Preferably, as shown in fig. 1, the first rotating block 2 is provided with a slot 21 penetrating vertically, and the rotating magnet 1 is located in the slot 21 so that the rotating magnet 1 is restricted from rotating relative to the rotating module by the slot 21. Of course, the first rotating block 2 may be provided with another structure capable of restricting the rotation of the rotating magnet 1, for example, a stopper may be provided to restrict the rotation of the rotating magnet 1.

In this embodiment, the first rotating block 2 and the second rotating block 3 are arranged to fix the rotating magnet 1, so that the rotating magnet 1 can be directly placed in the slot 21 of the first rotating block 2 without using gluing or other methods requiring connection, thereby facilitating the replacement of the rotating magnet 1. Furthermore, the rotary magnet 1 can be prevented from being attracted by the upper magnetic workpiece 12 and being separated from the rotary module by the attraction of the second rotary block 3. Of course, the technical solution provided by the present invention does not exclude the way that the rotating magnet 1 is fixed on the rotating module or directly fixed on the motor shaft.
