[0039] Working principle: when in use, firstly, the first motor 200 drives the first rotating shaft 201 to rotate, and when the first rotating shaft 201 rotates, it rotates through the second rotating shaft 203. At this time, the lever 210 is located on the side close to the third cover plate 14. At this time, the second gear 208 is meshed with the fourth gear 213, so that when the second rotating shaft 203 rotates, the fourth gear 213 is driven to rotate through the second gear 208. When facing the third cover plate 14, the first rotating shaft 201 rotates right, and the first rotating shaft 201 rotates right, drives the fourth gear 213 to rotate counterclockwise through the second gear 208. When the fourth gear 213 rotates counterclockwise, the fourth gear 213 drives the second rack 215 to move to the left, that is, the second rack 215 drives the second moving block 25 to move to the outside of the device housing 1. When the second moving block 25 moves After the first moving block 20 moves out, the lever 210 is pushed toward the side of the first motor 200. At this time, the second gear 208 is separated from the fourth gear 213, and the first gear 207 is meshed with the third gear 212. At this time, the first gear 207 drives the first rack 214 to move left through the third gear 212. After the first moving block 20 moves out, the first motor 200 is stopped, and the test tube is inserted into the test tube slot 26, and the detection card is placed in the detection card slot 21. When the test tube is inserted, the outer surface of the test tube pushes the test tube fixing block 502 to compress the spring 501. The test tube fixing block 502 always clamps the test tube under the elastic action of the spring 501 and can clamp the test tube. Then the first rotating shaft 201 is reversed. At this time, the first moving block 20 is reset, and then the lever 210 is reset to the position close to the first rotating shaft 201. On one side of the third cover plate 14, the second moving block 25 is also reset and then the first motor 200 is stopped, the third cover plate 14 is opened, and the suction head 405 is inserted into the suction head mounting tube 404. At this time, the second slider 302 is located on the side of the first electric slide rail 300 close to the third cover plate 14, and the pipette body 403 is located directly above the test tube. The second mounting plate 303 is driven down by the second electric slide rail 301 until the suction head 405 is inserted into the liquid in the test tube. For the convenience of observation, the third cover plate 14 can be a transparent plastic plate, the solenoid valve 409 is closed, and negative pressure is generated by suction through the air pump 400, and the liquid is sucked into the suction head 405. By adjusting the second electric slide rail 301 and the first electric slide rail 300, the pipette body 403 is moved above the detection card slot 21, and the air pump 400 releases air to push out the liquid in the suction tip 405, so that it drips onto the detection card, and then the second mounting plate 303 is moved above the waste recovery box 8, the solenoid valve 409 is opened, the air pump 400 blows air, the suction tip mounting tube 404 extends out and pushes down the connecting sleeve 408, the end surface of the connecting sleeve 408 pushes the suction tip 405, and the suction tip 405 is pushed out from the suction tip mounting tube 404, and the suction tip 405 falls into the waste recovery box 8, and then the second mounting plate 303 is reset to the side close to the third cover plate 14, and the detection card below is detected through the detection module 28 on the first mounting plate 27. After the detection, the second motor 23 drives the fourth rotating shaft 24 to rotate toward the side of the waste recovery box 8, and the second motor 23 drives the reagent placement platform 22 to rotate toward the side of the waste recovery box 8.The detection card is then introduced into the waste recycling box 8 and reset, thus completing the entire multi-channel detection. The waste recycling box 8 is convenient for collecting disposable waste, and the waste recycling box 8 is conveniently extracted and cleaned through the recycling box slot 7.
