[0002] The car sheet metal suction cup is a tool specially designed for car sheet metal repair work. It uses the difference in atmospheric pressure inside and outside to repair the sunken parts of the car sheet metal by adsorbing on the object. This tool is widely used in the car repair industry. It can play a good repair effect on the sunken problems of car doors, engine hoods and other parts. In the process of car repair, the sheet metal suction cup is a common tool.
