The inner diameter size of the positioning hole 47 is adapted to the outer diameter size of the positioning head 39. It should be noted that the plurality of boxes 41 can collect and store samples of various soil layers, and through the cooperation of the positioning head 39 and the positioning hole 47, the position of the stored box 41 can be flexibly adjusted to facilitate the rapid switching of the box 41.

[0028] As Figures 6-7As shown, a fixing column 301 is connected to the top end of the support column 33. A limit seat 302 is arranged on the outer surface of the fixing column 301. An installation groove 303 is formed on the surface of the limit seat 302. A sliding groove 308 is formed at the corresponding position of the bottom surface of the limit seat 302 and the sliding path of the slider 44. Two moving grooves 304 are formed on the outer surface of the limit seat 302. One end of each of the two moving grooves 304 is communicated with the installation groove 303.
