In this embodiment, the plurality of rotating structures are sequentially connected in series through the rotating column 130, the structure is simple, and the rotating column 130 can provide a certain supporting function, so that the strength of the folding structure 100 is improved.

Preferably, the rotation column 130 has a first end portion protruding out of the first upper portion 111 and a second end portion protruding out of the second upper portion 121, and nuts are respectively screwed on the first end portion and the second end portion to define a distance between the two nuts, so that the connection between the rotation column 130, the first upper portion 111, the first lower portion 113, the second upper portion 121, and the second lower portion 123 is stable.

Further, in one embodiment, referring to fig. 1-4, the first support leg 110 extends along a first line and the second support leg 120 extends along a second line, the first line and the second line being staggered.
