Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Include a mounting disc sheet referring to Figures 1 and 2 it is found that the utility model provides a kind of convex permanent magnet mounting disc 5
Body 51 is fitted around disk body central on 51 side side of the mounting disc ontology and is uniformly fixed with several convex shells 52,
It is corresponded on 51 other side side of the mounting disc ontology and offers one respectively at the position of each convex shell 52 and extend to convex shell
52 inside of body and mounting groove 53 corresponding with permanent magnet 6, moreover, the quantity of mounting groove 53 is even on the mounting disc ontology 51
Number.
