[0031] Referring to Figure 3 - Figure 4, The dispersion mechanism includes a connector 20 which plays a role in connecting and rotating. The connector 20 is fixedly connected to the bottom end of the rotating shaft 7. An fixing plate 19 is rotatably connected to the outside of the connector 20 which plays a connecting role.
