The second friction disk 19 can drive the first friction disk 18, the third connecting shaft 17 and the second fixing plate 22 to rotate through friction force. The second fixing plate 22 drives the first fixing plate 20 and the lifting column 8 to rotate synchronously through the guide post 21. While the lifting column 8 rotates, the inner wall of the spiral groove 9 slides relative to the end of the support column 10, so that the lifting column 8 and the three-jaw chuck 3 move downward synchronously. When the first fixing plate 20 and the lifting column 8 descend to the lowest position, the bottom of the first fixing plate 20 contacts the top of the second fixing plate 22. The first fixing plate 20 and the lifting column 8 cannot move downward, and the inner wall of the spiral groove 9 cannot slide relative to the end of the support column 10. With the continuous rotation of the second friction disk 19, the second friction disk 19 cannot drive the first friction disk 18 to rotate synchronously through friction force, so that the three-jaw chuck 3 and the cross drill 4 can automatically stop after descending to the preset position without additionally arranging an automatic control unit;

[0041] When it is necessary to drive the cross drill bit 4 and the three-jaw chuck 3 to reset to the initial height, the first connecting shaft 5 and the rotating shell 6 are driven to translate through the self-rotation translation structure, and the polishing roller 7 is no longer in contact with the cross drill bit 4, so that the polishing roller 7 no longer interferes with the upward movement of the cross drill bit 4.

The bottom end of the positioning column 29 is inserted into the corresponding positioning hole 32, which can limit the position of the movable seat 25 and the support column 10 at this time. The support column 10 no longer interferes with the upward movement of the lifting column 8. The staff drives the three-jaw chuck 3 and the cross drill bit 4 to move upward, and the first fixed plate 20 moves upward relative to the second fixed plate 22 and the guide column 21. The three-jaw chuck 3 and the cross drill bit 4 move up to At the initial height, the staff drives the baffle 34 to slide relative to the guide frame 35 and the operating table 1 through the handle 38, and the iron plate 36 is no longer magnetically attracted to the corresponding magnet block 37. The end of the baffle 34 moves to the bottom of the first fixed plate 20, and the top of the baffle 34 contacts the bottom of the first fixed plate 20, and the iron plate 36 is magnetically attracted to another corresponding magnet block 37. At this time, the baffle 34 supports the first fixed plate 20. Similarly, the staff drives the movable seat 25 to translate in the opposite direction to the initial position again, and the end of the support column 10 is inserted into the spiral groove 9 again. The staff can release the clamping and fixing of the cross drill bit 4 through the three-jaw chuck 3, and drive the bolt 24 to rotate to make the bolt 24 disengage from the three-jaw chuck 3 and the mounting plate 23, so as to complete the separation between the three-jaw chuck 3 and the lifting column 8. The staff drives the lifting column 8 to move upward to make the first fixed plate 20 disengage from the guide column 21, and the lifting column 8 is dismantled, which is convenient for replacing the lifting column 8 and the three-jaw chuck 3, and then facilitating the polishing of the cross drill bits 4 of different specifications.

The toothed plate 54 can drive the rotating shell 6 to rotate relative to the first connecting shaft 5 through the arc-shaped rack 55, thereby changing the inclination angle of the polishing roller 7. When it is necessary to drive the polishing roller 7 and the first connecting shaft 5 to move horizontally so that the polishing roller 7 does not interfere with the bottom end of the cross drill bit 4 inserted into the three-jaw chuck 3, the staff drives the stop plate 49 to rotate relative to the rotating shell 6 so that the horizontal position of the bottom of the stop plate 49 is higher than the top horizontal position of the support plate 51. The staff drives the stop plate 49, the rotating shell 6 and the arc-shaped rack 55 to translate relative to the toothed plate 54. The first connecting shaft 5 slides relative to the slider 47, and the second tension spring 48 is in a stretched state. When the polishing roller 7 is translated horizontally to the preset position, the staff drives the stop plate 49 to rotate in the reverse direction. The stop plate 49 rotates to the side of the support plate 51 away from the rotating shell 6, and the stop plate 49 and the support plate 51 are in contact with each other, so that the rotating shell 6 and the polishing roller 7 can be kept stationary in the horizontal direction. When it is necessary to drive the polishing roller 7 to move horizontally in the reverse direction so that the polishing roller 7 contacts the drill groove on the cross drill bit 4, similarly, the staff drives the stop plate 49 to rotate so that the stop plate 49 no longer contacts the support plate 51. The rotating shell 6 and the polishing roller 7 move horizontally in the reverse direction. The polishing roller 7 abuts against the drill groove of the cross drill bit 4, and the second tension spring 48 is in a stretched state.

The second rotating shaft 42 drives the fourth connecting shaft 44 and the slider 47 to rotate through the first bevel gear 43 and the second bevel gear 45. The slider 47 can drive the first connecting shaft 5 and the third bevel gear 56 to rotate. The third bevel gear 56 drives the polishing roller 7 to rotate through the fourth bevel gear 57.
