The other end of the connecting spring (32) is fixedly connected to the telescopic plate (33). The rectangular plate (21) is clamped at the lower end of the telescopic plate (33).

4. A blood cross-matching test instrument as claimed in claim 1, characterized in that: A plurality of button assemblies (5) are provided on the side of the thermostatic box (6) at the upper end of the sealed door (4), and a handle (3) is fixedly connected to the side of the sealed door (4) adjacent to the card plate (23).

5. A blood cross-matching test instrument as claimed in claim 1, characterized in that: The upper end of the device body (1) is located adjacent to the centrifuge housing (17) and is provided with a plurality of test tube racks (7). The upper end of the device body (1) is located adjacent to the centrifuge housing (17) and is provided with a plurality of button assemblies three (18).

6. A blood cross-matching test instrument as claimed in claim 1, characterized in that: The upper end of the device body (1) is located adjacent to the test tube rack (7) and is fixedly connected to an isolation plate (10), and the upper end of the device body (1) is located adjacent to the isolation plate (10) and is fixedly connected to a protective plate (8).

7. A blood cross-matching test instrument as claimed in claim 6, characterized in that: A rectangular mounting plate (11) is fixedly connected to the side surface of the protective plate (8), and a lighting lamp (12) is arranged at the lower end of the rectangular mounting plate (11).

8. A blood cross-matching test instrument as claimed in claim 1, characterized in that: A heating component (15) is arranged at the upper end of the device body (1) adjacent to the isolation plate (10), a heating chamber (14) is arranged at the upper end of the heating component (15), a plurality of placement grooves (13) are arranged inside the heating chamber (14), and a plurality of button components (16) are arranged on the side of the heating component (15).

9. A blood cross-matching test instrument as claimed in claim 1, characterized in that: A plurality of support pads (2) are fixedly connected to the lower end of the equipment body (1), a sealing cover (9) is rotatably connected to the upper end of the centrifuge housing (17), and an inner centrifuge assembly (19) is arranged inside the centrifuge assembly (20).

10. A cross-matching test instrument and blood matching method according to any one of claims 1 to 9, characterized in that: The steps include: Step 1: During the cross-matching operation, the staff collects the plasma raw materials that need to be cross-matched and places them on the upper placement plate (25), and then puts them into the constant temperature box (6) for constant temperature storage. Then, the pull-out sliding bottom plate (24) is used to facilitate quick access, thereby ensuring the quality of the plasma raw materials; Step 2: In the blood matching process, the plasma raw material is taken out from the thermostatic box (6), and then placed in the inner centrifuge assembly (19) provided inside the centrifuge assembly (20) for centrifugation, thereby separating the plasma raw material to facilitate the subsequent blood matching, and then the separated or unseparated plasma raw material is placed in the test tube rack (7) through the test tube for temporary storage; Step 3: After the centrifugation operation is completed, the staff will place the separated plasma raw materials into the placement tank (13), and then use the heating chamber (14) to facilitate the heating operation, ensure that the test tube is at a suitable temperature, and then facilitate the staff to add other operating materials to complete the cross-matching operation.
