The invention relates to a handrail armrest bracket. The handrail armrest bracket comprises a base group and a sleeve group, the base group comprises a rectangular-shaped chassis, the chassis comprises an upper surface and a lower surface, and mounting holes are formed in the periphery of the chassis; a first annular bulge is formed on the outer edge of the lower surface of the chassis, and a second annular bulge is formed in the position, around outer rings of the mounting holes, on the lower surface of the chassis; the height of the first annular bulge and the height of the second annular bulge are the same, the lower end surfaces of the first annular bulge and the second annular bulge are provided with friction cushion layers, and meanwhile, the second annular bulge and the mounting holes are arranged in a communicating mode; and the sleeve group comprises a sleeve vertically arranged on the upper part of the chassis, the side wall of the sleeve is provided with a plurality of through holes for allowing bolts being transversely embedded, and the multiple through holes are arranged in a circumference arrayed mode. The handrail armrest bracket has the advantages of simple structure, improving of stability and wide application range.
