Problems solved by technology

[0002]The chair is the most common piece of furniture, generally used as a tool for resting, with a single function
Of course there are also some multifunctional chairs, such as: a kind of high-rise building life-saving ladder with chair function described in Patent No. CN202407938 Chinese Utility Model Patent, which has a chair body with a cross brace backrest, and the chair body seat The four fixed chair legs below are of multi-section telescopic structure, and the two adjacent legs of the four chair legs are equipped with a push-in type cross brace composed of two sections of pipes; the seat is box-shaped, consisting of a base and an upper cover It consists of a foldable life-saving ladder installed between the base and the upper plate cover. One end of the foldable life-saving ladder is connected to the base through a twisted shaft, and the other end is connected to the upper plate equipped with hooks for hooking buildings. Because the lifesaving ladder is placed in the seat, its length is limited by the space inside the seat, and the four chair legs are multi-section telescopic structures, the length of the chair legs is limited to a certain extent, and it is easy to shake, which affects the stability of the chair
