[0034] When installing the blade base plate 20 on the connecting groove 10, first place the blade base plate 20 into the connecting groove 10, so that the blade 22 is located in the opening 11. Then, push the blade base plate 20 to move within the connecting groove 10, so that the locking strip 23 can be engaged with the protrusion 12. When removing the blade base plate 20 from the connecting groove 10, first push the blade base plate 20 away from the connecting groove 10, so that the locking strip 23 disengages from the protrusion 12. Then, remove the blade base plate 20. It can be understood that the installation and removal of the blade base plate 20 can be completed on the cover 1 without opening the cover 1. The installation and removal steps are simple and quick. Moreover, during the installation and removal process, the user does not need to directly contact the blade 22, which can reduce the risk of being scratched by the blade 22 and greatly improve the safety and convenience of use.

[0035] It should be noted that the blade base plate 20 and the bottom wall of the connecting groove 10 are positioned and engaged through a positioning structure. The positioning structure includes positioning protrusions and positioning grooves disposed opposite to each other on the blade base plate 20 and the connecting groove 10. The positioning protrusions can be moved into or out of the interior of the positioning grooves. Specifically, in this embodiment, the blade base plate 20 has a first positioning protrusion 31 and a first positioning groove 32 respectively provided at both ends on the side facing the positioning groove 10.

The shapes of the first positioning protrusion 31 and the second positioning groove 34 are adapted to each other and can be engaged in a concave-convex fit. The shapes of the second positioning protrusion 33 and the first positioning groove 32 are adapted to each other and can be engaged in a concave-convex fit.

[0036] In other embodiments, the opening of the connecting groove 10 can be formed on the inner surface of the cover 1, so the cover 1 must be opened before the blade base plate 20 can be disassembled or assembled. Other detachable connection structures can be provided between the connecting groove 10 and the blade base plate 20, such as an insertion structure or a magnetic attraction structure between the groove wall of the connecting groove 10 and the side wall of the blade base plate 20. In the positioning structure, the position, shape, and number of the paired positioning protrusions and positioning grooves can be adaptively adjusted according to design requirements.

[0037] In this embodiment, the cover 1 is also provided with a protective baffle 40. One end of the protective baffle 40 is detachably rotatably connected to the inner side of the cover 1, and the other end of the protective baffle 40 has a protruding plate 41 protruding outward from the middle. The protruding plate 41 is movably connected to the limiting structure of the fixing plate of the clamp 3. It can be understood that the end of the protective baffle 40 connected to the limiting structure is provided with a first receiving groove 42 and a second receiving groove 43, which are used to abut against the top holding block and the limiting block of the limiting structure, respectively, so that the protective baffle 40 can be stably connected to the fixing plate of the clamp 3. The protective baffle 40 is provided with a through hole 44 corresponding to the shape and position of the blade 22, through which the blade 22 can pass.

[0038] It should be noted that the protective baffle 40 can form a protective barrier between the blade 22 and the clamp 3 to further improve the safety of the medicine cutter. When the box cover 1 and the box body 2 are in the open state, the two ends of the protective baffle 40 can be rotated with the opening action of the box cover 1 to be inclined and supported on the inner side of the box cover 1 and the limiting structure, so as to prevent the blade 22 from being exposed on the box cover 1, so that the user is not easy to be cut by the blade 22 when performing the fixing operation of the medicine tablet, and the safety of use is ensured. When the box cover 1 and the box body 2 are in the closed state, the two ends of the protective baffle 40 can be rotated with the closing action of the box cover 1 to cover the clamp 3. Not only can it play a role in assisting the clamp 3 to fix the medicine tablet, but also the blade 22 can pass through the hole 44 to extend into the clamp 3, so as to achieve the purpose of dividing and cutting the medicine tablet in the clamp 3. In other embodiments, the box cover 1 can not be provided with the protective baffle 40, and the fixing plate of the clamp 3 can not be provided with the limiting structure.

[0039] The box body 2 is provided with a mounting seat. In the embodiment, the mounting seat includes a rotating shaft seat 51 located on the inner wall of the box body 2, two exposure holes 52 opened on the outer wall of the box body 2, and a plurality of first fixing columns 53 distributed on both sides of the fixing plate of the clamp 3. The rotating shaft seat 51 is used to rotatably connect the driving member of the clamp 3, the exposure hole 52 is used to expose at least part of the driving member on the box body 2, and the first fixing column 53 is used to detachably connect the fixing plate of the clamp 3 to the mounting seat. In other embodiments, the number and position of the exposure hole 52 in the mounting seat can be adjusted according to the different structures of the driving member in the clamp 3, and correspondingly, the mounting seat can not be provided with the exposure hole 52. The first fixing column 53 can be replaced by other structures for detachable connection with the fixing plate of the clamp 3, such as a sliding groove and sliding strip structure, a buckle structure, a magnetic fixing structure, a threaded fixing structure, a bolt fixing structure, etc.

[0040] It can be understood that in the embodiment, the inside of the box body 2 is provided with a receiving groove 60, and the box cover 1 is also provided with a receiving groove 60 at the corresponding position. When the box cover 1 and the box body 2 are in the closed state, the receiving grooves 60 in the box cover 1 and the box body 2 are connected to form a receiving space for receiving medicine tablets. At the same time, the receiving groove 60 of the box body 2 can be used alone as a receiving space for receiving medicine tablets. In other embodiments, the box body 2 can not be provided with the receiving groove 60, and the box cover 1 can not be provided with the receiving groove 60.

[0041] The clamp 3 comprises a fixed plate 70, a driving member 80 and a clamping member. In the embodiment, a second fixing column 71 is arranged on one side of the fixed plate 70 at a position corresponding to the first fixing column 53, and the second fixing column 71 is insertably connected with the first fixing column 53. Thus, the clamp as a whole can be conveniently disassembled and assembled on the mounting seat through the fixed plate 70. It can be understood that a sliding groove 72 for slidingly clamping the clamping member is formed on the fixed plate 70, one side wall of the fixed plate 70 forms a limiting groove 73, the limiting groove 73 comprises a plurality of branches corresponding to the sliding groove 72, and a part of the connecting structure of the clamping member is movably connected in the limiting groove 73. The sliding groove 72 and the limiting groove 73 are used to limit the connecting part of the clamping member to move only in the direction defined by the two grooves, so as to ensure the stability of the clamping member. In other embodiments, the second fixing column 71 can not be arranged on one side of the fixed plate 70, and the fixed plate 70 can be correspondingly arranged in a corresponding structure according to the dismountable mounting structure of the mounting seat.

[0042] A limiting structure is arranged on the other side wall of the fixed plate 70, and the limiting structure comprises two top holding blocks 74 arranged at one end of the fixed plate 70 and a limiting block 75 located between the two top holding blocks 74. It can be understood that the height of the top holding block 74 is greater than the height of the limiting block 75, and the limiting block 75 deviates from the connecting line of the two top holding blocks 74, so that the convex plate 41 can be inserted and rotatably connected between the limiting block 75 and the two top holding blocks 74. It can be understood that when the protective baffle 40 is in the inclined supporting state, the two top holding blocks 74 abut against the first accommodating groove 42. When the protective baffle 40 is in the collapsed covering state, the limiting block 75 abuts against the second accommodating groove 43. It should be noted that the limiting structure can improve the speed of mounting or dismounting the protective baffle 40 from the fixed plate 70 on the premise that the protective baffle 40 is rotatably connected to the fixed plate 70. When the protective baffle 40 needs to be dismounted, first dismount the one end of the protective baffle 40 from the box cover 1, and then pull out the protective baffle 40 from the limiting structure. When the protective baffle 40 needs to be connected between the box cover 1 and the fixed plate 70, the above steps can be operated in reverse, which is simple, labor-saving and fast.

[0043] In the embodiment, the driving member 80 is rotatably installed on the rotating shaft seat 51, and the driving member 80 comprises a gear 81 and a dial wheel 82 coaxially fixed.
