Specific embodiments

[0028] The utility model is further explained in combination with the drawings and specific embodiments, so that the person skilled in the art can better understand the utility model and can be implemented, but the embodiment is not as the limitation of the utility model.

[0029] Referring to Figures 1 to 3 The utility model discloses a kind of reagent needle assembly perpendicularity detection devices, for detecting the perpendicularity of reagent needle assembly 1.

[0030] The reagent needle assembly perpendicularity detection device includes frame body unit, and the frame body unit includes base 20 and support frame 21, and the support frame 21 is arranged on the base 20.

[0031] The reagent needle assembly verticality detection device further comprises a first detection unit, the first detection unit comprises a first support block 40 and a first boss assembly, the first support block 40 is detachably arranged on the base 20, the first support block 40 has a first mounting surface extending along a first direction, and the first boss assembly is arranged on the first mounting surface; the reagent needle assembly 1 is driven to move into contact with the first boss assembly to detect the verticality of the reagent needle assembly along the second direction.

[0033] It should be noted that the side surface of the first boss assembly in contact with the reagent needle assembly 1 is a vertical plane; and the side surface of the second boss assembly in contact with the reagent needle assembly 1 is a vertical plane.

Specifically, the reagent needle assembly 1 comprises a lifting assembly and a reagent needle 10, the reagent needle 10 is connected with the lifting assembly, and the reagent needle 10 can be driven to lift.

[0035] During detection, if the reagent needle assembly 1 can move to completely fit with the first boss assembly, it indicates that the reagent needle assembly 1 is vertical in the second direction; if the reagent needle assembly 1 can move to completely fit with the second boss assembly, it indicates that the reagent needle assembly 1 is vertical in the first direction.
