As shown in FIG. 1 to FIG. 4 , the present invention provides a magnetic drive device including a rotating shaft 10 , a transmission mechanism 20 , a first magnetic mechanism 30 , a second magnetic mechanism 40 and a magnetic isolation mechanism 50 .

The rotating shaft 10 is rotatably arranged around its central axis, one end of the transmission mechanism 20 is connected with the rotating shaft 10, and the other end is connected with the first magnetic mechanism 30. When the rotating shaft 10 rotates, the first magnetic mechanism 30 is driven to move by the transmission mechanism 20 .

That is, when the first magnetic mechanism 30 moves close to or away from the rotating shaft 10 , correspondingly, the first magnetic mechanism 30 also moves close to or away from the second magnetic mechanism 40 . The opposite ends of the first magnetic mechanism 30 and the second magnetic mechanism 40 have the same polarity, that is, the second magnetic mechanism 40 can apply a pushing force to the first magnetic mechanism 30 . According to the principle of like-pole repulsion, a repulsion force is formed between the second magnetic mechanism 40 and the opposite ends of the first magnetic mechanism 30 , so that the second magnetic mechanism 40 can push the first magnetic mechanism 30 toward the rotation shaft 10 .

The magnetic isolation mechanism 50 includes a magnetic isolation sheet 51 arranged to move, and the moving direction is arranged at an angle with the moving direction of the first magnetic mechanism 30 . During the moving process, the magnetic isolation sheet 51 can move between the first magnetic mechanism 30 and the second magnetic mechanism 40 .

The second magnetic mechanism 40 prevents the second magnetic mechanism 40 from affecting the movement of the first magnetic mechanism 30 .

When the first magnetic mechanism 30 moves to the limit of its travel away from the rotating shaft 10 , the first magnetic mechanism 30 will then move away from the second magnetic mechanism 40 . At this time, the magnetic isolation sheet 51 is moved to the first magnetic mechanism 30 and the second magnetic mechanism 40 . On the side of the second magnetic mechanism 40 , the second magnetic mechanism 40 pushes the first magnetic mechanism 30 , thereby driving the rotating shaft 10 to rotate, increasing the rotational speed and torque of the rotating shaft 10 , so that the rotating shaft 10 can drive heavier mechanical equipment.
