[0054] Then, the compression block 208 extrudes the supporting spring 209 under the action of the buckle cover 301, so that the air in the compression control cavity 204 can be transported to the driving air cavity 205 along the air hole on the limiting partition plate 203 under the action of the compression block 208, and the air in the compression control cavity 204 is transported to the driving air cavity 205, so that the positioning top block 206 is ejected under the action of air pressure, thereby clamping and positioning the microfluidic chip placed in the chip loading slot by the positioning top block 206. After loading is completed, the microfluidic chip can be observed and detected by the detection camera 103 by buckling the upper cover 102.
