The two upper support arms 3 in the upper casing 2 are arranged oppositely. The lower cavity of the lower casing 4 is fixed with a lower ear handle 401 on both sides, and the lower ear handle 401 is hinged with a lower support arm 5. The two lower support arms 5 in the lower casing 4 are arranged oppositely.

[0019] The two compression discs 6 are arranged oppositely, and a compression spring 7 is connected between the two compression discs 6. When the upper connecting plate 1 is subjected to pipeline pressure, the pressure is transmitted to the compression disc 6 through the upper casing 2 and the upper support arm 3.

When the upper connecting plate 1 moves downward, the included angle between the upper support arm 3 and the lower support arm 5 is reduced, at this time, the compression disc 6 on the left and right sides moves to the middle and moves towards each other to compress the compression spring 7, and the compression force of the compression spring 7 is the force for bearing the pipeline load. The product is made into a cuboid structure, so that the size can be reduced, and it is convenient to use in some narrow environment. When the pipeline vibrates, the vibration is transmitted to the upper support arm 3, the lower support arm 5, the compression disc 6 and the compression spring 7 through the upper connecting plate 1, the upper shell 2 and the upper lug 201, and these components are in the damping liquid 8.
