[0021] Example

[0022] refer to Figures 1 to 5 The portable ampoule cutting device described in this embodiment includes a grinding wheel body 1. One end of the grinding wheel body 1 is fixedly connected to a mounting base 2. The other end of the mounting base 2 has a mounting groove 6. A handle 7 is movably connected inside the mounting groove 6. One end of the handle 7 is symmetrically fixedly connected to a positioning block 10. A positioning component 12 is installed inside the positioning block 10. One end of the grinding wheel body 1 has a through hole 19 that passes through the mounting base 2 and the handle 7. A fixing rope 17 is installed inside the through hole 19. One end of the fixing rope 17 is fixedly connected to a plug 18. The other end of the fixing rope 17 is knotted. The handle 7 is inserted into the mounting groove 6 of the mounting base 2 at one end of the grinding wheel body 1. Then, one end of the fixing rope 17 enters through the through hole 19 at one end of the grinding wheel body 1 and exits through the through hole 19 at one end of the handle 7. The fixing rope 17 is then knotted to complete the assembly of the handle 7 and the grinding wheel body 1.

[0023] refer to Figures 1 to 5A first rotating ring 3 and a second rotating ring 20 are respectively fitted on the outer side of the mounting base 2. The second rotating ring 20 is slidably connected to the mounting base 2. A first fixing frame 4 is fixedly connected to the outer wall of the first rotating ring 3. A second fixing frame 24 is slidably connected to the other end of the first fixing frame 4. A placement base 5 is fixedly connected to one end of the second fixing frame 24. Limiting tubes 21 are symmetrically fixedly connected to the upper end of the first rotating ring 3. A first return spring 23 is fixedly connected to the bottom end of the inner part of the limiting tube 21. A limiting post 22 is fixedly connected to the other end of the first return spring 23. The limiting post 22 is slidably connected to the inner part of the limiting tube 21. The other end of the limiting post 22 is fixedly connected to the bottom end of the second rotating ring 20. One end of the ampoule is inserted into the second fixing frame 24. Place the ampoule inside the base 5 and simultaneously push the second fixing frame 24, causing the second fixing frame 24 to slide inside the first fixing frame 4, so that the outer wall of the ampoule is in contact with the grinding wheel body 1. Then push the ampoule upward. The ampoule passes through the first fixing frame 4 and the second fixing frame 24, causing the first rotating ring 3 to move closer to the second rotating ring 20. The limiting post 22 slides inside the limiting tube 21, and the first return spring 23 is compressed, so that the cutting part of the ampoule is in contact with the grinding wheel body 1. Turn the handle 7, and the handle 7 drives the mounting base 2 and the grinding wheel body 1 to rotate. Because of the action of the first rotating ring 3 and the second rotating ring 20, the ampoule remains stationary. The grinding wheel body 1 cuts the ampoule. Finally, the ampoule can be bent.

[0024] refer to Figure 4 The positioning component 12 includes an internal hole 121, a second return spring 122, and a positioning post 123. The positioning block 10 has internal holes 121 symmetrically formed at both ends. One end of the internal hole 121 is fixedly connected to the second return spring 122, and the other end of the second return spring 122 is fixedly connected to the positioning post 123. The positioning post 123 is slidably connected to the internal hole 121. The end of the positioning post 123 extending away from the second return spring 122 extends to the side of the positioning block 10 and is arc-shaped. The mounting groove 6 has symmetrically formed positioning grooves 11 at one end. The positioning grooves 11 are inserted into the positioning block 10. The positioning grooves 11 have symmetrically formed positioning posts at both ends. Hole 13, positioning hole 13 and positioning post 123 are snap-fitted. When the handle 7 is inserted into the mounting groove 6 of the mounting seat 2 at one end of the grinding wheel body 1, the positioning block 10 is inserted into the positioning groove 11. During the insertion process, the squeezing force applies pressure to the arc-shaped end of the positioning post 123, causing the positioning post 123 to press against the second return spring 122. The second return spring 122 is compressed, and at the same time, the positioning post 123 retracts into the inner hole 121. Then, when the positioning post 123 moves to the positioning hole 13, the second return spring 122 returns to its original position, and the positioning post 123 pops out and snaps into the positioning hole 13 to fix it, thus completing the positioning of the handle 7 during installation.

[0025] refer to Figure 3The outer wall of the handle 7 is symmetrically fixedly connected to the limiting block 8 through a ring-shaped array. The inner wall of the mounting groove 6 is symmetrically opened with the limiting groove 9 through a ring-shaped array. The limiting block 8 and the limiting groove 9 are inserted into each other. When the handle 7 is inserted into the mounting groove 6 of the mounting seat 2 at one end of the grinding wheel body 1, the limiting block 8 and the limiting groove 9 are simultaneously inserted into each other.

[0026] refer to Figure 3 A non-slip pad 16 is symmetrically and movably connected to the outer side of the handle 7. A magnetic block 14 is fixedly connected to one end of the non-slip pad 16 near the handle 7. A magnetic groove 15 is symmetrically opened on the outer side wall of the handle 7. The magnetic block 14 and the magnetic groove 15 are magnetically connected. The non-slip pad 16 is attached to the handle 7 so that the magnetic block 14 and the magnetic groove 15 are magnetically connected, thus completing the installation of the non-slip pad 16.

[0027] refer to Figure 3 The anti-slip pad 16 has anti-slip texture on its surface and is made of soft rubber. The anti-slip pad 16 increases the friction between the handle 7 and the user's hand, thereby preventing the handle 7 from slipping due to wet hands or excessive force during use.

[0028] Operating principle and advantages: First, insert the handle 7 into the mounting groove 6 of the mounting base 2 at one end of the grinding wheel body 1. Simultaneously, the limiting block 8 engages with the limiting groove 9, and the positioning block 10 is inserted into the positioning groove 11. During insertion, the squeezing force applies pressure to the arc-shaped end of the positioning post 123, causing it to press against the second return spring 122. The second return spring 122 is compressed, and the positioning post 123 retracts into the internal hole 121. Then, when the positioning post 123 moves to the positioning hole 13, the second return spring 122 returns to its original position, and the positioning post 123 pops out and engages with the positioning hole 13, completing the positioning of the handle 7 during installation. Then, one end of the fixing rope 17 enters through the through hole 19 at one end of the grinding wheel body 1 and exits through the through hole 19 at one end of the handle 7. Tie a knot to complete the assembly of the handle 7 and the grinding wheel body 1. Insert one end of the ampoule into the placement seat 5 at one end of the second fixing frame 24. At the same time, push the second fixing frame 24 to slide inside the first fixing frame 4, so that the outer wall of the ampoule and the grinding wheel body 1 are in contact with each other. Then push the ampoule upward. The ampoule passes through the first fixing frame 4 and the second fixing frame 24, which drives the first rotating ring 3 to approach the second rotating ring 20. The limiting post 22 slides inside the limiting tube 21. The first return spring 23 is compressed, so that the cutting part of the ampoule is in contact with the grinding wheel body 1. Turn the handle 7. The handle 7 drives the mounting seat 2 and the grinding wheel body 1 to rotate. Because of the action of the first rotating ring 3 and the second rotating ring 20, the ampoule remains stationary. The grinding wheel body 1 cuts the ampoule. Finally, bend the ampoule.

[0029] This invention allows medical personnel to cut ampoules without directly contacting the grinding wheel or the neck of the ampoule, thus reducing the risk of hand injuries. It is also ergonomic, allowing medical personnel to apply force evenly and avoiding ampoule breakage or flying fragments due to improper force.
