[0031] Detailed usage and function of this embodiment: After the device is placed in a suitable position, the drive motor 39 is operated, and the motor 39 drives the threaded rod 40 to rotate. The force-dividing cylinder 41 will move to one side with the rotation of the threaded rod 40, and the T-shaped guide column 44 will press the spring 3 17 to move into the column 2, and then the tightening nut 50 is tightened, the threaded locking rod 49 is fastened in the threaded hole 48, and the limiting rod 51 at the center of the side of the locking plate 47 is slid in the V-groove 53 and limited to the groove below the V-groove 53. At this time, the force-dividing top plate 52 is limited and locked. As the T-shaped guide column 44 moves to one side of the column 2, one side of the force-dividing top plate 52 will support the side of the column 2. When the drill rod 12 is performing a sampling operation, the generated The vibration force will be transmitted from the force-dividing top plate 52 to the T-shaped guide column 44. After the inner column 13 is subjected to the vibration force, it will be transmitted to the spring three 17 connected to the side along with the first force-bearing plate 15 and the second force-bearing plate 16. The spring three 17 will decompose the transmitted force to increase the transmission path, and there is a certain distance between the T-shaped guide column 44 and the L-shaped seat 38 and the column 2. Therefore, there will be a fault between the three. No matter which one directly generates the force, it will not be directly transmitted to another component. In this way, the stability of the support foot 45 supporting the ground will be enhanced.

When the internal threaded tube 28 sleeved on the threaded rod 26 moves upward, the connecting plate 31 connected to the internal threaded tube 28 presses the driving arm 35 inserted in the middle, and the bottom of the driving arm 35 pulls the side drilling plate 34. The side drilling plate 34 As the upper part expands outward and the bottom descends, the bottom of the side drilling plate 34 is inserted into the soil, and the outer wall of the side drilling plate 34 presses the inner wall of the soil. After the drill rod 12 drills into the soil, the soil is sampled and the extracted soil is stored in the sampling tube 11, wherein a telescopic structure is provided between the drill rod 12 and the sampling tube 11, and the drill rod 12 is a spiral conveying slurry. During the drilling operation, the threaded conveying slurry structure conveys the drilled soil upward to the sampling tube 11 connected to the upper part for storage. After the drill rod 12 is extended and retracted, the lower part of the sampling tube 11 is blocked, and then the reverse drive motor 25 is operated to close and merge the side drilling plate 34 expanded on the side, and then the entire device is extracted.
