Integral expansion bolt fastened in wall

The utility model belongs to the technical field of fastening devices, and particularly relates to an integral expansion bolt fastened in a wall. The expansion bolt is characterized in that the transmission rod portion is sleeved with a screw sleeve integrally arranged with the expansion pipe, the inner hole diameter of the screw sleeve is not smaller than the outer diameter of the whole screw, and the transmission rod portion is composed of a connecting rod abutting against one end of the bolt head and a supporting shaft abutting against one end of the expansion rod portion. The maximum outer diameter of the screw sleeve is matched with the maximum outer diameter of the supporting shaft, abutting against one end of the expansion rod part, of the transmission rod part. According to the expansion bolt, the problem of the integrity of the bolt and the expansion pipe is solved, meanwhile, the integral arrangement of the expansion pipe and the screw sleeve improves the integral strength of the expansion bolt, and
