Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The features of the terms "first" and "second" in the specification and claims of the utility model may explicitly or implicitly include one or more of the features. In the description of the utility model, unless otherwise specified, the meaning of "plurality" is two or more.

The lead screw 14 is threadedly connected to the detection mechanism, and the first drive mechanism is used to drive the lead screw 14 to rotate. When the lead screw 14 rotates, it can drive the detection mechanism 20 to move along the extension direction of the length of the lead screw 14 to adjust the position of the detection mechanism 20. A pair of guide rails 31 are arranged vertically with the lead screw 14, the seat body 32 is arranged on the pair of guide rails 31, and can slide along the guide rails 31, the seat body 32 is provided with the detection mechanism 20, and the second drive mechanism is used to drive the detection mechanism 20 to slide along the guide rails 31.

[0027] Specifically, in this embodiment, assuming that the extension direction of the length of the lead screw 14 is the x-axis direction, the extension direction of the length of the guide rail 31 is the y-axis direction. The first driving mechanism is used to drive the lead screw 14 to rotate. The lead screw 14 is threadedly connected to the detection mechanism 20. When the lead screw 14 rotates, the detection mechanism 20 can move along the lead screw 14, so that the detection mechanism 20 moves along the x-axis direction. The seat body 32 is provided on a pair of guide rails 31 and can slide along the guide rails 31. The second driving mechanism is used to drive the seat body 32 to slide along the guide rails 31, thereby driving the detection mechanism 20 to slide along the guide rails 31, so that the detection mechanism 20 moves along the y-axis direction.

[0028] During testing, if Figure 3 As shown, the reagent strip 200 is inserted into the housing, and the reagent strip 200 is provided with a plurality of reagent strips, and the plurality of reagent strips are located between a pair of guide rails 31, and the detection mechanism 20 is located above the reagent strip. The first driving mechanism drives the detection mechanism 20 to move along the x-axis direction, and the detection mechanism 20 arrives at the starting position of the first reagent strip, and the second driving mechanism drives the seat body 32 to drive the detection mechanism 20 to slide along the guide rails 31, and the first reagent strip is collected for data. After the detection is completed, the second driving mechanism drives the seat body 32 to drive the detection mechanism 20 to return to the starting position. Then, the first driving mechanism drives the detection mechanism 20 to continue to move along the x-axis direction, arrives at the starting position of the second reagent strip, and the second driving mechanism drives the seat body 32 to drive the detection mechanism 20 to slide along the guide rails 31, and the second reagent strip is collected for data. After the detection is completed, the second driving mechanism drives the seat body 32 to drive the detection mechanism 20 to return to the starting position of the second reagent strip, and continues to repeat this action until all reagent strips are collected for data.
