发明名称 Oil Filter Drain Tool
摘要 A fluid filter draining device is shown for draining fluid from a fluid container, such as an oil filter, in a controlled manner. An engagement ring is frictionally engaged on the outer sidewalls of a fluid filter. The engagement ring carries a threaded screw with a sharpened tip and a channel communicating between an opening at a forward end of the screw and a rear region of the threaded screw. When the screw is turned it penetrates the sidewall of the fluid container and enters the fluid containing cavity of the filter. Fluid is drained through the channel in the drill tip and out through an associated swivel hose connection and swivel hose to a collection container.
