The inner shaft 42 is inserted into the rack rod 41 through a through hole, a locking screw shaft 44 is inserted into the top side of the rack rod 41 through a threaded hole, and the end of the locking screw shaft 44 is inserted into the inner shaft 42 through a groove.

The vertical cross section of the rack rod 41 is L-shaped. Rubber balls are symmetrically arranged on the outer side of the L-shaped vertical plate end of the rack rod 41 . The vertical plate end of the rack rod 41 is inserted into the docking frame plate 34 .

A fixing screw shaft 35 is inserted through a threaded hole on the outer side of the top end of the sleeve 33 , and the end of the fixing screw shaft 35 abuts against the surface of the column 31 .

The outer side of the ring plate 43 is butt-jointed with a restraining fitting 45 by bolts. The restraining fitting 45 comprises a side plate 451 . A threaded rotating shaft 452 is inserted through a threaded hole at the center of the outer side of the side plate 451 . The end of the threaded rotating shaft 452 is rotatably connected to a rubber pressure plate 453 .

A groove is formed at the top of the base 1, and a counterweight 5 is embedded in the groove.

Two restraining plates 25 are symmetrically arranged on the inner wall of the placement groove of the rotating disk 21, and a push rod 24 is connected to the outer side of the restraining plate 25, and a shifting block 23 is connected to the end of the push rod 24, and the shifting block 23 is embedded in the rotating disk 21 through a sliding groove.

By pulling the inner shaft 42 inside the through hole of the frame rod 41, the position of the ring plate 43 can be conveniently adjusted. When the inner shaft 42 is pulled out, the shaft end of the locking screw shaft 44 can be moved inside the threaded hole of the frame rod 41. The locking screw shaft 44 can be pressed against the inner wall of the groove of the inner shaft 42 to ensure the stability of the inner shaft 42 after the pulling and adjustment. The vertical plate end of the frame rod 41 is inserted into the slot of the docking frame plate 34, which can facilitate the suspension installation of the frame rod 41. At the same time, the rubber ball block on the outside of the frame rod 41 can be embedded in the groove of the inner wall of the slot of the docking frame plate 34 to ensure the docking stability of the frame rod 41 and the docking frame plate 34. The height of the ring plate 43 can be freely adjusted by moving the sleeve 33 up and down on the outside of the column 31. When the movement and adjustment of the sleeve 33 are completed, the sleeve can be fixed by the screw shaft 35. The threaded hole 33 moves inside and contacts the outside of the column 31, ensuring the stability of the sleeve 33 after adjustment. After the burette is inserted into the ring plate 43, it moves inside the threaded hole of the side plate 451 through the threaded shaft 452, and then pushes the rubber pressure plate 453, so that the rubber pressure plate 453 can contact the outside of the burette to ensure the stability of the burette installation.

Working principle: As shown in FIG. 5 , before use, the test cups containing different solutions are placed in the placement slot of the rotary disk 21. By moving the dial block 23, the dial block 23 can push the constraint plate 25 to move through the push rod 24, and then the constraint plate 25 abuts against the outside of the test cup to constrain the test cup. At the same time, when the test cup is placed in the placement slot of the rotary disk 21, the suction cup 22 can adsorb the test cup to ensure the stability of the placement of the test cup.

Secondly, as shown in Figures 2 and 3, the staff pushes the sleeve 33 to adjust the sleeve 33 to a suitable height. After the adjustment is completed, the sleeve 33 can be squeezed on the outside of the column 31 through the fixed screw shaft 35 to ensure the stability of the installation of the sleeve 33. At this time, the rod end of the frame rod 41 can be inserted into the docking frame plate 34 according to the use requirements to facilitate the installation of the frame rod 41. At this time, the burette can be inserted and placed inside the ring plate 43 and can be rotated and moved by the threaded rotary shaft 452. The movement of the threaded rotary shaft 452 can push the rubber pressure plate 453 to move, so that the rubber pressure plate 453 contacts the outside of the burette, ensuring the stability of the burette placement and facilitating the titration operation.
