[0028] People pull the handle 75 upwards, and the handle 75 drives the rotating plate 74 to swing upwards. Then, the water storage frame 73 is filled with clean water, and the handle 75 is released. The rotating plate 74 swings downward due to gravity to reset. Then, the rolled steel is placed between the first guide wheel 55 and the second guide wheel 56, and the first motor 52, the dust collection unit 67, the hair dryer 96 and the second motor 102 are started.
