Two positioning seats 11 corresponding one-to-one to the inserting rods 10 are fixed on the positioning ring 3. Slots are opened in the positioning seats 11, and the bottom parts of the two inserting rods 10 are respectively inserted into the corresponding slots. By pressing down the rotating column 6, the sliding column 9 on the rotating column 6 moves within the spiral groove 8, causing the rotating column 6 to drive the stirring rod 7 to rotate reciprocally along the direction of the spiral groove 8, thereby facilitating the stirring and mixing of the solution within the device. By inserting the two inserting rods 10 into the slots of the corresponding positioning seats 11, the installation of the top cover 4 is achieved, preventing the top cover 4 from rotating.

[0019] In one embodiment of the present application, preferably, a sample injection tube 12 is provided on the front side of the titration cell 1, and a sample outlet tube 13 is provided on the rear side of the titration cell 1. Removable sealing plugs are respectively provided within the sample injection tube 12 and the sample outlet tube 13. Sampling is carried out through the sample injection tube 12, and the sample is discharged through the sample outlet tube 13.

[0020] In one embodiment of the present application, preferably, the top of the rotating column 6 extends out of the fixed sleeve 5 and is rotatably connected to a pressure cap 14. By pressing down the pressure cap 14, the pressure cap 14 rotates relative to the rotating column 6.

[0021] In one embodiment of the present application, preferably, circular grooves are respectively opened on the left and right sides of the positioning ring 3. Rotatable cylinders 15 are provided within the circular grooves. One end of the two cylinders 15 extending out of the corresponding circular grooves is respectively fixed with a support rod 16.

After pressing down and then lifting the pressing cap 14 reciprocally, the pressing cap 14 rotates relative to the rotating column 6, and the sliding column 9 on the rotating column 6 moves in the spiral groove 8, so that the rotating column 6 drives the stirring rod 7 to rotate reciprocally along the direction of the spiral groove 8, thereby facilitating the stirring and mixing of the solution in the device. By inserting the two inserting rods 10 into the slots of the corresponding positioning seats 11, the concave rod 20 is inserted into the clamping groove under the action of the second spring, thereby further limiting and installing the top cover 4. The base 17 and the support rod 16 can facilitate the support of the titration cell 1, and the titration cell 1 and the support frame 2 can rotate along the cylinder 15, thereby facilitating the pouring of the sample from the sample outlet tube 13.
