The invention provides a sliding edge screw dismounting tool. The sliding edge screw dismounting tool comprises an inner cutter bar, an outer cutter bar, a screw fixator and a torsion sensing system. The screw fixer comprises a main force gear disc, a grooved chassis and a gear tool bit; a spiral bulge is arranged on the bottom surface of the main force gear disc; the bottom disc with the groove is tightly attached to the bottom surface of the main force gear disc; the gear tool bit is of an arch-shaped structure with one sharp end, grooves are formed in the outer wall of the arched side of the gear tool bit at intervals, and the grooves are meshed with the spiral protrusions. The main force gear disc is rotated to drive the gear tool bits to move in the direction of the center of the base plate with the groove through threads, the tip ends of the gear tool bits are finally inserted into one side of a nut, the multiple gear tool bits act at the same time, the nut is firmly clamped, the torsion for disassembli
