A circular plate 10 is fixedly arranged at the bottom of the connecting column 6, and is used to mount the sampling device body 1 on the top of the mounting plate 4 later.

[0034] The mounting assembly is a key component for realizing the rapid installation and disassembly of the sampling device body 1 and the mounting plate 4. The mounting assembly includes an adjustment plate 5 and a plurality of moving rods 8. The adjustment plate 5 is arranged below the mounting plate 4, and a plurality of bevel grooves 12 arranged in an annular shape and at equal intervals are provided on the top thereof. The bottom ends of the plurality of moving rods 8 are respectively slidably provided inside the plurality of bevel grooves 12, and can slide in the bevel grooves 12. The surface of the mounting plate 4 is provided with a plurality of limiting grooves 11 arranged in an annular shape and at equal intervals, and the top ends of the plurality of moving rods 8 respectively extend to the interior of the plurality of limiting grooves 11 and cooperate with each other, and the moving rods 8 are moved outward by rotating the adjustment plate 5. A baffle 13 cooperating with the circular plate 10 is fixedly provided on the top of the outer wall of the moving rod 8, and is used to block the circular plate 10 through the baffle 13 when the moving rod 8 moves to the outer end of the limiting groove 11, thereby realizing the fixation of the sampling device body 1 and the mounting plate 4.

[0035] In addition, the mounting assembly also includes a plurality of annular slots 9 equidistantly arranged on the outer wall of the circular plate 10, and a card plate 14 fixed to the bottom of the baffle 13 and matching with the slots 9. When the sampling device body 1 is installed in place, the card plate 14 will be inserted into the slots 9, further increasing the stability and firmness of the installation.

[0036] Specifically, the adjusting plate 5 is rotated, and the adjusting plate 5 drives the moving rod 8 to move the outer end of the limiting groove 11 through the inclined groove 12. Then, the card slot 9 below the sampling device body 1 is aligned with the positioning rod 7 and placed on the top of the mounting plate 4. Then, the moving rod 8 is moved back to its original position through the resetting of the torsion spring 20, and the installation of the sampling device body 1 is completed. When disassembling, it is only necessary to rotate the adjusting plate 5 to complete the disassembly. There is no need for cumbersome operations through threads and the trouble of installing and disassembling with screws and tools, which makes it more convenient for practical use.
