Then, the lifting rod 5 is pulled to adjust the height of the cross plate 6 so that the sampling tube 14 can be extended into the solution undergoing a chemical reaction to perform sampling operations. After adjustment, the fastening knob 4 is turned in the opposite direction so that the rod part of the fastening knob 4 is in close contact with the lifting rod 5, and the adjusted lifting rod 5 can be limited and fixed.
