SUPPORTING FOOT ASSEMBLY

The invention relates to a supporting foot assembly. The supporting foot assembly includes a base having a spherical convex, a disk connected to the spherical convex, a through hole, and an internal space; a swingably fitting member having a spherical concave swingably and fittingly contacting the spherical convex of the base, a lower edge located at a lower periphery of the spherical concave, anaperture, and an upper outer edge; a prop component having a bolt passing through the through hole and the aperture, a retaining portion integrated to or combined with the bolt and located in the internal space of the base so as to prevent the bolt from completely departing from the through hole of the base; and a nut screwed to the bolt of the prop component to abut against the upper outer edge of the swingably fitting member. Alternatively, another supporting leg assembly is characterized in that the nut is directly and integrally connected to the swingably fitting member. Through cooperation of the spherical convex
