High-stability handrail assembly

The high-stability handrail assembly comprises a base and a handrail handle located above the base, limiting hole grooves are formed in the two sides of the top of the base, sliding cylinders are connected to the bottoms of inner cavities of the limiting hole grooves in a sliding mode, and rectangular plates are connected to the interiors of the sliding cylinders in a sliding mode; the tops of the two rectangular plates are fixedly connected with the two ends of the handrail handle respectively, a plurality of limiting holes are formed in the front portions of the rectangular plates, and limiting mechanisms matched with the limiting holes are arranged on the front portions of the sliding barrels. According to the high-stability handrail assembly, by pulling a baffle outwards, the baffle drives a limiting rod to move, the limiting rod can be disengaged from a limiting hole in a rectangular plate, the limiting rod does not clamp the limiting rectangular plate any more, then a handrail handle is pressed downward
