As the relatively integral support ring is made by means of providing a number of fan- shaped connecting plates, with the fan-shaped connecting plates being in intermittent arrangement to form a circular support ring, it is light in weight and saves raw materials; as a support rod is provided correspondingly beneath each fan-shaped connecting plate and is fixedly connected thereto, and such support rods are further mutually connected via the connecting rods into an integral body, it has simple structure and high strength; and as the fan-shaped connecting plates are processed separately and then assembled into the support ring, it has a simple and convenient processing procedure and low processing costs. The term "fan-shaped" refers to the arrangement of the connecting plates . on a support ring. The connecting plates themselves may have any shape, e.g. the shape of a triangle, a rectangle or any other polyangular body, or of a circle, an ellipse or even of a fan. They can be flat or bended.
[0006] As a preference, said support ring comprises 4 to 10 fan-shaped connecting plates, and said fan-shaped connecting plates are evenly distributed within the same circumferential plane. The even distribution of the plurality of fan-shaped connecting plates constituting the support ring can ensure that the centre of gravity of the support is kept balanced and stabilized, thus improving its safety and reliability in use.
[0007] Even more preferably, reinforcing plates are provided between the undersides of said fan-shaped connecting plates and the support rods . The reinforcing plates improve the connecting strength between the fan- shaped connecting plates and the support rods, and prevent the fan-shaped connecting plates from deforming.
[0008] The connecting rods can be arranged at the middle parts or the lower ends of the support rods, and as a preference, said connecting rods are horizontally fixed to the upper ends of adjacent support rods, and reinforcing rods are provided between adjacent support rods beneath said connecting rods, and an angle is formed by said reinforcing rod and said connecting rod. The accuracy of the positioning of the fan-shaped - A - connecting plates located above the support rods can be ensured and the steadiness of support and reliability thereof can be improved when the connecting rods are horizontally fixed to the upper ends of adjacent support rods; and the connecting strength among the support rods can be improved by providing reinforcing rods between adjacent support rods.
[0009] As a preference, rod-supporting bottom plates are provided on the lower end surfaces of said support rods. The rod-supporting bottom plates increase the contact areas between the support rods and the ground and ensure a steady and reliable support.
