[0028] In this embodiment, the outer circumference of the drill bit 14 is provided with several grooves 17, auxiliary drill blocks 18 are respectively arranged in the grooves 17, through grooves 19 connected to the inner cavity 15 are respectively provided in the grooves 17, and levers 20 are respectively arranged in the through grooves 19. A block 21 is provided in the inner cavity 15, and the levers 20 are respectively fixedly installed on the block 21. The outer ends of the levers 20 are respectively in contact with the corresponding auxiliary drill blocks 18, and the contact surfaces between the auxiliary drill blocks 18 and the levers 20 are inclined surfaces. Several spring rods 22 are fixedly installed on the bottom surface of the inner cavity 15, and the spring rods 22 are all fixedly connected to the block 21.

[0029] In this embodiment, slide grooves 23 are respectively provided on both sides of the groove 17 , and sliding blocks 24 are respectively provided in the slide grooves 23 , and the sliding blocks 24 are respectively fixedly mounted on the auxiliary drill blocks 18 .

Specifically, the controller 27 is a Siemens PLC controller, and the controller 27 is respectively connected to the hydraulic rod 6, the first solenoid valve 10, the second solenoid valve 12 and the laser rangefinder 26 through circuits.

[0033] In this embodiment, handles 28 are fixedly mounted on both sides of the main water tank 1 .

Through this device, the impact force of the high-pressure water flow and the gravity of the water are used as the drive, which can reduce the force applied by people during drilling, and achieve the effect of facilitating drilling while saving effort. In addition, through the extension and retraction of the auxiliary drill block 18, the borehole can be expanded, and the water flow can be blocked by the auxiliary drill block 18 to reduce water splashing.
