Magnetic coupling with forward and reverse rotation function

The utility model discloses a magnetic coupling with forward and reverse rotation functions. The magnetic coupling comprises a magnetic coupling joint A, an electric spindle output end, a rubber pad and a magnetic coupling joint B, a joint A of the magnetic coupling is mounted at the output end of the motorized spindle according to a 3 # Morse taper fit mode; the rubber pad is mounted between the magnetic coupling A joint and the magnetic coupling B joint to prevent rigid contact between the two joints; and one end of the magnetic coupling B joint is tightly attracted with the magnetic coupling A joint by magnetic force and is separated by a rubber pad, and the other end of the magnetic coupling B joint is connected with a driven shaft. The device is stable in operation under a test condition, can effectively eliminate the installation deviation of the driving end and the driven shaft of the motorized spindle, has positive and negative rotation functions in a 3 # Morse taper matching mode, and is suitable for
