One side of the square stool surface 301 has a square stool slide groove 302 and the other side has a square stool slide rail 303. Square stool legs 304 are mounted on the square stool surface 301. The lengths of the square stool legs 304 mounted on the four square stool surfaces 301 are different and increase sequentially. One end of each square stool leg 304 is provided with a square stool leg seat 305.

[0036] The working principle of this utility model is as follows:

[0037] This utility model can be folded, unfolded and transformed into various forms. The lower sofa 1 and the upper sofa 2 can rotate with each other through the hinge 5 and form two states. When the lower sofa 1 and the upper sofa 2 are in the folded state, the upper sofa 2 is placed on the lower sofa 1. The height adjustment base plate 102 can be pulled out from the height adjustment cabinet 101 on the lower sofa 1. The base plate folding leg 103 can be pulled out from the height adjustment base plate 102 to support the height adjustment base plate 102 and thus support the backrest 201. The base plate limiting groove 104 can support the backrest support frame 203. The backrest support frame 203 is used to support the backrest 201. The backrest 201 is supported by the armrest of the upper sofa 2, the backrest round groove 205 and the backrest support frame 203 respectively. The backrest 201 can adjust the tilt angle.

[0038] When the lower sofa 1 and the upper sofa 2 are unfolded, the upper sofa 2 is placed on the ground, the folding legs 103 of the base plate are retracted into the height-adjustable base plate 102, the height-adjustable base plate 102 is retracted into the height-adjustable cabinet 101, the backrest 201 is stored in the backrest limiting block 204, and the backrest support frame 203 is folded on the backrest 201. At this time, the furniture has a larger usable area but no backrest.

[0039] Simply open the cabinet door 402, and the fan stool 3 can be pulled out from the cabinet 4 at any time. The fan stool 3 can be spirally opened around the square stool pivot 306, and the square stool slide 302 and square stool slide rail 303 play a guiding role in unfolding and folding. After opening, the square stool legs 304 on the square stool surface 301 can be unfolded. The square stool leg base 305 plays a role in increasing the support stability. Since the height between the square stool surfaces 301 after opening is stepped, the length of the square stool legs 304 also increases in a stepwise manner to balance the height of the fan stool 3. This design also makes it easy to store the square stool legs 304 when folded. A table mat can be placed on the fan stool 3 to use it as a small table or coffee table of this utility model.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
