The invention discloses a torque connecting structure. The torque connecting structure is composed of a connecting disc, force rods, bushings and locking screws, a plurality of circumferential mounting holes are formed in the connecting disc, axial mounting holes communicated with the circumferential mounting holes are formed in the circumferential mounting holes, rectangular grooves are formed inthe force rods, the force rods are partially mounted in the circumferential mounting holes, the bushings are mounted in the circumferential mounting holes, and the locking screws penetrates through the axial mounting holes and are inserted into the rectangular grooves. The torque connecting structure is combined with the corresponding 7/T/+-shaped wrench, a booster sleeve is used, the detaching and installation space is small, the dead angle screw of a wrench arm force cannot be directly lengthened, and the torque connecting structure has the advantages of being high in bearing capacity, lowin processing cost, high in reliability and compact in structure and the like.
