The invention discloses a multi-combined automatic permanent magnet jack applicable to lifting and transporting of a complete steel plate. The automatic permanent magnet jack is characterized in that the dead weight of the jack is used as a power source, and a mechanical transmission device is used for performing transmission to enable a magnetic circuit in the jack to be closed according to different paths, so that the jack can enter an iron attracting state or an iron releasing state; all gears used in the mechanical transmission device are straight gears which can ensure the conversion precision; permanent magnets are fixed at the upper part and the lower part of a magnetizer shaft sleeve; the different magnetic poles of the upper permanent magnet and the lower permanent magnet are opposite to each other; the permanent magnets corresponding to the upper permanent magnet and the lower permanent are also fixedly arranged on a medium rotating shaft. According to the automatic permanent magnet jack, the jack automatically enters the iron attracting and releasing states through the reasonable design of the magnetic circuit and the mechanical transmission device, so that the problems of complex operation and small safety in plate lifting and transporting in a traditional process can be solved; the jack is safe and reliable in performance and convenient to use, can save a relatively large amount of manual operation, so that the labor intensity can be reduced.
