[0013] This utility model has at least the following beneficial effects:

[0014] With an adjustable component, during use, turning the handle causes the path rod to rotate, which in turn drives the moving ring to move within the positioning rod. The moving ring then passes through a sliding groove in the positioning rod via a connecting block on its front side, causing the mounting block to move in front of the positioning rod, thereby adjusting the position of the extraction tube as needed.

[0015] The connecting rod is installed on the front side of the mounting block by means of a plug. Then, the positioning springs in the slots on the left and right sides of the plug move the positioning ball, so that the positioning ball is locked in the positioning slot opened in the mounting block slot, thereby fixing the position of the connecting rod and fixing the extraction tube.

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an extraction device for drug quality management, including a fixing plate 1.

[0023] A mounting rod 3 is provided on the rear side of the upper surface of the fixed plate 1, and an adjustment component is installed on the upper end of the mounting rod 3. A mounting block 8 is provided on the front side of the adjustment component, and a connecting rod 9 is provided on the front side of the mounting block 8. The front end of the connecting rod 9 is installed with the extraction tube 13. A piston rod 14 is movably inserted into the upper end of the extraction tube 13, and an extraction head 15 is installed at the lower end of the extraction tube 13.

[0024] Fixing bases 2 are provided at the four corners of the lower surface of the fixing plate 1, and rubber anti-slip blocks are provided at the lower ends of the four sets of fixing bases 2. The rubber anti-slip blocks can increase the friction between the device and the ground, thereby preventing the device from sliding or moving during use and ensuring the stability and accuracy of the extraction operation.

[0025] The adjustment assembly includes a positioning rod 4, a path rod 5 inside the positioning rod 4, a moving ring 6 outside the path rod 5, a connecting block on the front side of the moving ring 6, and a matching sliding groove on the front side of the positioning rod 4. The connecting block is connected to the rear side of the mounting block 8. The path rod 5 has a threaded structure on its outer side, and a matching threaded hole is opened inside the moving ring 6. A handle 7 is installed at the upper end of the path rod 5. By rotating the handle 7, the path rod 5 rotates inside the positioning rod 4. Then, through the engagement of the threaded structure on the outer side of the path rod 5 and the threaded hole in the moving ring 6, the moving ring 6 moves outside the path rod 5. Then, the connecting rod 9 on the front side of the moving ring 6 passes through the sliding groove opened in the positioning rod 4, driving the mounting block 8 to move.

[0026] A plug 10 is provided on the rear side of the connecting rod 9, and the plug 10 is designed with a T-shaped structure. A matching T-shaped slot is provided on the front side of the mounting block 8. The T-shaped structure design can provide better anti-torsion and anti-pull force, ensuring that the connection between the connecting rod 9 and the mounting block 8 is more stable and not easy to loosen or fall off.

[0027] The insert 10 has slots on both the left and right sides, and each slot is equipped with a positioning spring 11. The ends of the two sets of positioning springs 11 that are far apart are equipped with positioning balls 12. The slots of the mounting block 8 have matching positioning slots on both the left and right sides. The combination of positioning springs 11 and positioning balls 12 can provide additional locking force after the insert 10 is inserted into the slot, preventing the insert 10 from loosening or falling off due to vibration or external force during operation.

[0028] A scale is provided on the front side of the extraction tube 13. The scale can intuitively display the height or volume of the liquid or sample in the extraction tube 13, so that the operator can accurately control the amount extracted each time.

[0029] Working principle: The medicine is placed on the upper surface of the base plate, and the extraction tube 13 is installed on the mounting block 8 through the insertion block 10. The positioning spring 11 drives the positioning ball 12 to be locked on the mounting block 8. Then, the throttle 7 is turned, which drives the path rod 5 to move outside the path rod 5 through the threaded structure and the threaded hole in the moving ring 6. Then, the connecting block on the front side of the moving ring 6 passes through the positioning rod 4 to drive the extraction tube 13 to move, thereby driving the extraction tube 13 to be inserted into the medicine. Then, the piston rod 14 is pulled to extract the medicine.
