The test strip conveyor belt 100 is arranged on one side of the guiding mechanism 200. The CIS detector 300 is fixedly connected to the guiding mechanism 200 and is located at the top of the guiding mechanism 200. The sample dripping lever mechanism 400 is assembled on the side of the test strip conveyor belt 100 close to the test strip conveyor belt 100. The driving mechanism 500 is assembled on one side of the guiding mechanism 200. The test strip conveyor belt 100 includes a driving round pulley 101, a driven round pulley 102, a gear 103, a connecting frame 104, a conveyor belt body 105, a first bearing 106, a second bearing 107, a fixing plate 108 and a first fastening screw 109. The connecting frame 104 is slidably connected to the guiding mechanism 200 and is located on one side of the guiding mechanism 200. The first bearing 106 is rotatably connected to the connecting frame 104 and is located on one side of the connecting frame 104. The driving round pulley 101 is installed outside the first bearing 106. The second bearing 107 is rotatably connected to the connecting frame 104 and is located on the side of the connecting frame 104 away from the first bearing 106. The driven round pulley 102 is installed outside the second bearing 107. The conveyor belt body 105 is sleeved outside the driving round pulley 101 and the driven round pulley 102. The gear 103 is fixedly connected to the driving round pulley 101 and is located on one side of the driving round pulley 101.
