The utility model is made of main magnetite and the secondary magnetite of being located at active member and drive element respectively, utilizes the magnetic action of main magnetite and secondary magnetite, and the power source of active member is reached drive element, makes it obtain required power.

Described active member drives driving shaft by motor and rotates, and main magnetite is located on the active binding dish that driving shaft drives, and is the relative secondary magnetite of different poles with main magnetite and is located on the driven binding dish, and this driven binding dish is provided with the driven shaft of drive element.

Described active member drives driving shaft by motor and rotates, main magnetite is located on the active binding dish that driving shaft drives, being the relative secondary magnetite of homopolarity with main magnetite is located on the driven binding dish, this driven binding dish is provided with the driven shaft of drive element, and staggers in twos in the position of each main magnetite and secondary magnetite.

Described active binding dish, driven binding dish are to be provided with the corresponding position of card, and each main magnetite, secondary magnetite are located at initiatively binding dish, driven binding respectively and are coiled on the corresponding card.

Described active binding dish, driven binding dish are to be provided with the corresponding position of dish edge face, and each main magnetite, secondary magnetite are located on initiatively binding dish, driven binding respectively and coil on the corresponding dish edge face.

The planform of described driven binding dish is a umbrella.

The utility model utilizes the magnetic action of main magnetite and secondary magnetite, the power source of active member is passed to drive element, make it obtain required drive, so, can adjust the rotating ratio and the binding strength of driving shaft and driven shaft, because be that magnetic links,, also can adjust the torsion safety value so can isolate vibrating noise, solution Poewr transmission mechanism and the drift angle problem of power source.
