[0002] Business class seats are seats provided for business passengers on high-speed trains. Compared with ordinary seats, business class seats have more adjustment functions in their design; for example, they are usually equipped with armrests that can be raised and lowered to improve riding comfort.

[0003] Currently, the armrest height adjustment method on business chairs sometimes uses a steel cable lifting structure, and most of these are single-sided steel cable structures, meaning that only one side of the steel cable is used to pull the armrest up and down. This single-sided steel cable structure presents the following technical problems:

[0004] The handrail lifting operation relies on the pulling of a steel cable on only one side, which will result in relatively poor balance of the handrail lifting system. During the lifting process, the steel cable on one side may be affected by uneven tension distribution, resulting in unstable lifting and easy tilting or swaying.

[0005] Therefore, how to solve the above-mentioned technical problems is a technical problem that those skilled in the art urgently need to solve.
