The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] like Figures 4 to 6 As shown, one embodiment of the present invention provides a sampling rod, which includes a main rod body 211 and a sampling head, wherein the sampling head is arranged on the main rod body 211, and the sampling head is used to contact with the object to be sampled for sampling. Among them, a positioning portion is arranged on the main rod body 211, and at least a part of the positioning portion is positioned and matched with the positioning structure of the part to be connected, so that the main rod body 211 is arranged on the part to be connected. Specifically, the part to be connected can be the main housing 10, and at least a part of the positioning portion is clamped on the positioning structure of the main housing 10. In this way, the transfer of the sampling rod can be completed by operating the main housing 10, thereby improving the hygiene of the operation.

[0045] By adopting the sampling rod provided in this embodiment, by providing a positioning portion on the main rod body 211, and making at least part of the positioning portion clamped on the positioning structure of the part to be connected, it is possible to facilitate the main rod body 211 to be set on the part to be connected. In this way, the staff does not need to directly operate the sampling rod, and can transfer the sampling rod through the part to be connected, thereby avoiding the possibility of direct contact between the sample on the sampling rod and the human body and the possibility of pathogen infection, improving the hygienic operation and facilitating the staff to operate better. Therefore, the sampling rod provided by the embodiment of the present invention can facilitate the operation of the staff and improve the convenience of operation.

[0046] In a specific embodiment, at least a portion of the positioning portion is snapped or plugged into a positioning structure of the component to be connected.

[0047] In a specific embodiment, the positioning portion includes a first positioning protrusion 214, and the first positioning protrusion 214 is used to be clamped in the first positioning groove 31 of the to-be-connected member, so as to position the sampling rod under the cooperation of the first positioning protrusion 214 and the first positioning groove 31. With such a setting, the sampling rod can be stably arranged on the to-be-connected member through the cooperation of the first positioning protrusion 214 and the first positioning groove 31, thereby improving the stability of the connection and preventing the sampling rod from being separated from the to-be-connected member during operation.

[0048] In a specific embodiment, the first positioning protrusion 214 is circumferentially arranged on the main rod body, and the first positioning protrusion 214 is used to be clamped in the first positioning groove 31 of the to-be-connected member, so as to axially position the sampling rod under the cooperation of the first positioning protrusion 214 and the first positioning groove 31. With such a setting, the axial positioning stability can be further improved through the cooperation of the circumferentially arranged first positioning protrusion 214 and the first positioning groove 31, so that the sampling rod can be stably arranged on the to-be-connected member better, and the stability of operation and connection is further improved.

[0049] In a specific embodiment, a snap-fit ​​structure is provided on the sampling rod, and the snap-fit ​​structure is used to snap-fit ​​with at least a portion of the sampling arm, so as to drive the sampling rod to move through the sampling arm. With such a configuration, it is convenient for the sampling arm to take away the sampling rod, so as to drive the sampling rod to sample through the sampling arm, thereby further improving the convenience of operation, improving the degree of automation of sampling, and reducing labor costs. The snap-fit ​​structure can be a structure such as a snap-fit ​​hook snap-fit, a snap-fit ​​hole snap-fit, etc.

[0050] In order to further improve the sampling stability, in a specific embodiment, the clamping structure is a clamping hole 217, and at least a portion of the sampling arm is clamped into the clamping hole 217 to drive the sampling rod to move.

A clamping protrusion 2173 is provided at the connection between the first hole 2171 and the second hole 2172, so that after the sampling arm passes through the first hole 2171 and enters the second hole 2172, the clamping member of the sampling arm is clamped with the clamping protrusion 2173. The clamping member here can be an elastic clamping member, and the elastic clamping member is clamped with the clamping protrusion 2173, which can further improve the stability of the clamping, so that the sampling arm and the sampling rod can be stably connected together, so as to better improve the stability of sampling.

[0052] In a specific embodiment, the sampling head includes a first sampling head 212, and the first sampling head 212 includes a liquid collection shell 2121. The liquid collection shell 2121 surrounds a liquid collection cavity, and a liquid collection port 2122 is provided on the liquid collection cavity, so that the sample to be sampled enters the liquid collection cavity through the liquid collection port 2122. With such a sampling arrangement, when the first sampling head 212 is extended into the sample to be sampled (the sample to be sampled here mainly refers to urine), the urine enters the liquid collection cavity through the liquid collection port 2122 to complete the sampling of urine.

[0053] In a specific embodiment, the sampling head includes a second sampling head 213, and the second sampling head 213 includes a sampling main rod 2131 and a sampling protrusion 2132.
