[0027] Specifically, the optical coupler 14 is used to start up and detect the status position of the test paper conveyor rack, the infrared sensor light module 15 automatically senses the placed test strips and starts the detection step, the bearing 17, the pressing inner shaft 16, and the supporting inner shaft 15 are used to stabilize the operation of the transmission bracket 1, making the detection result more stable and reliable.
