Then, insert the core rod 9 into the guide tube 8, and make sure the limiting ring 10 is against the lower part of the guide tube 8. Next, fix the cover 7 on the upper opening of the core shell 1 by screwing, and finally, fix the handle 11 on the top of the core rod 9 by screwing. During the assembly process, make sure that each part is firmly installed, and the rotating protrusion 14 and the rotating limiting shell 5 are well matched to ensure the stability of the crushing column 12 during rotation.

[0048] The pharmaceutical crushing device has the advantages of high efficiency and crushing. The design of the crushing column 12 and the core shell 1 allows the drug to be fully squeezed and ground between them. The diameter of the crushing column 12 decreases linearly from top to bottom, and the distance between the outer wall of the crushing column 12 and the inner wall of the core shell 1 decreases linearly from top to bottom, which increases the pressure on the drug during crushing, ensuring high efficiency of crushing. The auxiliary friction lines 13 on the outer wall of the crushing column 12 and the core friction lines 2 on the inner wall of the core shell 1 interact with each other, increasing the friction between the drug and the device, further improving the crushing efficiency.

[0049] The device has the advantages of convenient operation and simple structure, which is easy to operate. The user can add the drug by holding the core shell 1 and rotating the handle 11 clockwise, without complicated operation process. Even non-professionals can easily operate the device. The position and size of the drug feeding port 4 are designed reasonably, which is convenient for adding the drug.

After use, the device can be easily disassembled into parts for cleaning, which effectively prevents cross contamination between different drugs, ensuring the quality and safety of the drug. The cleaned parts are easy to assemble, which is convenient for next use. At the same time, the detachable design is also convenient for maintenance and repair of the device, which prolongs the service life of the device.

[0051] The device has the advantages of stability. The rotating protrusion 14 at the lower part of the crushing column 12 is embedded in the limiting shell 5 in the middle of the lower wall of the core shell 1, which ensures the stability of the rotating crushing column 12, avoids shaking or deviation during crushing, and ensures the consistency of the crushing effect. The limiting ring 10 in the middle of the core rod 9 is against the lower part of the guide tube 8, which maintains the stability of the core rod 9 and avoids its upward movement, further improving the overall stability of the device.

[0052] The L-shaped placing frame body 15 of the outer wall of the core shell 1 is convenient for placing the device, space is saved, and the practicability of the device is improved.
