[0012] Preferably, a spring is sleeved on the outer side of the guide rod, one end of the spring is connected to the inner wall of the mounting groove, and the other end of the spring is connected to the surface of the limit seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the drug inspection titration device can move the solvent bottle on the support plate up and down to a suitable position through the mutual cooperation of the threaded rod and the bevel gear group, so that the drug inspection titration device can accurately drip the reagent into the interior of the solvent bottle, and the friction between the solvent bottle and the support plate is increased by the anti-slip pad, so that the solvent bottle on the drug inspection titration device is placed more stably.

[0014] 1. The drug inspection titration device drips corresponding reagents through the titration device when inspecting drugs to achieve the purpose of determining the content of a certain specific component in the drug or determining the concentration of the solution. First, the solvent bottle is placed above the support plate, and then the connected bevel gear set and the threaded rod are driven to rotate synchronously by turning the knob. With the rotation of the threaded rod, the mounting seat can be driven to move up and down along the inside of the mounting cavity until the mounting seat drives the solvent bottle on the support plate to move synchronously to a suitable height. The reagent is dripped into the inside of the solvent bottle through the burette. The solvent bottle on the support plate can be moved up and down to a suitable position through the mutual cooperation of the threaded rod and the bevel gear set, so that the drug inspection titration device can accurately drip the reagent into the inside of the solvent bottle;

[0015] 2. The drug inspection titration device first pulls the two limit seats outward to the limit position at the same time. At this time, the distance between the two limit seats is the largest. The anti-skid pad is placed on the surface of the support plate, and then the two pulled limit seats are loosened. The loosened limit seats can automatically reset outward by the elastic force of the spring. The anti-skid pads should be mounted on both side surfaces of the anti-skid pads. The anti-skid pads made of rubber increase the friction between the solvent bottle and the support plate, making it difficult for the solvent bottle to slip when placed, thereby making the placement of the solvent bottle on the drug inspection titration device more stable.

[0023] The side plate 501 is provided with limiting grooves 503 on both sides of the inner wall near the installation cavity 502, and the interior of the installation cavity 502 is docked with a mounting seat 504, and the two sides of the mounting seat 504 are connected to limiting blocks 505; the limiting block 505 is docked inside the limiting groove 503, and a threaded rod 506 runs through the middle of the limiting block 505, and the two ends of the threaded rod 506 are connected to the inner side of the installation cavity 502 through the bearing seat; a bevel gear set 507 is sleeved and installed above the threaded rod 506, and the side plate 50 1 is installed with a knob 508 on the upper side, and the knob 508 is connected to the bevel gear set 507; the outer end of the mounting seat 504 is connected with a support plate 509, and a solvent bottle 6 is placed on the support plate 509, and the limit blocks 505 are symmetrically distributed about the center of the mounting seat 504, and the cross-sectional dimensions of the limit blocks 505 match the cross-sectional dimensions of the limit groove 503, and the limit blocks 505 and the limit groove 503 are slidably connected, and the mounting seat 504 and the threaded rod 506 are threadedly connected.

[0024] During the specific implementation, the solvent bottle 6 is first placed above the support plate 509, and then the connected bevel gear set 507 is driven to rotate synchronously by turning the knob 508, and the threaded rod 506 is driven to rotate synchronously under the rotation of the bevel gear set 507. Since the threaded rod 506 and the mounting seat 504 are threadedly connected, the mounting seat 504 can be driven to move up and down along the inside of the mounting cavity 502 with the rotation of the threaded rod 506. At this time, the moving mounting seat 504 is stably moved along the inside of the limiting groove 503 through the limit blocks 505 connected on both sides, until the mounting seat 504 drives the solvent bottle 6 on the support plate 509 to move synchronously to a suitable height, and the reagent is dripped into the inside of the solvent bottle 6 through the burette 4. The solvent bottle 6 on the support plate 509 can be moved up and down to a suitable position through the mutual cooperation of the threaded rod 506 and the bevel gear set 507, so that the drug inspection titration device can accurately drip the reagent into the inside of the solvent bottle 6.
