When the sampling cylinders 13 are rotated outward via a hinge 14, the two sampling cylinders 13 separate, facilitating cleaning of the deeper parts of the sampling cylinders 13. The sampling cylinders 13 are connected to the sampling rod 11 via the hinge 14. An insert rod 15 is inserted into the interior of the upper part of the sampling cylinder 13. The insert rod 15 passes through the hole in the sampling rod 11 and is inserted into the groove of the sampling cylinder 13, which can limit the position of the sampling cylinder 13. A slip ring 16 is installed above the insert rod 15. A first magnetic ring 17 is located on the inner side below the slip ring 16. A second magnetic ring 18 is attracted below the first magnetic ring 17.
[0027] Furthermore, the auxiliary component 02 includes a fixed ring 21, and a rotating ring 22 is connected to the outer wall of the fixed ring 21. The rotating ring 22 can rotate around the fixed ring 21, thereby adjusting the position of the pedal 23 for easy stepping by the staff. Pedals 23 are provided at both ends of the rotating ring 22. The pedals 23 are connected to the rotating ring 22 by bolts 24. The bolts 24 can be screwed into the rotating ring 22 through the holes of the pedals 23 to fix the position of the pedals 23.
[0028] Furthermore, the push rod 12 is slidably connected to the sampling rod 11, and the sampling cylinder 13 is rotatably connected to the sampling rod 11 via the hinge 14. When the sampling cylinder 13 is rotated outward via the hinge 14, the two sampling cylinders 13 are separated, which facilitates cleaning of the deep part of the sampling cylinder 13. The sampling cylinder 13 has a groove corresponding to the insertion rod 15. The insertion rod 15 passes through the hole of the sampling rod 11 and is inserted into the groove of the sampling cylinder 13, which can limit the position of the sampling cylinder 13.
[0029] Furthermore, the sampling rod 11 has a hole corresponding to the insertion rod 15, and the slip ring 16 is fixedly connected to the insertion rod 15. The insertion rod 15 passes through the hole of the sampling rod 11 and is inserted into the groove of the sampling cylinder 13, which can limit the position of the sampling cylinder 13.

[0031] Furthermore, the fixed ring 21 is fixedly connected to the sampling rod 11 to ensure the stability of the fixed ring 21. The rotating ring 22 is rotatably connected to the fixed ring 21, and the rotating ring 22 can rotate around the fixed ring 21 to adjust the position of the pedal 23, making it convenient for staff to step on it.
[0032] Furthermore, the pedal 23 has a hole corresponding to the bolt 24. The bolt 24 is threadedly connected to the swivel ring 22. The bolt 24 can be passed through the hole of the pedal 23 and screwed into the swivel ring 22 to fix the position of the pedal 23.
[0033] Working principle: When in use, first insert the sampling cylinder 13 into the soil. If hard soil is encountered, rotate the rotating ring 22 around the fixed ring 21, and rotate the pedal 23 to a position convenient for the worker to step on. The worker steps on the pedal 23 downwards, allowing the sampling cylinder 13 to continue being inserted into the hard soil. After removing the sampling cylinder 13, stabilize the sampling rod 11 and move the push rod 12. The push rod 12 will push the soil out of the sampling cylinder 13. When cleaning the sampling cylinder 13, grasp the sliding ring 16 and lift it upwards along the sampling rod 11. The first magnetic ring 17 and the second magnetic ring 18 separate. The sliding ring 16 drives the insertion rod 15 to move, disengaging the insertion rod 15 from the groove of the sampling cylinder 13. The sampling cylinder 13 is then rotated outwards via the hinge 14, separating the two sampling cylinders 13. The above is the complete working principle of this utility model.
