[0032] The mechanical structure of the mobile multifunctional self-service testing device to which the multifunctional self-service testing device of the present invention is applicable is as follows: the device housing 1 integrates and mounts a display 2, a fixed barcode scanner 3, a main control box 4, a sample reagent rack 5, a pipette rack 9, a sampling table 10, a mixer 61, a testing machine 7, a main support 81, a main unit head 82, a main unit frame 83, a sample tube rotating electric gripper 101, a test tube rotating electric gripper 02 and an extraction tube rotating electric gripper 103, a material lifting electric cylinder, a material lifting electric gripper 85, an air pump lifting electric cylinder, an air pump 86, a QR code scanner 88 and an ID card information reader 80.

[0033] A four-axis mechanical structure is set inside the equipment housing 1: an X-axis drive mechanism, a Y-axis drive mechanism, a Z-axis drive mechanism, and a Y-axis drive mechanism for the loading slide. The X-axis drive circuit, Y-axis drive circuit, Z-axis drive circuit, and Y-axis drive circuit for the loading slide respectively drive and control the X-axis drive mechanism, Y-axis drive mechanism, Z-axis drive mechanism, and Y-axis drive mechanism for the loading slide to perform linear movement.

[0034] The X-axis drive mechanism drives the main support 81 to move horizontally along the X-axis at the top of the main control box. The Y-axis drive mechanism drives the main frame 83 to move horizontally along the Y-axis on the main support 81, thus achieving XY coordinate positioning.

An air pump 86 inserts and releases the pipette 91 to collect sample solution from the sample tube and add it to the detection tube, and to collect reagent solution from the reagent tube and add it to the detection tube. Thus, the pipette 91 sequentially aspirates the sample and reagents and adds them to the detection tube. A mixer 61 then agitates and mixes the liquid in the detection tube. A sensor 100 is installed at each positioning point to detect and confirm the accuracy and reliability of each action position.
