The utility model discloses a quick switching magnetic pressure plate comprising a pressure plate and an installation seat. The installation seat is composed of fixation seats at the two ends and a connection plate in the middle. Each fixation seat is provided with a threaded rod. The upper ends of the two threaded rods are respectively provided with a nut and an end cap. One threaded rod is sleeved with the fixation end of the pressure plate through a bar hole and the fixation end of the pressure plate is arranged between the nut and the end cap of the threaded rod. The switching end of the pressure plate is clamped on the other threaded rod through a clamping slot and is arranged between the nut and the end cap of the threaded rod. An annular pressure pad is arranged between the switching end of the pressure plate and the end cap and another annular pressure pad is arranged between the switching end of the pressure plate and the nut. The quick switching magnetic pressure plate is capable of enabling the pressure plate to align accurately and switch quickly; besides, a certain magnetic force is formed between the two pressure pads up and down, so that the pressure pads are forced to be close to and in good contact with the pressure plate, the connection tightness of the pressure plate is improved, electric power safety accidents are prevented, work efficiency is improved, and maintenance cost is reduced.
