Foldable bracket

A foldable stand, comprising:

• a leg bracket assembly;
• a pulling-rod assembly comprising a pulling-rod assembly first end and a pulling-rod assembly second end that are opposite to each other, and the leg bracket assembly being coupled to the pulling-rod assembly first end;
• and
• a supporting assembly foldably coupled to the pulling-rod assembly second end, and the supporting assembly is configured to move between an unfolded state and a retracted state;
• wherein the supporting assembly comprises at least a main bracket, a first connecting rod assembly, and a second connecting rod assembly;
• the main bracket being rotatably coupled to the pulling-rod assembly second end via a rotating shaft;
• the first connecting rod assembly being rotatably coupled to the main bracket;
• and the second connecting rod assembly is coupled to the main bracket about a center of the second connecting rod assembly;
• wherein in the unfolded state, the first connecting rod assembly and the second connecting rod assembly being unfolded and forming a supporting surface;
• and in the retracted state, the first connecting rod assembly and the second connecting rod assembly are affixed with the main bracket, and the first connecting rod assembly, the second connecting rod assembly, and the main bracket define a rod-shaped structure.
