AI Technical Summary
The current method of raising and lowering the armrests of sofas and chairs is achieved through a complex mechanical structure, which makes operation laborious and does not meet the needs of modern young people for convenient and quick use.
It adopts a pneumatic lifting structure, including an outer support, an inner support, a pneumatic rod, and a handrail. The movement of the pneumatic rod is controlled by an adjusting component, so that the handrail and the inner support are raised and lowered synchronously. Combined with the design of the pivot and guide groove, the handrail can be infinitely adjusted and rotated at multiple angles.
It achieves rapid and stable lifting and multi-angle rotation of the handrail, improving the user experience. It has a compact structure and is easy to operate, meeting modern usage needs.
