The invention discloses a pull rod connecting structure for the balance arm of a tower crane. The pull rod connecting structure comprises two pull rods (1) which are equal in length and arranged side by side, a transitional set square component (5) and a pulling plate component (3), wherein the bottom ends of the two pull rods (1) are connected with a balance arm, the top ends of the two pull rods (1) are respectively connected with two horizontal holes in the bottom of the transitional set square component (5) in a symmetrical and adjustable manner; the top of the pulling plate component (3) is connected with a tower top (2), an inverted set square (7) is arranged at the bottom of the pulling plate component (3), a single orifice in the top of the transitional set square component (5) is connected with a single orifice in the bottom of the inverted set square (7). The movable type transitional set square component in the middle meet the requirements of load balance of the two pull rods, and the complete machine stability is improved; two bending plate components in an original pulling plate component are changed, the processing technique is lowered, the production efficiency is improved, and the cost is reduced.
