Embodiment

[0053] With reference to Figures 3-7The input part comprises a plurality of sets of liquid inlet holes 29, which are arranged on the end frame 31 and are used to communicate the injection cavity 21 and the built-in box 13. The liquid inlet holes 29 are communicated with the liquid cavity in the built-in box 13. A one-way valve 30 is arranged in the liquid inlet hole 29. The one-way valve 30 is communicated with the injection cavity 21. Therefore, the arrangement of the one-way valve 30 ensures that the cooling liquid in the liquid cavity can flow into the injection cavity 21 through the one-way valve 30 along the liquid inlet hole 29, so as to facilitate the timely supplement of the cooling liquid.

[0054] The injection cavity 21 is provided with a rotating disc 24. The penetrating rod 22 is coaxially rotated with the rotating disc 24. One end of the spiral belt 23 is fixed to the rotating disc 24. The other end of the spiral belt 23 is fixed to the outer side wall of the end of the penetrating rod 22 away from the rotating disc 24. The spiral belt 23 is abutted with the inner wall of the injection cavity 21. Since the penetrating rod 22 is stationary and the drill rod 9 is in a rotating state, the spiral belt 23 on the penetrating rod 22 rotates downward in a spiral direction relative to the injection cavity 21.

The inner diameter of the bottom groove 36 is greater than the inner diameter of the injection cavity 21. Therefore, when the metal disc 33 is pushed away from the injection cavity 21, the cooling liquid is sprayed out of the bottom groove 36 and reaches the drilling area, so as to complete the cooling, heat dissipation and debris removal operations.

[0057] The metal disc 33 blocks the injection cavity 21 through the elastic rope 35. The metal disc 33 has a gap with the bottom groove 36.
