Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", 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 description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a fixed knot constructs is connected to chair base, is including hiding cover 2, seat support 1 and chair pole 3, hides cover 2 and has seted up a plurality of mounting groove 201, and wherein mounting groove 201 contains and is used for seat support 1 and chair pole 3 to be connected used screw 4, and seat support 1 is located and hides 2 tops of cover, and chair pole 3 is located and hides 2 below of cover.

Further, the hidden sleeve 2 comprises an air bag 202, an upper limiting block 203 and a lower limiting block 204, the air bag 202 is disposed between the mounting slots 201, and the upper limiting block 203 and the lower limiting block 204 are respectively disposed at the upper end and the lower end of the inner side of the hidden sleeve 2.
