When tapping the blind hole, after the ball 21 abuts against the bottom of the blind hole, when the extrusion tap body 1 continues to move upward, the air inlet pipe 20 moves upward along the top of the U-shaped plate 901. At the same time, the third spring 903 is compressed, so that when exhausting air, external air can enter through the air inlet pipe 20 and enter the bottom of the blind hole through the air hole 22.

The filtered air enters the fixed cover 301 through the connecting pipe 19 for temporary storage, thereby facilitating the collection of debris and making it more convenient and quick to use.
[0037] Working principle: When in use, when tapping a through hole, the extrusion tap body 1 is rotated and moved downward, and at the same time, the fixing ring 11 and the annular plate 13 are driven to move downward, and then the annular cover 14 is driven to move downward. When the annular cover 14 abuts against the surface of the workpiece, the first spring 203 is gradually compressed, and at the same time, the telescopic cover 15 is gradually compressed;
[0038] When the fixed ring 11 moves downward, the rack 702 is driven to move downward through the connecting plate 801 and the connecting rod 802, so that the gear 701 and the rotating shaft 602 rotate clockwise, thereby driving the winding roller 501 to rotate, and the pull rope 502 can be reeled in, thereby pulling the movable plate 302 to move away from the fixed cover 301. At the same time, the second spring 404 is compressed, and the first one-way valve is opened and the second one-way valve is closed. At this time, the air can be pumped through the first circular hole 16. After the air in the telescopic cover 15 is completely pumped out, the air can be pumped from the bottom of the through hole, so that the air flows from bottom to top, thereby driving the debris to be discharged upward, thereby facilitating the chip removal.
[0039] Furthermore, when tapping the blind hole, after the ball 21 abuts against the bottom of the blind hole, when the extrusion tap body 1 continues to move upward, the air inlet pipe 20 moves upward along the top of the U-shaped plate 901, and at the same time, the third spring 903 is compressed, so that when exhausting air, external air can enter through the air inlet pipe 20 and enter the bottom of the blind hole through the air hole 22. At this time, the air can also flow from bottom to top, thereby driving the debris to be discharged upward, so as to facilitate the chip removal, and the applicability is stronger and the use effect is better;
[0040] The debris is absorbed through the first circular hole 16 and then enters the collection box 18 through the exhaust pipe 17 for filtration. Under the action of the filter screen 1004, it is filtered and collected in the filter box 1001. The filtered air enters the fixed cover 301 through the connecting pipe 19 for temporary storage, so that the debris can be collected easily and the use is more convenient and quick.
[0041] After the drilling is completed, when the extrusion tap body 1 moves upward, the movable plate 302 can move and reset under the action of the second spring 404, so that the air temporarily stored in the fixed cover 301 can be squeezed. At the same time, the first one-way valve is closed and the second one-way valve is opened. At this time, the air in the fixed cover 301 is squeezed and enters the annular cover 14 through the air outlet pipe 303 and blows onto the working part 102 through the first circular hole 16, so that the debris remaining on the surface of the working part 102 can be blown clean, and the cleaning is more convenient and quick, and the effect of subsequent tapping is guaranteed.
