[0029] The two groups of second pressing plates 9 are fixedly mounted on the lower ends of the middle parts of the outer surfaces of both sides of the first pressing plate 7, and the handle 10 is fixedly mounted on the middle part of the outer surface of the upper end of the first pressing plate 7; the first pressing plate 7 and the second pressing plate 9 are both located at the upper part of the inner cavity of the solvent rack 2, and the first pressing plate 7 and the second pressing plate 9 are both pressed on the outer surface of the upper end of the sponge pad 3; the mounting groove 11 is opened on the outer surfaces of both ends of the first pressing plate 7, and the compression spring 12 and the guide rod 15 are both located in the mounting groove 11; the outer surface of one end of the guide rod 15 is fixedly connected to the middle part of one end of the mounting groove 11, and the compression spring 12 is movably sleeved on the outer wall of the guide rod 15, and the compression spring 12 is movably sleeved on the outer wall of the guide rod 15. The outer surface of one end of the compression spring 12 is fixedly connected to one end of the mounting groove 11, and the outer surface of the other end of the compression spring 12 is fixedly connected to the outer surface of one end of the clamping block 13. The guide groove 14 is opened in the middle of the outer surface of one end of the clamping block 13, and one end of the guide rod 15 extends into the guide groove 14; the outer wall of one end of the clamping block 13 is clamped with the clamping hole 6, and the outer wall of the clamping block 13 is slidably connected to the mounting groove 11. The outer surface of one end of the clamping block 13 is elastically connected to one end of the mounting groove 11 through the compression spring 12, and the clamping block 13 is slidably connected to the outer wall of the guide rod 15 through the guide groove 14.

[0030] The chromatograph 1 of the present invention is a kind of detection device of sodium acetate content in sodium acetate solution, and the liquid chromatograph 1 recorded in the article belongs to the prior art, and can be effectively known to the technicians in the relevant technical field, and the specific details are not repeated here; the sponge pad 3 and the limiting groove 4 are provided, and the sponge pad 3 is placed inside the solvent rack 2, and the bottom of the solvent bottle is inserted into the limiting groove 4. The provided sponge pad 3 can protect the solvent bottle, avoid collision between solvent bottles, and ensure the stability of the solvent bottle after placement; because the sponge pad 3 needs to be replaced after aging after use for a period of time, the sponge pad 3 is directly placed inside the solvent rack 2 and limited by the pressing structure 5.

Then, the pressing structure 5 can be pulled out upward by holding the handle 10, so that the sponge pad 3 can be replaced. After the pressing structure 5 is disassembled, the sponge pad 3 can be replaced, and it is easy to install. During installation, the clamping block 13 is squeezed so that the clamping block 13 enters the installation groove 11 to squeeze the compression spring 12, and then the first pressing plate 7 and the second pressing plate 9 are pressed on the upper outer surface of the sponge pad 3. When the clamping block 13 reaches the position of the clamping hole 6, the reaction force of the compression spring 12 drives one end of the clamping block 13 to be clamped into the clamping hole 6, thereby realizing the installation of the pressing structure 5 and facilitating operation.
