Specific embodiment
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in Figures 1 to 4, the drive mechanism of a kind of permanent magnetic lifter rotating shaft that the utility model provides, including setting
In the handle of permanent magnetic lifter casing 1 sidepiece and fixed handle by block 2.The rotating shaft 3 of permanent magnetic lifter is worn from casing 1 sidepiece
Go out, handle includes one end fixing axle 4 connected with rotating shaft 3 sidepiece, is located in fixing axle 4 and can be relatively fixed axle 4 axially to be transported
Dynamic removable pin 5 and be set in sliding sleeve 6 in fixing axle 4, fixing axle 4 is perpendicular with rotating shaft 3, and the sidepiece of fixing axle 4 is along axle
To offering two symmetrical loose slots 7, sliding sleeve 6 and removable pin 5 are fixed even by the fixture 8 being located in this loose slot 7
Connect, therefore sliding sleeve 6 and removable pin 5 are axially moveable synchronization；The free end of fixing axle 4 is provided with a plug 9, this plug 9 with fixing
