The sliding grooves 101 are located on the lower tube body 1 above the sealing film 5.

[0032] A first limiting ring 6 is provided on the outer edge of the open end of the lower tube body 1, and a second limiting ring 7 corresponding to the first limiting ring 6 is provided on the part of the upper tube body 2 extending outside the lower tube body 1. A detachable support assembly 8 is clamped between the first limiting ring 6 and the second limiting ring 7, and a docking locking assembly 9 is further provided between the lower surface of the second limiting ring 7 and the first limiting ring 6; the detachable support assembly 8 includes support blocks 801 circumferentially spaced between the first limiting ring 6 and the second limiting ring 7, a breakable connection strip 802 is connected between the support blocks 801, and a pull ring 803 is further provided on the outer wall of the support blocks 801; the docking locking assembly 9 is located on the first limiting ring 6 and the second limiting ring 7 between adjacent support blocks.

[0033] The docking and locking assembly 9 includes a locking hole 901 penetrating through the first limiting ring 6. A locking block 902 corresponding to the position of the locking hole 901 is provided at the lower part of the second limiting ring 7. Several elastic limiting components are provided at the bottom of the locking block 902. The elastic limiting component includes a rotating cavity 903 penetrating through the side of the locking block 902. A limiting block 904 is rotatably connected in the rotating cavity 903. The bottom of the limiting block 904 is rotatably connected to the rotating cavity 903 through a rotating shaft 905. A torsion spring for protruding the limiting block 904 out of the rotating cavity 903 is provided on the rotating shaft 905. The top of the part of the limiting block 904 protruding out of the rotating cavity 903 is a flat plate, and the side part is an inclined surface inclined towards the bottom of the locking block 902.

[0034] The sampling assembly 3 includes a sampling handle 301. One end of the sampling handle 301 is threadedly connected to the end of the upper tube body 2 far from the lower tube body 1 through an operating handle 302, and the other end is provided with a sampling head 303 extending into the conical puncturing end 4.

[0035] A third limiting ring 10 is provided on the outer wall of the end of the upper tube body 2 far from the lower tube body 1. A protective cover 11 of the sampling assembly 3 is detachably connected between the third limiting ring 10 and the end of the upper tube body 2. An inner first thread 201 is provided on the inner side of the top opening of the upper tube body 2, and an outer first thread 202 is provided on the outer side. The operating handle 302 includes a connecting handle 302a connected to the top of the upper tube body 2. A holding handle 302b is provided at one end of the connecting handle 302a far from the sampling head 303. A second outer thread 302c matching the first inner thread 201 is provided on the outer wall of the connecting handle 302a. When the connecting handle 302a is fully screwed into the upper tube body 2, the sampling head 303 extends out of the conical puncturing end 4. In the initial state, a part of the second outer thread 302c of the connecting handle 302a is screwed with the first inner thread 201 on the upper part of the upper tube body 2, so that the sampling head 303 is suspended in the conical puncturing end 4. The protective cover 11 is externally fitted and connected to the first outer thread 202, and a second inner thread 1101 matching the first outer thread 202 is provided on the inner wall of the protective cover 11.

[0036] During specific implementation, first, remove the protective cover 11 from the outside of the upper tube body 2, hold the holding handle 302b by hand, take out the sampling assembly 3 from the upper tube body 2, and perform corresponding sampling operations such as wiping and scraping according to the sample type and collection requirements to ensure that the sampling head 303 fully collects the sample.

[0037] Then, reinstall the sampling component 3 into the upper tube body 2. At this time, hold the pull ring 803 by hand and pull it outward with uniform force to break the breakable connecting strip 802, so that the support blocks 801 are separated from each other and taken out from between the first limiting ring 6 and the second limiting ring 7. At this time, the supporting effect between the first limiting ring 6 and the second limiting ring 7 disappears, and the upper tube body 2 can move relative to the lower tube body 1. Hold the second limiting ring 7 part of the upper tube body 2 and slowly push the upper tube body 2 downward so that the piercing tip 401 of the conical piercing end 4 contacts and pierces the sealing film 5, and the sample processing liquid flows out from the rupture of the sealing film 5 and enters the upper space of the lower tube body 1. At the same time, align the locking block 902 with the locking hole 901 and continue to press the upper tube body 2 downward, and the locking block 902 enters the locking hole 901. During the process of the locking block 902 entering the locking hole 901, the inclined surface of the limiting block 904 contacts the edge of the locking hole 901. After being squeezed, the limiting block 904 rotates around the rotating shaft 905. After entering the locking hole 901, under the action of the torsion spring, the limiting block 904 protrudes from the rotating cavity 903, and the flat part catches the locking hole 901 to realize the locking of the upper tube body 2 and the lower tube body 1 and prevent relative movement between the two.

[0038] Then, through the cooperation of the threads, screw the connecting handle 302a completely into the upper tube body 2 to move the sampling component 3 downward, so that the sample collected on the sampling head 303 is fully mixed with the sample processing liquid to ensure that the sample is evenly dispersed in the processing liquid. After the locking is completed, the protective cover 11 can be installed again as needed to ensure the overall closure of the device.

[0039] All the standard parts used in the present utility model can be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.

In addition, the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.
