[0002] At present, in modern mechanical equipment, the drain screw plays a vital role. It is a key component for draining lubricating oil or coolant. However, in the use of traditional drain screws, some significant problems are easily encountered. First, when draining liquid, due to the wear caused by the operation of mechanical equipment, iron filings and other impurities may be mixed in the lubricating oil. These tiny impurities can easily clog the threaded part of the drain screw, resulting in the inability to completely drain the lubricating oil, thus affecting the normal operation of the equipment.

[0003] In addition, the existing drain screw structure design often ignores the effective collection of iron chips generated during the discharge process. These iron chips may be scattered inside and around the equipment during the discharge process, causing great inconvenience to the cleaning and maintenance of the equipment. The long-term accumulation of iron chips may also cause wear and tear on other parts of the equipment, reducing the service life of the equipment.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0008] Furthermore, in order to facilitate the rotation of the screw head, a plurality of grooves are provided vertically downward at the top of the screw head and outside the opening, and protrusions are provided on both sides of the screw head.

[0009] Furthermore, in order to facilitate the fixing of the screw, a limiting portion is provided at the top end of the spiral groove, and a limiting convex strip is provided on one side inside the limiting portion.

[0010] Furthermore, in order to facilitate the installation and placement of the sealing ring, a mounting groove matching the first sealing ring is provided on the outer side of the middle of the screw body.
