Through the provision of the square hole, the square column 15 is interlaced and connected with the square hole provided on the surface of the sampling tube 1, so that the square column 15 will not change its angle with the rotation of the plum blossom knob 4, and the handle 2 rotates ninety degrees, and the square sleeve 16 of the handle 2 can still remain corresponding to the square column 15 after the ninety-degree rotation, so that the square sleeve 16 and the square column 15 are easy to plug in.

[0031] Working principle:

[0032] When in use, the sampling tube 1 is placed in the soil sampling area of ​​the tobacco field, and the handle 2 on the upper part of the sampling tube 1 is pressed and rotated, so that the several arc-shaped teeth 14 surrounding the bottom port of the sampling tube 1 cut the soil in an annular manner, so that the soil of the tobacco field enters the sampling tube 1 in a cylindrical shape. When the soil collection depth of the sampling tube 1 reaches the required depth, the sampling tube 1 is pulled out and the protrusion 8 in the strip-shaped opening 7 is pressed downward, so that the pushing disc 11 fixed to the protrusion 8 presses down the collected columnar soil sample. In combination with the soil storage box 5 that is sleeved with the connecting sleeve 6 and the bottom of the sampling tube 1, the columnar soil sample pushed out by the pushing disc 11 can be collected in the soil storage box 5. Inside, when storing, by rotating the handle 2 on the upper part of the sampling tube 1 by 90 degrees, the support column 17 on one side surface of the handle 2 and the shaft seat 18 installed on the inner wall of the sampling tube 1 are caused to rotate relative to each other, so that the handle 2 is converted from a horizontal state to a vertical state until the handle 2 is hidden inside the sampling tube 1, and then the plum blossom knob 4 screwed on the surface of the support seat 3 is rotated, so that the square column 15 connected by a bearing at one end of the plum blossom knob 4 is close to the handle 2 until the square column 15 is plugged into the square sleeve 16 on the other side surface of the handle 2, thereby achieving the purpose of hiding and locking the handle 2, reducing the space occupied by the sampling tube 1 in a foldable storage manner, and increasing the portability of the sampling tube 1.
