protective block 11, and the diameter of the first spring 24 is larger than the inner diameter of the first guide groove 18.

[0030] Reference Figure 1 - Figure 3 The top ends of the two protection plates 21 are both hinged with a connecting plate 25, and the two connecting plates 25 are rotatably connected via a pin shaft.

[0031] The two protective plates 21 can protect the outer side of the arc-shaped protective block 11, and the two connecting plates 25 can protect the top of the arc-shaped protective block 11; when the protective plate 21 is impacted by external force, the protective plate 21 will transfer the impact force to the first slide bar 22, which makes the first slide bar 22 slide into the first guide groove 18.
