Auxiliary stabilizing device for foot stool and use method of auxiliary stabilizing device

The invention discloses an auxiliary stabilizing device for a foot stool and a use method of the auxiliary stabilizing device. The auxiliary stabilizing device comprises a hollow cavity (1) which forms a circle, at least three foot stool channels (2) which penetrate through the upper surface and the lower surface of the hollow cavity so that foot stools can penetrate through the foot stool channels, a hyperbolic tightening part (3) which is located on at least one end surface of the foot stool channel, and vent holes (4), wherein the minimum inner diameter of the hyperbolic tightening part is equal to the inner diameter of the foot stool channel, and the hyperbolic tightening part is made of an elastic material; and the vent holes (4) are formed in the side surface of the hollow cavity. The auxiliary stabilizing device has the beneficial effects that the auxiliary stabilizing device can be used after the screw rod or the sliding rod fails, the structure is simple, the hyperbolic tightening part is driven by n
