Aluminum veneer recess repairing device and using method

The invention belongs to the technical field of building construction, and particularly relates to an aluminum veneer recess repairing device which comprises a suction cup, a pipeline providing adsorption force for the suction cup and an adjusting assembly used for changing the position of the suction cup, and the pipeline is driven to enable the suction cup to tightly suck the recess position of an aluminum veneer. The device has the beneficial effects that the adjusting assembly is arranged on the suction cup, the position of the suction cup can be adjusted so that the suction cup can be aligned with a sunken part for repairing, the device can be stably supported by means of other structures, the device can adapt to the sunken parts at different positions, manual climbing or adopting of large auxiliary tools such as a hanging basket is not needed any more, the repairing efficiency is improved, and the labor intensity of workers is relieved. Cost is saved, and practicability is higher; through cooperative us
