When the polygonal connecting rod 300 rotates to a certain angle, the polygonal connecting rod 300 can be matched with the jack 500 on the reagent pack, at this time, the second stop block 220 shields the light of the second light irradiated on the second optocoupler 210, the second optocoupler 210 cannot receive the light, and the rotation angle of the motor is a preset angle. Similarly, when the polygonal connecting rod 300 is at a certain angle, the polygonal connecting rod 300 cannot be matched with the jack 500 on the reagent pack, at this time, the second stop block 220 cannot block the second light to irradiate on the second optocoupler 210, the second optocoupler 210 receives the light, the second optocoupler 210 sends an electrical signal to the control circuit for informing that the current motor rotation angle is not a preset angle, the control circuit drives the motor to rotate, and the motor drives the polygonal connecting rod 300 to rotate, so that the motor rotates to the preset angle, namely: the polygonal link 300 is rotated to an angle that mates with the receptacle 500 on the reagent pack.

The polygonal link 300 is inserted into the insertion hole 500 in the reagent pack through the first mounting hole 410 of the mounting plate 400, and the other end is connected with the motor driving, so that the peristaltic pump in the reagent pack can be driven to operate. When the first inductive switch 100 senses that the reagent pack is not installed, an electric signal is sent to the control circuit for informing the installation state of the reagent pack, at this time, the control circuit controls the motor to rotate, and after the motor rotates to a preset angle, the motor is stopped to rotate, so that the angle of the polygonal connecting rod 300 is matched with the angle of the reagent pack jack 500. Thus, in this embodiment, when the first sensor switch 100 detects that the reagent pack is not mounted, the control circuit will control the motor to rotate to a preset angle such that the angle of the polygonal link 300 matches the angle of the reagent pack receptacle 500 regardless of the angle of the polygonal link.

Therefore, when the first inductive switch 100 senses that the reagent pack is not installed, an electrical signal is sent to the control circuit, and then the control circuit sends an electrical signal to the second inductive switch 200, so that the second inductive switch 200 detects whether the motor rotation angle is a preset angle, if the motor rotation angle is not the preset angle, that is, the angle of the polygonal connecting rod 300 is not matched with the angle of the reagent pack jack 500, the motor needs to be driven to rotate, so that the motor drives the polygonal connecting rod 300 to rotate to be matched with the angle of the reagent pack jack 500, and if the motor rotation angle is the preset angle, that is, the angle of the polygonal connecting rod 300 is matched with the angle of the reagent pack jack 500, the operation of the driving motor is stopped.
