A floating rotor is disposed inside the housing, and a floating figure-eight ring drive component is disposed on one side of the housing. The rotor and the figure-eight ring drive component are connected in a driving connection. A drive shaft is inserted into the middle of the rotor. The rotation of the drive shaft causes the rotor to float inside the housing. A support shaft is disposed on one side of the inside of the housing, and the figure-eight ring drive component is fixedly mounted on the support shaft. A locking component is disposed on the top of the support shaft.

[0006] In a preferred embodiment of this utility model, both the upper cover and the bottom cover are fixedly connected to the outer shell by connecting bolts, and bolt holes are provided at the top and bottom of the outer shell, with the connecting bolts fixed inside the bolt holes.
