[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the role of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil is generally composed of base oil and additives. The base oil is the main component of the lubricating oil and determines the basic properties of the lubricating oil. The additive can make up for and improve the deficiencies in the performance of the base oil and give it some new properties. It is an important component of the lubricating oil.

[0037] When the second stirring blade 16 moves into the first stirring blade 15, the two scrapers 13 scrape off the lubricating oil on the surface of the second stirring blade 16 to prevent the second stirring blade 16 from bringing the lubricating oil into the first stirring blade 15 and filling the first stirring blade 15, thereby preventing the second stirring blade 16 from being unable to move into the first stirring blade 15 after being filled, thereby ensuring the normal operation of the mechanism.
