The mounting plate 4 has a spherical concave surface concentrically arranged with the swirling ball 3, and the spherical concave surface is spaced apart from the outer wall of the swirling ball 3. Thus, when the vortex ball 3 rotates, the distance between the mounting plate 4 and the vortex ball 3 is the difference between the outer diameter of the vortex ball 3 and the inner diameter of the mounting plate 4, and is kept constant. The mounting plates 4 are made of iron and no contact can be made between the two mounting plates 4. In this embodiment, the two spherical center concavities are on the same spherical surface, but in some embodiments, the two concavities may not be on the same spherical surface.

Wherein each set of magnets 5 is attached to the corresponding spherical concave surface of the mounting plate 4, while in other embodiments, each set of magnets 5 may be embedded in the corresponding mounting plate 4 such that the first spherical surface coincides with the spherical concave surface.
The number of the second linkage shafts 6 is at least one, the specific number of the second linkage shafts is the same as that of the driven parts, and in the embodiment, the number of the second linkage shafts 6 is two. Each linkage shaft II 6 is fixedly connected to the corresponding mounting disc 4, and the central shaft penetrates through the spherical center of the vortex ball 3 and the surrounding center of the corresponding group of magnets 5. The two linkage shafts II 6 are symmetrical about the central axis of the linkage shaft I1, and the included angle of the central axes of the two linkage shafts II 6 is larger than 90 degrees and smaller than 180 degrees. The second linkage shaft 6 can be used as a driven shaft and can also be directly or indirectly connected with an external driven shaft. The structure and the shape of the linkage shaft II 6 are similar to those of the linkage shaft I1, and the linkage shaft II comprises a circular truncated cone II and a cylinder II. The second cylinder and the second circular truncated cone are coaxially arranged and fixedly connected, and can be integrally formed.

Like this, universal driving shaft 1 just can drive one or more universal driving shaft two 6 and rotate to do not have direct contact between initiative and the driven part, do not have friction and mechanical wear, reduce the resistance and improve power transmission efficiency on the one hand, on the other hand reduces wearing and tearing, improves the life of structure, still possesses the protect function simultaneously, when the moment of torsion is too big or the rotational speed sudden change is too big, can play the effect that buffering or transmission stopped.
