Compared with the prior art, the utility model has the advantages that:

1. fix filter paper inside the metal filter screen, rethread filter paper fine filtration after tentatively filtering through the metal filter screen can effectively filter machine oil to large granule impurity is blockked by the metal filter screen and can not adhere on filter paper.

2. Through set up the metal filter screen at filter paper periphery side, can effectively disperse machine oil, further avoid filter paper to be washd out the deformation.

3. In the engine use, the engine produces vibrations, takes the vibrations of engine oil filter, offsets some vibrations through setting up spacing spring, can realize that limiting plate and metal filter screen take place relative displacement, and the scraper blade is scraped on metal filter screen surface promptly, will be attached to the large granule impurity on metal filter screen surface and scrape, and large granule impurity subsides the shell bottom with the metal filter screen separation back, avoids impurity cover to influence the filter effect on metal filter screen surface.
