The invention relates to an inserting type modular steel structure connecting joint with a reset function. The inserting type modular steel structure connecting joint comprises a modular steel structure connecting joint body and self-reset haunch supports, wherein the modular steel structure connecting joint body comprises two upper module units, two lower module units, a cross-shaped inserting pin connecting piece, a vertical cover plate, a horizontal cover plate and high-strength bolts, and the four self-reset haunch supports internally provided with disc springs are symmetrically arranged at the corner parts of the joint body and are hinged to module beam columns. According to the inserting type modular steel structure connecting joint, module units are connected through the cross-shaped inserting pin connecting piece, the cover plate and the high-strength bolts, so that it is guaranteed that the joint has enough tensile strength, shear strength and bending strength, a connecting device has no need occupying the use space of a building, the application range is wide, and meanwhile attractiveness is guaranteed; and the arrangement of the self-reset haunch supports can improve thebearing capacity of the joint, delay degradation of the rigidity and strength of the joint, reduce damage to the joint beam-column intersection, avoid premature damage to components, achieve rapid repair and guarantee stability and reliability of the joint performance, and residual deformation after an earthquake is small.
