Detailed Description

The present invention will be described in further detail with reference to the following examples and accompanying drawings.

It should be noted that in the description of the present invention, the terms "horizontal", "inside", "outside", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

Fig. 1 and 2 are developed views of a first embodiment of the present invention; fig. 3 shows a folded state of the first embodiment of the present invention. As shown in fig. 1 and 2, the rotary folding stool comprises an outer frame 1, a middle frame 2 and a seat board 3.
