[0023] Specifically, an extension block 10 is fixedly connected to the outer side of the upper sampling body 8, and a sampling tool 9 is embedded inside the top of the upper sampling body 8. The height of the sampling tool 9 is set to four millimeters. The sampling tool 9 is made of a high-hardness and sharp material to ensure that the circular blade 16 can be cut quickly and cleanly in one go.

[0024] Furthermore, the lower part 4 and the upper sampling body 8 are rotatably connected, a circular hole groove is opened inside the lower part 4, and a test tube sleeve 13 is slidably set inside the circular hole groove of the lower part 4, which is convenient for collecting and storing circular leaf 16 samples and is very convenient for handheld operation.

[0026] It is worth noting that the bottom end of the upper sampling body 8 is tightly provided with a circular blade 16, and the shape and size of the sampling tool 9 is smaller than the size of the circular blade 16 to ensure accurate cutting. In addition, the sampling tool 9 can be disassembled, replaced and cleaned to facilitate the removal of blade residue and dust.

[0027] It is worth noting that an extension rod 11 is fixedly connected to the outer side of the support frame 1, and an ear-shaped support handle 12 is fixedly connected to the outer side of the extension rod 11. The ear-shaped support handle 12 is used to assist the staff to press downward.

[0029] Working principle:

[0030] First, the staff placed the test tube sleeve 13 inside the lower part 4 and adjusted it to a suitable position to ensure that the test tube sleeve 13 was clamped with the lower part 4. Then, according to the size of the sampling tool 9 at the bottom of the upper sampling body 8, the staff visually selected the circular leaf 16 to be sampled and placed it steadily at the bottom of the sampling tool 9. The staff rotated the sampling tool 9 to ensure that the circular leaf 16 could be cut. Then, the staff extended two fingers to the lower side of the ear-shaped handles 12 on both sides and pressed the extension block 10 on the outside of the upper sampling body 8. The third fixing seat 17 welded on the outside of the body 8 drives the internal connecting rod 5 to rotate to the right. This time, the upper sampling body 8 is perpendicular to the lower part 4. Then the upper sampling body 8 is moved again. The sampling tool 9 at the bottom end of the upper sampling body 8 cuts the circular blades 16. During the sampling process, pay attention to the cutting of the circular blades 16. The cut circular blades 16 samples fall into the interior of the test tube sleeve 13 for collection. The upper cover 14 at the top of the test tube sleeve 13 is closed, and the test tube sleeve 13 is pulled out from the interior of the lower part 4.
