When the rings forming the truncated cone spiral spring are changed from round to rectangular, the total length of the truncated cone spiral spring is kept unchanged, and the length of the short side of the vertical rectangle of each ring can be smaller than the radius of the round of each ring when the truncated cone spiral spring is horizontally placed, so that the height of the support can be effectively reduced when the truncated cone spiral spring is horizontally placed.
The invention can move along the allowed vertical direction, can limit the displacement, has definite structural action, and can adjust the stress uniformity and stability of the lower support 3 and the upper support 9 in the support by adopting the vertical lower support belleville spring 5, the vertical upper support belleville spring 7, the lower vertical conical spring 18 and the vertical conical spring 19, so that elastic acting force is generated when the upper support 9 and the lower support 1 of the support are subjected to vertical displacement, the vertical external acting force is stored and converted in an elastic potential energy mode, the vertical collision of support members is avoided, and the interaction force of external objects connected on the upper surface and the lower surface of the support is reduced.
