[0039] Move the device to the location where sampling is required, place the fixed base 1 at the designated sampling location, unscrew the positioning screw 15, and move the support plate 6. One end of the support plate 6 rotates axially around the first connecting ear plate 8, and the end of the support rod 11 near the third connecting ear plate 12 rotates axially around the third connecting ear plate 12. The end of the support rod 11 near the second connecting ear plate 10 rotates axially around the second connecting ear plate 10. The slider 9 slides vertically downward along the first slide groove 13, and the connecting plate 14 moves vertically downward with the slider 9 to the threaded hole at the lower end of the side wall of the fixed base 1 on the vertical movement path of the connecting plate 14. Tighten the positioning screw 15 to fix the position of the slider 9 in the first slide groove 13, and support the support plate 6. The bottom surface of the support plate 6 is aligned with the sampling point. When the surfaces are in contact, insert the fixing nail 7. The fixing nail 7 passes through the perforation on the support plate 6 and is inserted into the ground at the collection point to fix the position of the fixing seat 1. If the rectangular opening 5 at the bottom end of the outer sleeve 2 and the rectangular opening 5 at the bottom end of the inner sleeve 3 coincide, that is, unscrew the locking screw 24 and press down the lever 26. The lever 26 slides vertically downward along the third slide groove 25. The stop block 21 slides vertically downward along the second slide groove 23 with the lever 26. The locking rod 20 moves vertically downward with the stop block 21 and is pulled out from the insertion hole at one end of the handle 4. Rotate the handle 4, which in turn drives the inner sleeve 3 to rotate, so that the rectangular opening 5 at the bottom end of the inner sleeve 3 is misaligned with the rectangular opening 5 at the bottom end of the outer sleeve 2. Then, reinsert the locking rod 20 into the insertion hole at the other end of the handle 4 and tighten the locking screw 24. 4. Fix the position between the inner sleeve 3 and the outer sleeve 2. Insert the ring 16 into the inside of the fixing seat 1 through the insert block 17. Tighten the connecting screw 19 to fix the position of the ring 16. Pass the outer sleeve 2 through the ring 16. The operator holds both ends of the handle 4 and presses down the handle 4, which in turn drives the inner sleeve 3 down, which in turn drives the outer sleeve 2 down. The ring 16 guides the outer sleeve 2 to prevent it from deviating during drilling. The operator observes the position of the pointer 27 pointing to the scale line on the surface of the outer sleeve 2 to control the drilling depth of the outer sleeve 2. When the required soil depth is reached, unscrew the locking screw 24 and press down the lever 26. The lever 26 slides vertically downward along the third slide groove 25. The stop block 21 moves vertically along the second slide groove 23 with the lever 26. Slide downwards, and the locking rod 20 moves vertically downwards with the stop block 21, being pulled out from the insertion hole at one end of the handle 4. Rotate the handle 4, which in turn drives the inner sleeve 3 to rotate, so that the rectangular opening 5 at the bottom end of the inner sleeve 3 coincides with the rectangular opening 5 at the bottom end of the outer sleeve 2. Then, reinsert the locking rod 20 into the insertion hole at the other end of the handle 4, tighten the locking screw 24, and fix the position between the inner sleeve 3 and the outer sleeve 2. Then, rotate the handle 4, and the inner sleeve 3 rotates with the handle 4. The rotation of the inner sleeve 3 drives the outer sleeve 2 to rotate in the soil. The soil enters the inner cavity of the inner sleeve 3 through the rectangular opening 5 of the outer sleeve 2 and the inner sleeve 3. After sampling is completed, unscrew the locking screw 24 again and press down the paddle 26. The paddle 26 slides vertically downwards along the third sliding groove 25.The stop block 21 slides vertically downward along the second slide groove 23 with the paddle 26. The locking rod 20 moves vertically downward with the stop block 21 and is pulled out from the insertion hole at one end of the handle 4. The handle 4 is rotated, which in turn drives the inner sleeve 3 to rotate, so that the rectangular opening 5 at the bottom end of the inner sleeve 3 is misaligned with the rectangular opening 5 at the bottom end of the outer sleeve 2. Then, the locking rod 20 is reinserted into the insertion hole at the other end of the handle 4, and the locking screw 24 is tightened to fix the position between the inner sleeve 3 and the outer sleeve 2. Then, the outer sleeve 2 is moved upward, which drives the inner sleeve 3 to move upward, that is, the outer sleeve 2 is pulled out of the ring 16, and the locking screw 24 is unscrewed. Press the lever 26, which slides vertically downward along the third groove 25. The stop block 21 slides vertically downward along the second groove 23 with the lever 26. The locking rod 20 moves vertically downward with the stop block 21 and is pulled out from the insertion hole at one end of the handle 4. Rotate the handle 4, which in turn rotates the inner sleeve 3, causing the rectangular opening 5 at the bottom of the inner sleeve 3 to coincide with the rectangular opening 5 at the bottom of the outer sleeve 2. Then, reinsert the locking rod 20 into the insertion hole at the other end of the handle 4 and tighten the locking screw 24 to fix the position between the inner sleeve 3 and the outer sleeve 2. The soil inside the inner sleeve 3 can then be removed, completing the sampling process.
