Claim:
1. A topple-proof buffering structure for a chair, comprising: an elastic supporting plate, connected to a fixing substrate of a chair leg of the chair, two deforming buffering portions are respectively arranged at two ends of the elastic supporting plate and protruded from an outer side of the fixing substrate; a seat fixing plate, assembled to a bottom side of a seat of the chair; and a plurality of flexible pillars, each end thereof has a bolt member, a screw hole member, and a limit screw for connecting the bolt member with the screw hole member which are embedded therein, the bolt member has an embedding end and an outer threading section protruded from one end of the corresponding flexible pillar, an inner screw hole is arranged at a surface of the embedding end, the outer threading section is assembled to the seat fixing plate, the screw hole member has a screw hole for assembling to the corresponding deforming buffering portion, one end of the screw hole member opposite to the screw hole has a small diameter hole and a retaining lip, the retaining lip is arranged between the screw hole and the small diameter hole and adjacent to the small diameter hole, the limit screw is passed through the small diameter hole of the screw hole member and screwed in the inner screw hole of the bolt member, the limit screw is used for connecting the screw hole member with the bolt member, and supporting the flexible pillars not to be damaged and broken due to elastic deformation, the limit screw of each flexible pillar is screwed in and out the inner screw hole, a buffering deformation of each flexible pillar is adjusted based on a distance change between a screw head of the limit screw and the retaining lip.
