[0023] The power assembly includes an electric push rod 3, which is fixed to the top outer wall of the shell 1 by bolts. One end of the telescopic portion of the electric push rod 3 passes through the shell 1 and is fixed with a disc 16 by bolts. The circumferential outer wall of the disc 16 is fixed with multiple connecting plates 12 by bolts, wherein one side of two connecting plates 12 is welded with a fixing plate 14, and the fixing plate 14 is fixed to the telescopic portion of the telescopic tube 15. The electric push rod 3 pushes the disc 16 to move downward, and the disc 16 drives the connecting plate 12 to move downward. The connecting plate 12 will drive the fixing plate 14 to move downward, and the fixing plate 14 will stretch the telescopic tube 15, thereby extending the telescopic tube 15.

[0024] In the utility model, in order to prevent the waste oil and waste water from adhering to the inner wall of the shell 1, a scraper 13 is welded at one end of a plurality of connecting plates 12, so that the inner wall of the shell 1 is cleaned. The connecting plates 12 will drive the scraper 13 to move during the movement, so that the scraper 13 scrapes and cleans the inner wall of the shell 1.
