1. A photography stand, comprising:
a central pipe, wherein a top of the central pipe is configured to mount photographic equipment;
a supporting frame connected to the central pipe and provided adjacent to a bottom of the central pipe, wherein the supporting frame moves relative to the central pipe along an axial direction of the central pipe, the supporting frame is unfolded when moving along the axial direction of the central pipe toward the bottom of the central pipe by a preset distance and then moving continuously toward the bottom of the central pipe, and the supporting frame is folded when moving along the axial direction of the central pipe toward the top of the central pipe, and wherein the supporting frame comprises a sliding seat and a plurality of supporting legs; the sliding seat is slidably sleeved on a periphery of the central pipe; an end of each supporting leg of the plurality of supporting legs is rotatably connected to the sliding seat; the plurality of supporting legs are arranged alternately on a periphery of the sliding seat; when each supporting leg moves with the sliding seat along the axial direction of the central pipe toward the bottom of the central pipe by the preset distance and then moves continuously toward the bottom of the central pipe, each supporting leg rotates away from the central pipe and is unfolded; and when each supporting leg moves with the sliding seat along the axial direction of the central pipe toward the top of the central pipe, each supporting leg rotates toward the central pipe and is folded; and
a bushing, wherein the bushing is sleeved on the periphery of the central pipe; the sliding seat drives the plurality of supporting legs to extend out of the bushing through a bottom opening of the bushing and to unfold; and the plurality of supporting legs in a folded state are retracted and stored in the bushing through the bottom opening of the bushing;
wherein a plurality of first openings are formed at a bottom of the bushing; the plurality of first openings are in one-to-one correspondence with the plurality of supporting legs quantitatively; the plurality of first openings are arranged alternately along a circumference of the bushing; and the plurality of supporting legs penetrate through the plurality of first openings, such that the plurality of supporting legs are unfolded on a periphery of the bushing.
