Integrated cushion block

The invention relates to an integrated cushion block. The integrated cushion block comprises a first connecting rod, a second connecting rod connected with the first connecting rod and a plurality ofcushion blocks. Connecting holes are formed in the middles of the cushion blocks, and each cushion block is provided with a first groove and a second groove. The distance between the bottom of each first groove and the center axis of the corresponding connecting hole is H1, the distance between the bottom of each second groove and the center axis of the corresponding connecting hole is H2, and H1is larger than or smaller than H2. Part of the cushion blocks are mounted on the first connecting rod through the connecting holes. After the cushion blocks are mounted on the first connecting rod, the first grooves of the cushion blocks are in the same direction and are perpendicular to the plane where the first connecting rod and the second connecting rod are located. The other part of the cushion blocks are mounted on t
