[0020] Specifically, there are four chip removal holes 14. The chip removal holes 14 facilitate the discharge of waste chips from the chip removal holes 14. The hole opener 3 is fixed to the outside of the first boss 15 by threads.

[0021] The bottom of the first protrusion 15 is connected to a positioning drill 4. The positioning drill 4 is an integral structure, mainly composed of a main body 8, a mounting part 5 and a positioning post 6. The upper end of the main body 8 is provided with a positioning post 6. The connecting seat 2 is provided with a positioning hole 17 corresponding to the positioning post 6. The mounting part 5 is provided at the intersection of the positioning post 6 and the main body 8. The main body 8 is connected to the connecting seat 2 through the mounting part 5.

[0022] Specifically, the positioning pin 6 engages with the positioning hole 17 at the bottom of the connecting seat 2, thereby inserting the positioning drill 4 into the bottom of the connecting seat 2, and the mounting part 5 engages with the external thread of the second boss 16 to fix the positioning drill 4 to the bottom of the connecting seat 2.

[0023] Furthermore, the mounting part 5 is mainly composed of an annular plate and a mounting nut 7. An annular plate is provided at the intersection of the main body 8 and the positioning post 6. The outer side of the annular plate is fixed to the second boss 16 on the connecting seat 2 by the mounting nut 7.

[0024] Furthermore, the mounting nut 7 has a groove in the middle to accommodate the annular plate, and a hole at the bottom of the groove to facilitate the passage of the main body 8.

[0025] Specifically, the hole at the bottom of the mounting nut 7 groove is larger than the outer diameter of the main body 8 but smaller than the outer diameter of the annular plate, and the groove wall of the mounting nut 7 is provided with internal threads.

[0026] Furthermore, the positioning post 6 is a polygonal column, and the shape of the positioning hole 17 is consistent with the shape of the positioning post 6.

[0027] Specifically, the positioning post 6 is a rectangular post, and the positioning hole 17 is also rectangular. Through the cooperation between the positioning hole 17 and the positioning post 6, the tool holder 1 and the connecting seat 2 can drive the positioning drill 4 to rotate, thereby drilling and positioning the plate.
