Flexible ultra-thin glass cutting device convenient to position

The utility model discloses a flexible ultra-thin glass cutting device convenient to position, which belongs to the technical field of flexible glass and comprises a fixing box, fixing legs are fixed on the periphery of the bottom of the fixing box, through holes are formed in the periphery of the top of the fixing box, inner cavities of the through holes are movably connected with pistons, and the pistons are movably connected with the fixing legs. The flexible glass is adsorbed to the top of the fixing box through cooperation of the through hole and the piston and by means of the air pressure difference, the stability of the flexible glass is guaranteed, meanwhile, a gas positioning mode is adopted, a traditional rigid contact positioning mode is avoided, the mode of utilizing the gas pressure intensity is gentle, and the flexible glass is not prone to falling off. And the flexible glass is prevented from being cut. And meanwhile, through cooperation of the limiting mechanism, the flexible glass is convenie
