The outer diameter of the sampling column 22 is the same as the inner diameter of the outer sleeve 21. Specifically, in the actual execution process, when soil is collected, the plurality of support columns 12 are inserted into the soil, the support plates 11 are attached to the top surface of the soil, the outer sleeve 21 is rotated by a worker, the outer sleeve 21 gradually moves down under the action of the saw tooth part 4, and the sampling columns 22 synchronously move down along with the outer sleeve 21 while the outer sleeve 21 moves down.

The guide holes 3 enable the outer sleeve 21 not to deviate easily in the downward moving process, so that the outer sleeve 21 always keeps a vertical state. After the outer sleeve 21 moves to the depth position where the soil sample needs to be collected, the staff controls the sampling column 22 to move downwards and extend out of the outer sleeve 21 through the adjusting component 24 until the sampling groove 5 is separated from the outer sleeve 21, soil at the corresponding depth position can enter the sampling groove 5, after the soil sample is collected, the staff controls the sampling column 22 to move upwards through the adjusting component 24, a closed space is formed between the sampling groove 5 and the outer sleeve 21 again, and then the outer sleeve 21 is pulled out of the soil.
