By pulling the pull plate 13 upward, the second fixing ring 10 drives the third support plate 9 to move upward through the pulling plate 13, and the third support plate 9 pulls the first support plate 7 to move upward, so that the first support plate 7 drives the second support plate 8 to expand outward through the third support plate 9, so that the second support plate 8 is flush with the protective tube 4, and the second fixing ring 10 presses the limit block 11 toward the inside of the threaded tube 5, so that the limit spring 12 is compressed and shortened. When the second fixing ring 10 moves to the top of the limit block 11, the limit block 11 rebounds to its original position by the elastic force of the limit spring 12, so that the bottom of the second fixing ring 10 abuts against the top of the limit block 11, and the protective tube 4 is vertically placed at the position where sampling is required. The second support plate 8 abuts the ground, and by rotating the gripping rod 3, the threaded rod 2 drives the soil sampling barrel 1 to rotate and press down, and the soil can be sampled through the soil sampling barrel 1. The protective tube 4 protects the soil sampling barrel 1 and limits the movement of the soil sampling barrel 1 to prevent the soil sampling barrel 1 from bending when it descends. The soil sampling barrel 1 is supported by the second support plate 8, so that the soil sampling barrel 1 is more stable when it descends to take soil. When not in use, the arc surfaces of the first support plate 7 and the second support plate 8 are both in contact with the protective tube 4.

The soil sampling tube 1 can be made to descend linearly through the protective tube 4. The soil sampling tube 1 and the protective tube 4 can be supported and fixed by the first support plate 7 and the second support plate 8, which can avoid the soil sampling tube 1 from vertically descending due to different forces applied manually. When not in use, the soil sampling tube 1 and the protective tube 4 are protected by the first support plate 7 and the second support plate 8.

As shown in Figures 1, 3 and 4, the inner diameter of the second support plate 8 is equal to the outer diameter of the protective tube 4, the third support plate 9 is an arc structure, the middle part of the second fixing ring 10 is movably connected to the threaded tube 5, and one end of the limit spring 12 is fixedly connected to the inside of the threaded tube 5;

The first support plate 7 is pulled to move and extend by the third support plate 9, and the second fixing ring 10 moves along the wall of the threaded tube 5. The limiting block 11 is supported by the limiting spring 12, and the limiting block 11 is pressed by the second fixing ring 10, so that the limiting spring 12 is compressed and shortened, and the limiting block 11 is rebounded to its original position by the limiting spring 12, so that the limiting block 11 limits and fixes the second fixing ring 10. When not in use, the limiting block 11 is pressed so that the limiting block 11 is pressed into the slot, and the second fixing ring 10 is moved downward by pulling down the pull plate 13.

As shown in FIG. 2 and FIG. 4 , the limit block 11 is a trapezoidal structure tilted upward from left to right, a slot matching the size of the limit block 11 is provided inside the threaded barrel 5, the limit plate 14 is located directly above the second fixing ring 10, and the outer portion of the pull plate 13 is movably engaged with the limit plate 14;

The second fixing ring 10 is pulled by the pulling plate 13 to limit the movement of the pulling plate 13 through the limiting plate 14, the limiting block 11 is accommodated through the card slot, and the second fixing ring 10 is limited and fixed by the limiting block 11 and the limiting plate 14 to prevent the second fixing ring 10 from moving upward when the soil-taking barrel 1 descends.

The working principle and use process of this utility model:

First, the staff pulls the pull plate 13 upwards, and the second fixing ring 10 drives the third support plate 9 to move upwards through the pulling plate 13. The third support plate 9 pulls the first support plate 7 to move upwards, so that the first support plate 7 drives the second support plate 8 to expand outwards through the third support plate 9, so that the second support plate 8 is flush with the protective tube 4, and the second fixing ring 10 presses the limit block 11 against the inside of the threaded tube 5, so that the limit spring 12 is compressed and shortened.
