The invention relates to a wall surface handrail support. The handrail support includes a bearing rack and a fixing base arranged at the tail end of the bearing rack; a locating hole is formed in thefixing base, a connection head is arranged at the top of the L-shaped bearing rack, a fixing ring is connected to the connection head, a connection port is formed in the bottom of the fixing ring, turnups facing downwards are arranged at the two sides of the connection port and clamped at the two sides of the connection head, corresponding thread holes are formed in the turnups and the connectionhead, and the fixing ring is fixedly connected with the bearing rack by using bolts to penetrate through the thread holes; the tail end of the bearing rack is provided with an insertion plate facing downwards, the side surface, corresponding to the fixing base, of the insertion plate is provided with an insertion groove which is provided with an opening facing upwards and matched with the insertion plate. The wall surface handrail support is simple in structure and independent to a handrail, and therefore when the bearing rack is damaged, only the bearing rack needs to be replaced without influencing the whole handrail, so that assembly and disassembly are pretty convenient.
