[0009] As a preferred technical solution of the utility model, a placement block is fixedly connected to the upper end of the workbench, a placement groove is provided on the placement block, and a tube sleeve is provided inside the placement groove.

[0010] As a preferred technical solution of the utility model, support legs are fixedly connected to the top corners of the lower end of the workbench.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects: when the water quality detection rod is not needed, the annular tube can be pulled downward to separate the first magnet blocks on both sides of the annular tube from the second magnet block at the lower end of the horizontal plate. At the same time, the annular tube moves vertically downward, and the dustproof cloth changes from a wrinkled state to a straight state. The dustproof cap is then threadedly connected to the annular tube, so that the water quality detection rod can be placed in a closed space, thereby preventing air dust and impurities from adhering to the surface of the water quality detection rod and affecting the water quality detection results.
