The method of knocking the sampling tube 1 is not only very inconvenient, but also takes a lot of time.
[0027] After the sample soil is taken out, the several sections of the branch pipe 101 are first separated by the connecting component 5. At this time, the user rotates the push block 7 to make it rotate in the annular placement groove 6. The rotating push block 7 will drive the second connecting rod 23 to rotate together. At this time, the vertically arranged second connecting rod 23 will drive the scraper plate 21 that is tightly attached to the inner wall of the branch pipe 101 to rotate together through the first connecting rod 22.
