[0002] To fully satisfy people's car riding experience, a lifting mechanism is usually used to adjust the height of the car seat. Although existing lifting mechanisms for car seats can meet the basic needs of lifting and adjusting car seats, after the lifting and adjusting structure completes the height adjustment of the load-bearing structure, it still continues to support the car seat body. The lifting and adjusting structure will directly bear non-vertical forces. When subjected to non-vertical tilting forces from the car seat body, the lifting and adjusting structure is easily deformed and damaged by the tilting force, thereby affecting the stability and service life of the lifting mechanism.

[0003] For example, publication number CN 213056786 U is a lifting mechanism for a car seat. In the technical solution of this patent, the height of the scissor lift platform is adjusted by a worm gear mechanism, thereby achieving adjustment of the height of the car seat.
