An assembly structure of a tubular body and a handle includes a tube, two connecting members, a handle, a position-limiting member and a blocking member. The tubular body has at least one pair of insertion holes. Each connecting member has a concave surface with a positioning post. The connecting members are mounted on the outer periphery of the tubular body with the positioning posts inserted into the insertion holes respectively. The handle is connected to a coupling base. The coupling base has a mounting hole and is mounted around the connecting members. The position-limiting member and the blocking member are provided at two opposite ends of the connecting members respectively and abut against two opposite ends of the coupling base respectively. The assembly structure allows the handle to be easily and securely mounted and positioned on the tubular body.
