[0023] The clamping member 7 includes a fixed ring 701. Three clamping jaws 702 are rotatably installed on the outer wall of the fixed ring 701 in a circumferential array. At the lower ends of the three clamping jaws 702, clamping blocks 703 that are combined with the docking sleeve 6 are constructed downward; the combination of the clamping blocks 703 and the docking sleeve 6 can limit the connection position between the docking sleeve 6 and the limiting block 5 to achieve the effect of clamping connection.

[0029] Working principle: This embodiment provides a portable geological exploration drilling device. Before use, the drill pipe main body 4 is assembled first. First, the docking sleeve 6 at the top of the connecting pipe 402 is inserted into the bottom of the fixed pipe 401 so that the limiting block 5 is docked with the limiting groove 601. Then, the connecting ring 8 can be manually pressed to make the connected adjusting block 704 be pressed and move closer to the center of the drill pipe main body 4, so that the three clamping jaws 702 can expand outwards, and the side end of the clamping block 703 can be moved to the outside of the docking sleeve 6, which does not affect the upward movement of the docking sleeve 6. When the docking sleeve 6 moves in place, the position of the clamping block 703 can be aligned with the position of the clamping groove 602. Under the elastic action of the connecting ring 8 and the spring 9, the clamping jaws 702 drive the clamping block 703 to reset, so as to be clamped into the inside of the clamping groove 602, thereby fixing the position of the connecting pipe 402 and completing the assembly operation. Then, multiple connecting pipes 402 can be connected in sequence to reach the required exploration length. Finally, the drilling pipe 403 is fixed at the lower end of the connecting pipe 402 in the same way, so as to complete the overall assembly. Such a connection method can be disassembled and separated in sequence after the drilling operation, so as to extract the soil inside the drill pipe main body 4. The segmented method can improve the accuracy of soil exploration at different depths, reduce the probability of soil mixing, and is also convenient for cleaning, reduce the occurrence of blockage, effectively reduce the time required for soil extraction, and is easy to use.
