The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] Please refer to the appendix carefully. Figure 1 , 2 As shown in Figure 5, in a preferred embodiment of the present invention, a micro fungal sampling device includes an n-shaped frame 10, a positioning block 11 disposed at the bottom of one end of the n-shaped frame 10, and a horizontal frame 12 with one end hinged to the positioning block 11 and the other end snapped onto the bottom of the n-shaped frame 10 away from the positioning block 11. The n-shaped frame 10 is provided with a self-deforming scraping device 20 in its inner ring, and the horizontal frame 12 is provided with a straight scraping device 30. The horizontal frame 12 is provided with a locking component 13 at one end near the positioning block 11. The locking component 13 includes a positioning nut 131 disposed on the outer wall of the horizontal frame 12, and a locking bolt 132 disposed on the side of the horizontal frame 12 away from the positioning nut 131. One end of the locking bolt 132 passes through the positioning block 11 and the horizontal frame 12 in sequence and is threadedly connected to the positioning nut 131. The outer wall of the n-shaped frame 10 is symmetrically provided with a first hanging handle 101, and the bottom of the horizontal frame 12 is provided with a second hanging handle 102.

[0039] It should be noted that, in this embodiment, the sampling device of the present invention has a small structure, which is convenient for sampling personnel to carry in their backpacks so that they can be taken to the field to collect fungal samples. When the sampling personnel need to sample the fungi on the dead branches, they can hold the first hanging handle 101 to use the self-deformation scraping device 20 for sampling, or they can hold the second hanging handle 102 to use the flat scraping device 30 for sampling.

When the flat scraping device 30 is used for sampling, it is convenient to sample a flat or limited area. The self-deformation scraping device 20 can also be used in combination with the flat scraping device 30 to perform ring-shaped scraping of samples.

[0040] Furthermore, when the n-shaped frame 10 is engaged with the horizontal frame 12, the self-deformable scraping device 20 and the straight scraping device 30 are combined. After the horizontal frame 12 rotates around its hinge point with the positioning block 11, the n-shaped frame 10 and the horizontal frame 12 are disengaged, which is the split state. The self-deformable scraping device 20 and the straight scraping device 30 can be used to take samples separately. The locking component 13 achieves the locking limit at the rotation point of the horizontal frame 12, so as to fix the horizontal frame 12 after the rotation adjustment is completed.

The first telescopic deformation adjustment component 22 includes a positioning frame 221 mounted on the top of the n-shaped frame 10, a movable tube 222 whose bottom end penetrates the n-shaped frame 10 and is slidably connected to it, and an adjusting rod 223 rotatably connected to the positioning frame 221 and whose bottom end is threadedly connected to the inner wall of the movable tube 222. The bottom of the movable tube 222 is connected to the outer wall of the n-shaped metal sheet 21. The second telescopic deformation adjustment component 22... The segment component 23 has the same structure as the first telescopic deformation adjustment component 22. The moving tube 222 in the second telescopic deformation adjustment component 23 is hinged to the outer wall of the n-shaped metal sheet 21. The first sampling bag upper bag component 25 includes multiple slide rails 251 embedded in the inner ring of the n-shaped metal sheet 21, an upper bag frame 252 slidably connected to the slide rails 251, a connecting rod 253 connected at one end to the upper bag frame 252, and a hand-held plate 254 provided at the other end of the connecting rod 253. The second sampling bag upper bag component 33 has the same structure as the first sampling bag upper bag component 25. The upper bag frame 252 includes an insert slidably connected to the slide rails 251. The connector 2521 includes a card plate 2522 at one end and an L-shaped plate 2523 at the other end. The outer wall of the L-shaped plate 2523 is connected to the connecting rod 253. The n-shaped blade 24 is connected to the n-shaped metal sheet 21 through a first mounting component 26. The straight blade 32 is connected to the U-shaped plate 31 through a second mounting component 34. The first mounting component 26 includes two mounting plates 261 symmetrically arranged on both sides of the bottom of the n-shaped blade 24, and a mounting bolt 262 with one end penetrating the mounting plate 261 and threadedly connected to the n-shaped metal sheet 21. The second mounting component 34 has the same structure as the first mounting component 26.

[0042] It should be noted that in this embodiment, the sampling operation mode of the self-deformable scraping device 20 is the same as that of the flat scraping device 30. Taking the sampling operation mode of the self-deformable scraping device 20 as an example, the sampling personnel first remove the first sampling bag upper bag component 25 and put the sampling bag on the first sampling bag upper bag component 25. The first sampling bag upper bag component 25 is inserted between the n-shaped metal piece 21 and the n-shaped blade 24 to complete the sampling bag upper bag operation. At this time, the shape of the n-shaped metal piece 21 and the n-shaped blade 24 are adjusted by the first telescopic deformation adjustment component 22 and the second telescopic deformation adjustment component 23. After adjusting to a suitable shape, sampling can begin. During sampling, the n-shaped blade 24 slashes across the surface of the branch, and the micro fungal sample enters the sampling bag through the n-shaped blade 24.

[0043] Furthermore, when loading the bag, the sampling bag can be a disposable shower cap structure. The bag body is placed between the L-shaped plate 2523 and the insertion plate 2521, and the bag opening is fitted onto the bag clamping plate 2522 and the outer wall of the L-shaped plate 2523. At this time, the personnel can insert the bag loading frame 252 into the slide rail 251 by holding the plate 254 to complete the bag loading operation. The bag loading method of the second sampling bag loading component 33 is the same as that of the first sampling bag loading component 25.

[0044] Furthermore, when the first telescopic deformation adjustment component 22 is working, the adjustment rod 223 is rotated, and the adjustment rod 223 drives the moving tube 222 to move up or down through the thread. The moving tube 222 pulls or squeezes the n-shaped metal sheet 21 to adjust the deformation. The working mode of the second telescopic deformation adjustment component 23 is the same as that of the first telescopic deformation adjustment component 22.

[0045] Furthermore, the first mounting component 26 facilitates the installation and removal of the n-shaped blade 24, and the second mounting component 34 facilitates the installation and removal of the straight blade 32. The working principle of the second mounting component 34 is the same as that of the first mounting component 26. Taking the operation of the first mounting component 26 as an example, the n-shaped blade 24 can be removed by unscrewing the mounting bolt 262.

[0046] Please refer to the appendix carefully. Figure 4 , 5As shown in Figures 7 and 8, in another preferred embodiment of the present invention, the outer wall of the n-shaped frame 10 is provided with a blade cleaning device 40. The blade cleaning device 40 includes a cleaning box 41 disposed on the outer wall of the n-shaped frame 10, a cleaning groove 42 embedded in the side wall of the cleaning box 41, magnetic blocks 43 symmetrically disposed on the inner wall of the cleaning groove 42, a blade wiping component 44 inserted into the cleaning groove 42, and a rinsing component 45 disposed on the top of the cleaning box 41 and communicating with the cleaning groove 42. The blade wiping component 44 includes a U-shaped wiping block 441 inserted into the cleaning groove 42, and a squeezing plate 442 located inside the U-shaped wiping block 441. The push rod 443, which is connected to the extrusion plate 442 through the U-shaped wiping block 441, includes a positioning ring 444 sleeved on the outer wall of the push rod 443, a spring 445 sleeved on the outer wall of the push rod 443 and located between the positioning ring 444 and the U-shaped wiping block 441, and a sponge pad 446 disposed inside the U-shaped wiping block 441. The rinsing component 45 includes a water inlet pipe 451 disposed on the top of the cleaning tank 41 and communicating with the cleaning tank 42, a drain pipe 452 disposed on the bottom of the cleaning tank 41 and communicating with the cleaning tank 42, and a connecting water cover 453 disposed on the water inlet end of the water inlet pipe 451.

[0047] It should be noted that, in this embodiment, when cleaning the blade, the blade wiping component 44 is pulled out from the cleaning groove 42, and the blade can be cleaned by the blade wiping component 44. After cleaning, the blade wiping component 44 is inserted into the cleaning groove 42, and the magnetic block 43 magnetically fixes the blade wiping component 44. At this time, the rinsing component 45 can be used to rinse and clean the blade wiping component 44.

[0048] Furthermore, when the blade wiping component 44 is working, the sampling personnel hold the push rod 443. When the blade is inside the U-shaped wiping block 441, the sponge pad 446 inside the U-shaped wiping block 441 can wipe the blade.

[0049] Furthermore, when the blade wiping component 44 is cleaning, the water cap 453 is connected to the mouth of the mineral water bottle. Water is discharged after passing through the water inlet pipe 451, the cleaning tank 42 and the drain pipe 452. The U-shaped wiping block 441 located in the cleaning tank 42 is cleaned. At the same time, the push rod 443 can be manually pushed. The push rod 443 squeezes the sponge pad 446 through the squeezing plate 442 so that the sponge pad 446 can be cleaned. The spring 445 can drive the push rod 443 to reset through the positioning ring 444.

[0050] The specific process of this invention is as follows:

[0051] The sampling device in this invention is compact and easy for sampling personnel to carry in their backpacks for fungal sample collection in the field. When the sampling personnel need to sample fungi on dead branches, they can hold the first handle 101 to use the self-deformation scraping device 20 for sampling, or they can hold the second handle 102 to use the flat scraping device 30 for sampling. When the self-deformation scraping device 20 is used for sampling, it is convenient to scrape samples from a large area of ​​the outer wall of different dead branches. When the flat scraping device 30 is used for sampling, it is convenient to sample from a flat or limited area. The self-deformation scraping device 20 can also be used in combination with the flat scraping device 30 for ring-shaped scraping of samples.

[0052] When the n-shaped frame 10 and the horizontal frame 12 are engaged, the self-deformable scraping device 20 and the straight scraping device 30 are combined. After the horizontal frame 12 rotates around the hinge point with the positioning block 11, the n-shaped frame 10 and the horizontal frame 12 are disengaged, which is the split state. The self-deformable scraping device 20 and the straight scraping device 30 can be used to take samples separately. The locking component 13 locks and limits the rotation of the horizontal frame 12 to facilitate the fixation after the horizontal frame 12 has been adjusted. When the locking component 13 is working, the locking bolt 132 is rotated, and the nut of the locking bolt 132 moves closer to the positioning nut 131. The positioning nut 131 and the locking bolt 132 generate a clamping force to achieve locking.

[0053] The sampling operation mode of the self-deformable scraping device 20 is the same as that of the flat scraping device 30. Taking the sampling operation mode of the self-deformable scraping device 20 as an example, the sampling personnel first remove the first sampling bag upper bag component 25 and put the sampling bag on the first sampling bag upper bag component 25. The first sampling bag upper bag component 25 is inserted between the n-shaped metal piece 21 and the n-shaped blade 24 to complete the sampling bag upper bag operation. At this time, the shape of the n-shaped metal piece 21 and the n-shaped blade 24 are adjusted by the first telescopic deformation adjustment component 22 and the second telescopic deformation adjustment component 23. After adjusting to the appropriate shape, sampling can begin. During sampling, the n-shaped blade 24 scrapes across the surface of the branch, and the micro fungal sample enters the sampling bag through the n-shaped blade 24.

[0054] When loading the bag, the sampling bag can be a disposable shower cap structure. The bag body is placed between the L-shaped plate 2523 and the insertion plate 2521, and the bag opening is fitted onto the bag clamping plate 2522 and the outer wall of the L-shaped plate 2523. At this time, the personnel can insert the bag loading frame 252 into the slide rail 251 by holding the plate 254 to complete the bag loading operation. The bag loading method of the second sampling bag loading component 33 is the same as that of the first sampling bag loading component 25.

[0055] When the first telescopic deformation adjustment component 22 is working, the adjustment rod 223 is rotated. The adjustment rod 223 drives the moving tube 222 to move up or down through the thread. The moving tube 222 pulls or squeezes the n-shaped metal sheet 21 to adjust the deformation. The working mode of the second telescopic deformation adjustment component 23 is the same as that of the first telescopic deformation adjustment component 22.

[0056] The first mounting component 26 facilitates the installation and removal of the n-shaped blade 24, and the second mounting component 34 facilitates the installation and removal of the straight blade 32. The working principle of the second mounting component 34 is the same as that of the first mounting component 26. Taking the operation of the first mounting component 26 as an example, the n-shaped blade 24 can be removed by unscrewing the mounting bolt 262.

[0057] When cleaning the blade, pull out the blade wiping component 44 from the cleaning tank 42 and use the blade wiping component 44 to clean the blade. After cleaning, insert the blade wiping component 44 back into the cleaning tank 42. The magnetic block 43 magnetically holds the blade wiping component 44 in place. At this time, the rinsing component 45 can be used to rinse and clean the blade wiping component 44.

[0058] When the blade wiping component 44 is working, the sampling personnel hold the push rod 443. When the blade is inside the U-shaped wiping block 441, the sponge pad 446 inside the U-shaped wiping block 441 can wipe the blade.

[0059] When the blade wiping component 44 is cleaning, the water cap 453 is connected to the mouth of the mineral water bottle. Water is discharged after passing through the water inlet pipe 451, the cleaning tank 42 and the drain pipe 452. The U-shaped wiping block 441 located in the cleaning tank 42 is cleaned. At the same time, the push rod 443 can be manually pushed. The push rod 443 squeezes the sponge pad 446 through the squeezing plate 442 so that the sponge pad 446 can be cleaned. The spring 445 can drive the push rod 443 to reset through the positioning ring 444.
