A perfusion repairing area corresponding to the crack/seam and glue applying areas for applying glue are arranged on the bottom surface of the sticky pad, and the glue applying areas are on the outer sides of the perfusion repairing area. The injector is provided with a needle. The invention can forcibly perfuse the repairing liquid into the crack/seam by external force in the vacuum state, so 0 as to ensure the sufficient and uniform perfusion of repairing liquid without blind space, it even isolates the contact of the glued space with the outside to realize the genuine dust-free operation, thus it solves the long-existing universal difficulty that the crack/seam on surface of object can't be fully and seamlessly repaired.3/5 121 120 124/ 123 Figure 5 124 120 122 Figure 6
