When the guide tube 21 abuts against the baffle 221, the end of the drill bit 15 is flush with the end of the guide tube 21 facing away from the baffle 221. A flange 211 is integrally formed at an end of the guide tube 21 facing away from the baffle 221. In the initial state, the guide tube 21 abuts against the baffle 221, and the drill bit 15 is just capable of contacting the ground. By moving the positioning ring 23, the depth to be drilled into the ground is marked on the guide rod 22. The distance between the positioning ring 23 and the flange 211 is the distance that the drill bit 15 can penetrate into the ground, and when the guide tube 21 moves to abut against the positioning ring 23, the drill bit 15 stops feeding.
