After moving to the appropriate position, the first electric telescopic rod 62 is activated, which causes the connecting plate 63 to drive the second rectangular frame 64 to move, so that the centrifuge tube is located between the two clamping arc plates 68. At this time, the two second electric telescopic rods 65 are activated, which causes the two clamping arc plates 68 to move towards each other, thereby assisting in clamping the centrifuge tube. At this time, under the action of the robotic arm structure 5, the centrifuge tube is positioned below the needle 78. Previously, the syringe 77 was snapped into the fixed frame 710. The second threaded extrusion rod 711 is rotated to fix the syringe 77. At this time, the circular block on the push rod 76 is snapped into the circular frame 74. The first threaded extrusion rod 75 is rotated to fix the push rod 76. At this time, the third electric telescopic rod 73 is activated, which drives the push rod 76 to move and extract. When cleaning is required, the fourth electric telescopic rod 712 is activated, so that the protective frame 715 is located below the needle 78. At this time, the fifth electric telescopic rod 714 is activated, which can move the protective frame 715 to directly below the needle 78. Then, the fourth electric telescopic rod 712 is controlled to move the protective frame 715 up and down, which can drive the bristles 716 to assist in cleaning the needle 78. At the same time, the needle 78 is protected when not in use. After the centrifuge tubes are used up, the mechanical arm structure 5 moves the centrifuge tubes above the placement slot 86. Then, the clamping and transfer structure 6 moves the centrifuge tubes into the placement slot 86. The centrifuge tubes are then released to complete the placement. After the threaded clamp 89 is separated from the first screw hole 87 and the second screw hole 88, the collection frame 85 is pulled upwards to separate the rectangular clamp 84 from the rectangular clamp frame 83, allowing the collection frame 85 to be disassembled.
