In this way, when the drill bit 2 drills the tunnel lining, the dust and debris generated will be blown to the storage box 4 by the suction force of the air suction fan 6 and then accumulated on the filter screen 8. After drilling is completed, the filter screen 8 is taken out of the storage box 4 to clean the dust and impurities thereon. This avoids the dust and impurities generated during drilling from floating in the air, which harms the health of workers and the environment, further ensuring the health of workers and environmental safety. The drill bit 2 is conveniently replaced by installing the clamping groove 19. When the drill bit 2 is installed, first, the nut 21 is rotated to the bottom end of the clamping groove 19 (the top end of the clamping groove 19 is separated by the gap 20, and the two separated ends expand outward) through the threaded groove 22. Then, the bottom end of the drill bit 2 is placed in the clamping groove 19, and the annular protrusion 24 is clamped into the annular groove 23. Then, the nut 21 is rotated to the top end of the clamping groove 19 to clamp the separated clamping groove 19, so as to clamp and fix the bottom end of the drill bit 2. When the drill bit 2 is disassembled, the nut 21 is reversely rotated to the bottom end of the clamping groove 19. The top end of the clamping groove 19 expands outward and separates. Then, the drill bit 2 is taken out of the clamping groove 19. The operation is simple and convenient, the drill bit 2 can be quickly replaced, and the disassembly and assembly efficiency of the drill bit 2 is further improved.
