Furthermore, the bending included angle between the seat surface installation part and the supporting part is alpha, and the size of the alpha is 100-130 degrees.

When the angle alpha is 90 degrees, the supporting part is vertical to the seat surface mounting part, and the chair legs are vertical to the ground, and the structure of the chair is the same as that of a common chair. When α is greater than 90 °, the legs lean outward, which increases the resistance of the chair to tipping. When the conventional chair is impacted leftwards, the chair rotates by taking the lower ends of the two left chair legs as supporting points to form a tilting tendency, the anti-tilting moment is provided by the overall gravity center of the chair, and if the gravity center exceeds the supporting points, the chair is completely tilted. The chair legs of the utility model are arranged obliquely, so that the gravity center of the chair is farther away from the pivot, and the anti-falling capability is enhanced. However, the angle α cannot be set too large, which may cause a large shearing force to the joint of the support portion and the seat mounting portion, and may cause breakage of the joint.

Furthermore, a pulley mounting part is formed by bending the lower part of the supporting part, the bending included angle between the pulley mounting part and the supporting part is beta, and alpha + beta =270 degrees; the lower end of the pulley mounting part is provided with a universal wheel.

Because the supporting part is obliquely arranged, the angle of the pulley needs to be adjusted to align the pulley with the ground, and the pulley mounting part is perpendicular to the ground when the angle is alpha + beta =270 degrees through simple mathematical calculation.

Furthermore, the bending connection part between the supporting part and the seat mounting part and the bending connection part between the supporting part and the pulley mounting part are provided with reinforcing sleeves.

Because the characteristic of the bending connection part can cause shearing force to the connection point when bearing pressure, in order to improve the stability and the service life of the connection part, a reinforcing sleeve is arranged at the bending part.
