The utility model discloses a clamping structure with an upper clamping plate and a lower clamping plate for a printing plate clamping device, which comprises an upper clamping plate, a lower clamping plate and a printing plate. When the inner side of the upper clamping plate is under action of a clamping mechanism, the lower end face of the outer side of the upper clamping plate and the upper end face of the lower clamping plate fixed on a roller form a clamping surface to clamp and loosen the printing plate, the lower end face of the outer side of the upper clamping plate adopts a plane, the upper end face of the lower clamping plate adopts an inner curved surface, and when the upper clamping plate is unfolded, the highest point of the arc of the upper end face of the lower clamping plate and the root part of the upper clamping plate form a clearance with the width more than the thickness of the printing plate. The utility model can fix the printing plate more stably and improve the efficiency of clamping f
