plate 403 and the rotating block 406 to rotationally slide on the outer wall of the scraping sleeve 401, thereby make and dial board 403 and stir rotation in lubricating oil, carry out the stirring in another position to lubricating oil, then the omnidirectional is dialled to lubricating oil and is dispersed the mixture, and along with scraping set 401 and descend, slider 404 slides to the top of little spout, along with scraping set 401 and descend and finish, slider 404 is scraped set 401 then along with being scraped the inertia that set 401 promoted the decline and slide once more in the twinkling of an eye this moment and descend, will dial board 403 once more pushback through the pulling of elastic strip B405, realize once more the vibrations to dialling board 403 outer wall, thereby carry out abundant mixture to lubricating oil, promote the lubricated effect of lubricating oil, electricity generation and transmission efficiency have been guaranteed.
