Fixed blocks 5 are fixedly connected to both ends of the surface of the U-shaped handrail 1. A receiving cylinder 13 is vertically fixedly connected to the bottom of the fixed blocks 5. A vertical rod 9 is pulled out from inside the receiving cylinder 13. A support block 10 is fixedly connected to the bottom end of the vertical rod 9. An adjustable handrail 11 is fixedly connected between the two support blocks 10.

[0022] A boss 6 is fixedly connected to the bottom of the front side of the receiving cylinder 13. A bolt 7 is provided on the boss 6. The inner end of the bolt 7 extends rotatably into the inner cavity of the receiving cylinder 13 and abuts against the side wall of the vertical rod 9. A torsion handle 8 is fixedly connected to the outer end of the bolt 7.

[0023] After turning the handle 8, the bolt 7 can be moved. After the inner end of the bolt 7 is separated from the surface of the vertical rod 9, the vertical rod 9 can move telescopically inside the receiving cylinder 13, thereby adjusting the height of the handrail 11 to facilitate adaptive height adjustment for different people.
