The length of the connection post 403 gradually decreases from the connection post 403 between the base 1 and the elastic sheet 201 adjacent thereto to the connection post 403 connected to the mount 3 and the elastic sheet 201 adjacent thereto. Since the more weight the connection post 403 closer to the base 1 needs to carry, the less weight the connection post 403 closer to the mount 3 needs to carry, the length of the connection post between the base 1 and the elastic sheet 201 adjacent thereto is longest, and the length of the connection post 403 of the mount 3 and the elastic sheet 201 adjacent thereto is shortest, and the length of the connection post 403 between the adjacent two elastic sheets 201 decreases from bottom to top.
Compared with the vibration isolation support in the embodiment 1, the vibration isolation support has the advantages that the structure of the elastic sheet 201 is simpler, the processing and manufacturing difficulties are low, and the production cost is lower.
