In the era of ergonomics, a comfortable chair must be equipped with many adjustment devices with different functions, such as the lifting adjustment mechanism of the seat seat, the front and rear adjustment mechanism of the seat cushion, and the inclination adjustment mechanism of the seat back. It is very common and has practical functions; and because these adjustment devices are usually controlled by wires, various single control levers can be used to centrally set under the seat for user operation (the traction of the wires can be used) The extension device is at the bottom of the seat), so often a fully functional chair must be provided with many operating levers under the seat for users to choose different functional operations.

According to the above structural form, although the control levers with different functions are arranged under the seat for the user to touch and operate, but too many control levers make it difficult for the user to remember the correct position, so the user often adjusts them. All must leave the seat to find the control lever, which not only deviates from the design intention that the control lever is arranged under the seat seat (its design purpose is to allow the user to sit on the seat and directly operate); in addition, under the seat Setting too many control levers also affects the aesthetics.

At the same time, Chinese patent CN202919594U discloses a spherical wire control mechanism of a chair adjustment device. The front end of the wire connector is spherical, and the wire connector can be movably embedded in the installation cavity. , due to the wide range of movement of the wire connector, it is difficult for the user to accurately control the required mechanism, and often pull multiple wires at the same time, so that other mechanisms that have been set will change again, so that the user needs to adjust again.
