When the lubricating oil in the oil storage pipe 2008 is squeezed, the first sealing ball 702 and the inner wall of the first tapered tube 701 no longer abut against each other. At this time, the first one-way mechanism 7 is opened. When negative pressure is generated in the oil storage pipe 2008, the first sealing ball 702 and the inner wall of the first tapered tube 701 remain abutted against each other.

[0039] Working principle: When in use, when tapping the through hole 12 on the workpiece 11, the spiral groove tap body 1 is rotated and moved downward. At the same time, the rubber disc 15 is driven to move downward synchronously by the rotating rod 14, so that the rubber disc 15 is moved into the through hole 12. When the push rod 301 abuts against the surface of the workpiece, the moving disc 2009 is pushed to move upward. At the same time, the return spring 302 is compressed, so that the lubricating oil temporarily stored in the oil storage pipe 2008 can be squeezed. At the same time, the first one-way valve is closed and the first one-way mechanism 7 is opened. At this time, the lubricating oil in the oil storage pipe 2008 is squeezed and enters the lower cavity 2001 through the first hose 2010, and is sprayed out through the first connecting pipe 2011 and the oil supply pipe 16 through the oil spray hole 17;

[0040] When the return spring 302 cannot be further compressed, when the spiral groove tap body 1 continues to move downward, the first spring 203 is compressed, so that a certain amount of lubricating oil can be supplied between the spiral groove tap body 1 and the rubber disk 15, and under the blocking effect of the rubber disk 15, the leakage of the lubricating oil can be avoided, which not only ensures the lubrication effect, but also avoids the waste of lubricating oil, and is more energy-saving and environmentally friendly;

[0041] At the same time, when the first spring 203 is gradually compressed, the movable plate 404 moves upward in the oil storage tank 2014, and some air on the top of the oil storage tank 2014 can be discharged through the exhaust pipe 401. When the bottom of the oil storage tank 2014 abuts against the bottom of the L-shaped plate 502, the movable plate 404 stops moving, and at the same time, the second spring 603 is gradually compressed.

[0042] After the drilling is completed, the spiral groove tap body 1 is moved upward, and the rubber disc 15 is driven to move upward by the rotating rod 14. At this time, the first spring 203 is gradually reset, so that the moving plate 404 moves downward in the oil storage tank 2014, so that negative pressure is generated in the oil storage tank 2014. At the same time, the second one-way valve is closed, and the second one-way mechanism 9 is opened. At this time, the lubricating oil remaining between the spiral groove tap body 1 and the rubber disc 15 can be absorbed through the oil extraction hole 19, and enter the upper cavity 2002 through the oil extraction pipe 18 and the second connecting pipe 403, and then enter the oil storage tank 2014 through the third hose 402;

[0043] When the push rod 301 is separated from the surface of the workpiece, the movable plate 2009 can move downward and reset under the action of the reset spring 302, so that the oil storage pipe 2008 is reset. At the same time, the first one-way valve is opened and the first one-way mechanism 7 is closed. At this time, the lubricating oil in the oil storage tank 2014 can enter the oil storage pipe 2008 through the second hose 2013, and so on. After the tapping is completed, the residual lubricating oil can be recycled and reused, avoiding the waste of lubricating oil and being more energy-saving and environmentally friendly.
