When the shaking and mixing is completed, the threaded rod 72 is rotated in the opposite direction by hand, so that the sealing plug 73 can be separated from the chemical test tube, and then The bolt 75 is unscrewed from the screw hole 74. At this time, the adjustment frame 71 and the test tube rack 6 are separated. Then the chemical test tube is removed from the test tube rack 6 for inspection. When the chemical test tube needs to be cleaned, it is reinserted into the placement slot 62, and then the electric push rod 85 is turned on to extend. At this time, the water pipe 84 and the nozzle 86 can be driven to move downward until the nozzle 86 moves into the chemical test tube. Then the water pump 82 is turned on. The water pump 82 can transport the water in the water tank 81 to the water pipe 84 through the hose 83, and finally spray it through the multiple groups of nozzles 86, so as to clean the multiple chemical test tubes. Compared with the traditional method, there is no need to manually clean one by one. It only needs to control the extension of the electric push rod 85 to move the multiple groups of nozzles 86 to the multiple groups of test tubes for flushing, which greatly improves the cleaning efficiency and facilitates the subsequent use of the test tubes.
