[0021] Working principle: When in use, the blood to be tested is placed in the reagent tube 15, and the reagent tube 15 is placed in the placement slot 14 on the top of the workbench host 11 in turn, and the first servo motor 303, the second servo motor 308 and the electric push rod 9 are started, which can drive the movement of the detection needle 10, and the detection needle 10 is moved to the top of the reagent tube 15, and slowly inserted into the blood in the reagent tube 15 under the action of the electric push rod 9, so that the blood in the reagent tube 15 can be tested, and the detection needle 10 transmits the data to the workbench host 11, and the workbench host 11 analyzes the data and finally displays the test results on the display screen 16; After the detection needle 10 completes a blood test, the first servo motor 303, the second servo motor 308 and the electric push rod 9 drive the detection needle 10 to move, so that the detection needle 10 enters the flushing pool 1301, and the nozzle 1303 is started. The detection needle 10 is cleaned by the nozzle 1303 to wash away the residual blood on the detection needle 10. After the cleaning is completed, the detection needle 10 is driven by the electric push rod 9 to rise to the same height as the wiper plate 1305, and the cylinder 1304 is started. The output end of the cylinder 1304 drives the wiper plate 1305 to move toward the detection needle 10 and wipes off the residual water on the detection needle 10. During the drying process, the detection needle 10 can be driven up and down by the electric push rod 9, thereby improving the drying efficiency of the detection needle 10. After being wiped dry, the detection needle 10 can start to detect the blood in the next reagent tube 15; After all blood tests are completed, the dustproof sleeve 1204 is put on the detection needle 10 from bottom to top, and the positioning blocks 1203 on both sides of the top of the detection needle 10 are pressed to make it shrink into the inside of the mounting hole 1201 and compress the positioning spring 1202. During the installation process, when the positioning holes 1205 on both sides of the dustproof sleeve 1204 correspond to the positions of the positioning blocks 1203, under the elastic force of the positioning spring 1202, the positioning blocks 1203 are correspondingly connected with the positioning holes 1205, thereby completing the installation of the dustproof sleeve 1204. When removing the dustproof sleeve 1204, the positioning blocks 1203 on both sides of the dustproof sleeve 1204 are pressed in the same way to shrink it into the mounting hole 1201, thereby disconnecting the connection between the positioning blocks 1203 and the positioning holes 1205, and the dustproof sleeve 1204 can be removed by pulling it downward.
