Assembly structure of tubular body and handle

An assembly structure of a tubular body and a handle, comprising:

• a tubular body, which has an outer peripheral wall with two sides each provided with at least one insertion hole;
• two connecting members each having a wall surface curved inward to form a concave surface, the concave surface of each of the two connecting members is protrudingly provided with a positioning post, the two concave surfaces of the two connecting members are mounted on the outer periphery of the tubular body, the two positioning posts are inserted into the two insertion holes of the tubular body respectively, and each of the two connecting members has two ends defined respective as a first end and a second end;
• a handle, which is connected to a coupling base, the coupling base has a first end and a second end;
• a mounting hole is provided in and passes through the coupling base and opens at the first end and the second end of the coupling base, the coupling base is mounted around the two connecting members, and the two connecting members are restricted in the mounting hole;
• a position-limiting member formed as a hollow cylinder, the position-limiting member has a through hole extending along an axial direction of the position-limiting member, and the position-limiting member is connected to the first ends of the two connecting members and abuts against the first end of the coupling base;
• and
• a blocking member provided at the second ends of the two connecting members, the blocking member abuts against the second end of the coupling base.
