The invention provides a lower wall plate shape-preserving positioning tool which is composed of a main body large frame, a front trapezoidal supporting frame, a rear trapezoidal supporting frame, a triangular bracket, a lower wall plate shape-preserving adsorption assembly, a lower wall plate net edge positioning assembly, clamping plate manual jacking mechanisms, a TB standard block, a rotary hanging ring, a positioning cup cone assembly and the like. The triangular bracket is mounted on the triangular bracket connecting plate of the front trapezoidal supporting frame. Eight sets of clampingplate manual jacking mechanisms are arranged, each set of clamping plate manual jacking mechanism is composed of a lead screw shaft, a guide sleeve, a limiting nail, a bearing mounting sleeve, a driving nut, a ball bearing, a handle and a sealing cover, and the lower wall plate shape-preserving adsorption assembly comprises four arc-shaped large clamping plates, eight adjusting fork lugs, a vacuum suction cup and a vacuum adsorption air source device. The lower wall plate net edge positioning assembly is composed of a short side edge positioning block assembly and a long side edge positioningblock assembly. The lower wall plate shape-preserving positioning tool is simple in structure and ideal in manufacturing manufacturability and assembling manufacturability.
