In the process of lifting the office chair body 1, the user can also start the distance detector 62 to detect the distance between the bottom of the office chair body 1 and the distance detector 62. Then the distance detector 62 will import the detected data into the data display board 61 and display it through the data display board 61, so that the user can understand the height to which the current office chair body 1 is adjusted. In the process of sliding cooperation between the stabilizing rod 5 and the stabilizing sleeve 4, the stabilizing rod 5 will synchronously drive the limiting bar 71 to slide along the inside of the limiting groove 72. At this time, the limiting bar 71 and the limiting groove 72 will slide together to limit the maximum activity space of the stabilizing rod 5, so as to avoid the stabilizing rod 5 from being separated from the stabilizing sleeve 4, and have the ability to improve the stability of use.

[0037] To sum up: the lifting component for office chair is provided with a stabilizing rod 5. When the user uses the hydraulic rod 2 to move the office chair body 1 for lifting and adjustment, the office chair body 1 will synchronously drive the stabilizing rod 5 to move, and then utilize the sliding cooperation between the stabilizing rod 5 and the stabilizing sleeve 4 to assist in stabilizing the lifted office chair body 1, thereby solving the problem that when a lifting structure is used to support the office chair, the supporting capacity of the office chair can only be supported by a single lifting structure, resulting in the supporting strength of the office chair being affected, thereby reducing the stability of the office chair.
