[0010] This utility model provides a portable geological exploration drilling tool, which has the following beneficial effects:

[0011] 1. This portable geological exploration drill consists of a base, guide rod, first half-set, and second half-set. The user holds the handle and starts the motor, causing the motor's output to drive the drive shaft and the hollow sampling drill rod to rotate and drill into the soil through a through-hole for sampling. As the base moves downwards, it moves the second half-set and the first half-set along the outside of the guide rod, supporting and limiting the base's movement. This reduces the force required for the user to hold the drill firmly when drilling and sampling, making the drill easy to use.

[0021] The first half-set 14 is fixedly connected to both sides with a first threaded block 16, and the second half-set 15 is fixedly connected to both sides with a second threaded block 17. The second half-set 15 and the first half-set 14 are fixed together by the first threaded block 16 and the second threaded block 17.

[0022] Each of the first threaded blocks 16 is internally threaded with a second screw 18. One end of each second screw 18 extends into the interior of the second threaded block 17 and is threaded into the inner cavity of the second threaded block 17. The second screws 18 are used to limit and fix the first threaded block 16 and the second threaded block 17, as well as the second half-set 15 and the first half-set 14.

[0023] Both sides of the chassis 6 and one side of the mounting groove 10 are provided with threaded grooves 13. Each threaded groove 13 is threaded with a first screw 12. One end of each first screw 12 extends into the mounting groove 10. The first screw 12 limits and fixes the position of the mounting post 11 and the guide rod 19, so that the guide rod 19 can be installed on the top of the chassis 6.

[0024] Two side blocks 8 are fixedly connected to both sides of the chassis 6, and the position of the chassis 6 is fixed by the side blocks 8.

[0025] Example 2

[0026] Please see Figure 1 and Figure 3The present invention provides a technical solution: each side block 8 has a pin 9 inserted inside it, the top of each pin 9 extends to the top of the side block 8, and the bottom of each pin 9 extends to the bottom of the side block 8, so that the chassis 6 is limited to the ground by the pins 9 and the side blocks 8.

[0027] In summary, when using this portable geological exploration drill, take out the device, place the base 6 on the ground, drive the pin 9 into the ground using a tool, insert one end of the mounting post 11 at the bottom of the guide rod 19 into the mounting groove 10, and then screw one end of the first screw 12 into the threaded groove 13 and the mounting groove 10 to fix the position of the mounting groove 10 and the guide rod 19. Then take out the motor 1, place the base 2 on top of the base 6 so that the second half 15 is on one side of the guide rod 19, and then place the first half 14 on the other side of the guide rod 19. Then screw one end of the second screw 18 into the first threaded block 16 and the other end of the second screw 18 into the second threaded block 17. At this time, the user holds the handle 3 and starts the motor 1, so that the output end of the motor 1 drives the drive shaft 4 and the hollow sampling drill rod 5 to rotate and drill through the through hole 7. Sampling is performed in the soil. As the base 2 moves downward, it drives the second half-set 15 and the first half-set 14 to move along the outside of the guide rod 19, supporting and limiting the movement of the base 2. After sampling, the hollow sampling drill rod 5 is pulled out of the soil, allowing it to move through the through hole 7 to the top of the chassis 6. Then, the hollow sampling drill rod 5 is removed from the bottom of the drive shaft 4. One end of the second screw 18 is then unscrewed from the inside of the second threaded block 17, releasing the fixation between the second threaded block 17 and the first threaded block 16. The first half-set 14 is removed from one side of the guide rod 19. The base 2 is then removed from the top of the chassis 6. One end of the first screw 12 is then unscrewed from the inside of the mounting post 11, releasing the fixation between the mounting post 11 and the guide rod 19. The mounting post 11 at the bottom of the guide rod 19 is then pulled out of the mounting groove 10. Finally, the pin 9 is pulled out of the soil, thus disassembling the device for easy carrying by the user.
