Preservation machine based on magnetic sterilizing technology

The invention provides a preservation machine based on the magnetic sterilizing technology, and relates to the technical field of preservation cabinets. Springs are fixedly mounted in grooves, and sliding blocks are fixedly mounted at the ends, away from the grooves, of the springs. Inserting rods are fixedly mounted at the ends, away from the springs, of the sliding blocks, and strip-shaped plates are fixedly mounted on the two sides of the grooves. Sliding grooves are formed in the surfaces of the strip-shaped plates, and a U-shaped plate is slidably connected in the sliding grooves. According to the preservation machine, due to the fact that an auxiliary device is arranged, when impounded water needs to be drained out of a cabinet body, the inserting rods are separated from inserting holes, and consequently a sealing plug and the cabinet body fail to be fixed; and the sealing plug is pulled out of the cabinet body at this moment, the impounded water at the bottom of the cabinet bodyflows out of the cabinet
