Magnetic stirrer

The utility model discloses a magnetic stirrer, which relates to the technical field of stirrers and comprises a bottom plate and a placing plate, the placing plate is U-shaped and is fixedly mounted on the upper surface of the bottom plate, and two strip-shaped openings are symmetrically formed in the top of the placing plate. A driving mechanism is arranged between the bottom plate and the placing plate, two connecting plates are in transmission connection through the driving mechanism, and the driving mechanism is matched with the two strip-shaped openings. According to the beaker, through the arrangement of the two magnetic blocks, due to the fact that the magnetic poles of the sides, close to each other, of the two magnetic blocks are the same, liquid in the beaker can be automatically stirred after the two magnetic blocks are placed on the two sides of the beaker, only the beaker needs to be cleaned after the beaker is used, and through the arrangement of the two arc-shaped clamping plates and the two s
