[0002] When a mechanical mechanism or device is working, in order to reduce the friction generated and reduce the loss between parts, lubricating oil is usually used to lubricate the parts to achieve the purpose of reducing friction. If there are impurities in the lubricating oil, the lubrication effect will be affected. Therefore, the impurities must be removed. However, existing devices have certain problems when used and still need to be continuously improved.

[0003] For example, the utility model with authorization announcement number CN220715023U discloses a lubricating oil filter for removing impurities in lubricating oil. The device includes a frame and an upper barrel body with a protective function arranged on the frame. The frame cooperates with the placement surface. The liquid inlet dispersion device is used for the lubricating oil to enter the interior of the upper barrel body and disperse the lubricating oil to the inner wall of the upper barrel body after the lubricating oil enters the interior of the upper barrel body. The filtering device filters the lubricating oil dispersed to the inner wall of the upper barrel body to remove impurities in the lubricating oil. The liquid discharge device is used to discharge the lubricating oil filtered by the filtering device. Through the cooperation of the opening, the liquid inlet pipe, the closing plate, and several dispersion pipes, the lubricating oil enters the interior of the upper barrel body and disperses the lubricating oil to the inner wall of the upper barrel body after the lubricating oil enters the interior of the upper barrel body. The incoming lubricating oil can be dispersed first and then filtered, and the effect of removing impurities in the lubricating oil is better.

[0004] When the device is in use, the lower barrel body is fixedly installed under the upper barrel body by means of bolts. However, each time the primary filter and the final filter in the lower barrel body are disassembled and cleaned, it is necessary to use external tools to remove the multiple bolts that limit and fix the upper and lower barrel bodies, which causes certain inconveniences.
