The elastic body 3 can be a rubber material with buffering and energy absorbing properties, or a hydraulic oil is filled in the elastic body 3. In the example where the elastic body 3 is a rubber material, the rubber material is not adjustable in rigidity.

When the supporting device 100 is under the action of pulling force, the stud 65 bears the action of pulling force, and the center of the spherical pad 61 is provided with threads, so that after the stud 65 is screwed into the bolt hole, the spherical pad 61 can be fully contacted with a supported object through the threads of the stud 65, and when the supporting device 100 is under the action of pulling force, a part of pulling force can be transmitted to the piston 62 to play a role of buffering. When the supporting device 100 is under pressure, the pressure can be transmitted to the spherical head 64 and the cylinder 63 through the bottom plate 2, so as to play a role of buffering.
