A lifting threaded plate is threadedly connected to the outer side of the reciprocating screw. A bidirectional screw is rotatably connected inside the lifting threaded plate. Two threaded blocks are threadedly connected to the outer side of the bidirectional screw. Two connecting rods are fixedly connected to one side of the two threaded blocks and inside the lifting threaded plate. An arc-shaped clamping block is fixedly connected to one end of the two connecting rods and inside the lifting threaded plate.

[0009] The technical advantage of adopting the above-mentioned further solution is that it facilitates the clamping and fixing of the drug tube, while also allowing for adjustment of its height.

[0016] The beneficial effects of this utility model are as follows: This utility model has a novel structure, is simple to operate, and is easy to learn. It is not only compact in structure but also more practical. Compared with traditional devices, this utility model, by setting up a stepper motor, a hollow plate, a funnel tube, a titration groove rod, a disc, bolts, and threaded holes, can adjust the distance of the bolts installed at the center of the disc according to the needs of use. Thus, when the stepper motor rotates the hollow plate at a constant speed, the hollow plate drives the disc to different speeds through the bolts. By adjusting the position of the bolts, the inner diameter of the disc can be changed. When the bolts are too close to the center of the disc, the rotation speed is increased; when the bolts are too far from the center of the disc, the rotation speed is decreased. This allows for quantitative adjustment of different low-drop amounts, thereby avoiding excessive waste of resources and funds and providing convenience for operators. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4This utility model provides a technical solution: a titration device for quantitative drug analysis, including a base 1, a fixed support plate 2 fixedly connected to the top of the base 1, a support platform 5 fixedly connected to one side of the fixed support plate 2, a stepper motor 6 fixedly connected to the top of the support platform 5, a hollow plate 9 fixedly connected to the output end of the stepper motor 6, a funnel tube 4 fixedly connected to one side of the fixed support plate 2, a titration groove rod 7 rotatably connected inside the fixed support plate 2 and located inside the funnel tube 4, a disc 8 fixedly connected to one end of the titration groove rod 7, a bolt 10 threadedly connected inside the disc 8 and located inside the hollow plate 9, and a plurality of threaded holes 11 equidistantly opened on one side of the disc 8 to mate with the bolts 10. The device is equipped with a stepper motor 6. The device comprises a hollow plate 9, a funnel tube 4, a titration groove rod 7, a disc 8, bolts 10, and threaded holes 11. The distance at which the bolts 10 are installed at the center of the disc 8 can be adjusted according to usage needs. This allows the hollow plate 9 to rotate at a constant speed via the stepper motor 6, causing the disc 8 to rotate at different speeds through the bolts 10. By adjusting the position of the bolts 10, the inner diameter of the disc 8 can be changed. When the bolts 10 are too close to the center of the disc 8, the rotation speed increases; when the bolts 10 are too far from the center, the rotation speed decreases. This allows for quantitative adjustment of different low-drip dosages, avoiding excessive waste of resources and funds, and providing convenience for operators.

[0024] A scale line 12 is provided on one side of the hollow plate 9 to facilitate the adjustment of the inner diameter of the drive disc 8. Two fixing blocks 14 are fixedly connected to one side of the fixed support plate 2. A reciprocating screw 15 is rotatably connected inside the two fixing blocks 14. A lifting threaded plate 16 is threadedly connected to the outer side of the reciprocating screw 15. Two fixing blocks 14 are fixedly connected to one side of the fixed support plate 2. A reciprocating screw 15 is rotatably connected inside the two fixing blocks 14. A lifting threaded plate 16 is threadedly connected to the outer side of the reciprocating screw 15. A bidirectional screw 18 is rotatably connected inside the lifting threaded plate 16. Two threaded blocks 19 are threadedly connected to the outer side of the bidirectional screw 18. Two connecting rods 2 are fixedly connected to one side of the two threaded blocks 19 and inside the lifting threaded plate 16. 0. An arc-shaped clamping block 21 is fixedly connected to one end of the two connecting rods 20 and inside the lifting threaded plate 16, which facilitates clamping and fixing of the drug tube and adjusting the height position. The fixed support plate 2 has a limiting groove 17 that cooperates with the lifting threaded plate 16. A protective soft pad 22 is fixedly connected to the inner side of the arc-shaped clamping block 21. The limiting groove 17 can play a guiding and limiting role, and the protective soft pad 22 can play a protective role during clamping. Sealing rings 13 are fixedly connected to both sides of the funnel tube 4 and outside the titration groove rod 7 to prevent drug leakage. A control panel 3 is fixedly connected to the top of the base 1. The control panel 3 is electrically connected to the stepper motor 6 to facilitate the control of the overall operation of this utility model.

[0025] Specifically, during use, rotating the bidirectional lead screw 18 drives the two threaded blocks 19 closer to the lifting threaded plate 16, causing the lifting threaded plate 16 to move through the two connecting rods 20, thereby moving the arc-shaped clamping block 21. This, in turn, causes the protective soft pad 22 on the inner side of the arc-shaped clamping block 21 to clamp and fix the drug tube. When it is necessary to adjust the height of the lifting threaded plate 16, rotating the reciprocating lead screw 15 causes the lifting threaded plate 16 to slide and be limited within the limiting groove 17, thereby adjusting the distance between the lifting threaded plate 16 and the funnel tube 4. Then, when it is necessary to adjust the titration... During measurement, the bolt 10 is loosened by rotating it, and its position is adjusted by engaging with the threaded hole 11 inside the disc 8. When the bolt 10 is far from the center of the disc 8, the inner diameter of the disc 8 can be adjusted, thereby adjusting the driving speed. Then, the control panel 3 controls the stepper motor 6 to rotate the hollow plate 9. When the hollow plate 9 is rotated, it will drive the disc 8 to rotate through the bolt 10. When the disc 8 rotates, it will drive the titration groove rod 7 to rotate inside the fixed support plate 2, thereby causing the drug storage tank inside the titration groove rod 7 to be rotated, thus completing the titration work.
