for iron workpieces: the magnet exciting coil 3 is charged, the magnet exciting coil 3 works to obtain electric excitation, and magnetic lines of force pass through the sucker shell 2 and the sucker panel 1 to penetrate through a workpiece to form a complete magnetic loop to suck the iron workpiece. After the holding is finished, the excitation coil 3 is powered off, the external magnetic force lines disappear, and the workpiece can be easily taken away. For workpieces such as high carbon steel and the like which are not easy to demagnetize, the forward and reverse ventilation mechanisms 4 work to inflate the sucker panel 1, so that the workpieces can be supported in an auxiliary manner and can be taken away easily.
