[0021] Furthermore, the side of the drill bit 2 is provided with evenly distributed guide holes 21. When high-pressure air is discharged from a part of the drill bit 2, the air pressure in that part increases. At the same time, the drill bit 2 with the guide holes 21 can move the crushed rock powder away from the drill bit 2, thereby moving the rock powder to the outside of the drill hole and moving it into the telescopic sleeve 4.

[0022] Furthermore, the driver includes a motor 7 installed at the fixed end of the telescopic sleeve 4, a main pulley 71 is provided on the output shaft of the motor 7, and a secondary pulley 6 is provided at the position of the drill rod 1 corresponding to the main pulley 71, a belt 72 connected to the secondary pulley 6 is sleeved on the main pulley 71, the motor 7 drives the main pulley 71 to rotate, the main pulley 71 drives the secondary pulley 6 to rotate through the belt 72, and the secondary pulley 6 drives the drill bit 2 to rotate through the drill rod 1.
