The fixed handle 130 can... Grasp the handrail end of the staircase to firmly fix the upper extension rod to the handrail end; support rod 200 is used to fix the upper extension rod assembly 100 and the middle extension rod assembly 300, so that they are in the same direction; the middle extension rod assembly 300 is suitable for use; tee sleeve 310 is used to fix the lower handrail 320 to the support rod 200; first pipe clamp 330 is used to connect the support rod 200 to the support part 800 of the staircase; during use, first rotate the universal assembly 120 to align the fixing handle 130 with the handrail of the staircase for installation, and then install the first pipe clamp 330 on the support part 800 of the staircase. There is no need to adjust the production according to different sizes of staircases. The installation is simple, which greatly improves the convenience and wide applicability of installing barrier-free facilities and significantly improves the quality of life of special groups such as the elderly and disabled. This technology can adapt to stairs of different heights, and the installation process is simple and quick, requiring no complicated construction. This reduces the difficulties encountered in the installation of existing barrier-free facilities, significantly improves the ease of use and accessibility of barrier-free facilities, and provides a safer, more convenient and comfortable travel environment for more people with special needs.

[0048] Specifically, the easy-to-install barrier-free safety handrail also includes a lower extension rod assembly 400, which includes an elbow sleeve 410, a fixed rod 420, and a second pipe clamp 430.
