Electromagnetic connecting device for biological tissue dewatering machine suspension arm and cylinder cover

The utility model relates to an electromagnetic connecting device for a suspension arm and a cylinder cover of a biological tissue dewatering machine. A cylinder cover (2) contains iron. The connecting device comprises an electromagnet (3) arranged on a suspension arm (1), and the electromagnet (3) is controlled by a control device (6). The electromagnetic connecting device for a suspension arm and a cylinder cover of a biological tissue dewatering (coloring) machine of the utility model can connect and separate the suspension arm and the cylinder cover conveniently, and can make the suspension arm alternately control two or more than two hanging baskets according to a set routine, which creates conditions for conducting the categorization and the batch processing of biological tissue simultaneously on one dewatering machine.
