The other end of the holding member 200B is provided with a recess 230B recessed toward the connected portion, and the recess 230B is fitted to one end of the sampling part 1000.

Specifically, as shown in fig. 3, the sample collection device is further provided with a storage tube 1100 containing a sample preservation solution for storing the sampling component 1000 after sampling. The holding member 200B is configured to be fitted to the nozzle of the storage tube 1100, and after the sampling of the sampling unit 1000 is completed, the holding member 200B is detached from one end of the connection member 200A and placed together with the sampling unit 1000 into the storage tube 1100 containing the sample preservation solution. At this time, only the connection member 200A of the sample collection device is returned to the inside of the housing 100 along with the electric telescopic rod 310, as shown in fig. 2.

More specifically, the connecting part and the connected part can be connected by clamping, screwing or other detachable fixed connection modes. Preferably, in order to facilitate quick and repeated assembly and disassembly of the clamping member 200B and the connecting member 200A, the clamping connection is adopted in this embodiment.

More specifically, the clamping member 200B is made of a flexible material, such as rubber, foam, or other flexible material, so as to cover the nozzle of the storage tube 1100. The specific configuration may be set according to actual design and use requirements, and this embodiment does not specifically limit this.

The connecting member 200A and the holding member 200B are detachably connected by a connecting portion and a connected portion, and the sampling part 1000 is detachably connected to the holding member 200B by a recess 230B of the holding member 200B. With this arrangement, convenience in replacing the sampling member 1000 can be increased.

Furthermore, the housing 100 of the sample collecting device provided in this embodiment 2 is further provided with a partition plate 120, the peripheral side of the partition plate 120 is fixedly disposed on the inner side wall of the housing 100, and a storage space is formed between the partition plate 120 and the sealing cover 110. A hole is provided at the center of the partition plate 120, and a seal portion adapted to the inner wall surface of the hole is provided on the peripheral side of the clamping member 200B. When the mounting member 200 is in the initial position (as shown in fig. 6), the sealing portion on the peripheral side of the holding member 200B and the hole portion in the center of the partition plate 120 are closely fitted to each other. Further, a storage fluid storage portion 130 is disposed in the storage space, and the storage fluid storage portion 130 is disposed on the inner sidewall of the casing 100 and extends along the circumferential direction of the inner sidewall of the casing 100.

More specifically, the position state of the sampling member 1000 is the position of the sampling member 1000 relative to the housing 100. When the control module 600 determines that the protruding length of the sampling component 1000 relative to the housing 100 is equal to the length threshold, the reminding module 700 is controlled to emit a prompt sound, so that the detection personnel can prepare for being sampled. When the control module 600 controls the linear driving mechanism 300 to return to the initial position (as shown in fig. 9), the reminding module 700 is controlled to emit a reminding sound to remind the inspector that the sampling operation is completed.

It should be noted that the reminding module 700 can remind the position state of the sampling component 1000, so as to further improve the convenience of using the sample collecting device.

As shown in fig. 8, after the sampling of the sample collection device is completed, the holding member 200B can be detached and placed together with the sampling member 1000 into the storage tube 1100 containing the sample preservation solution, so that the situation that the sampling member 1000 after the sampling is completed is directly contacted by a hand of a detector is avoided, and the sampling accuracy of the sampling member 1000 is improved.
