[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0023] Embodiment 1: As Figures 1-4 shown, the technical solution adopted by the present utility model is as follows: A medicine bottle opening device with a replaceable grinding wheel, including a first pliers body and a second pliers body, which are cross-hinged, presenting a scissor shape as a whole. The first pliers body is fixedly connected by a first pliers handle 1 and a first pliers head 3, and the second pliers body is fixedly connected by a second pliers handle 2 and a second pliers head 4.

[0024] The first pliers head 3 and the second pliers head 4 are arranged facing each other, and the facing ends of both are arc-shaped, facilitating the clamping of the medicine bottle. A through groove 6 is opened in the first pliers head 3 and runs through from front to back. A grinding wheel 7 is limited and clamped in the through groove 6. A card slot 8 is opened in the grinding wheel 7 and runs through from front to back. The card slot 8 is specifically a serrated slot.

[0025] An adjusting block 12 is fixedly arranged on the outer surface of the first pliers head 3, and a chute is opened in the adjusting block 12. A square rod 10 is limited and slidably arranged in the chute. One end of the square rod 10 slidably penetrates through the end of the adjusting block 12 away from the first pliers head 3 and a fixed block 11 is fixedly arranged. The other end of the square rod 10 is fixedly provided with a card block 9. The end of the card block 9 away from the square rod 10 slidably penetrates into the through groove 6 and is in limit clamping cooperation with the card slot 8 on the grinding wheel 7. A limit groove 14 is opened on the side of the first pliers head 3 away from the adjusting block 12, and the card block 9 passes through the card slot 8 and is inserted into the limit groove 14 for cooperation.

[0026] Both the card slot 8 and the limit groove 14 are adapted to the card block 9. The square rod 10 can slide along the groove direction of the card slot 8 in the card slot 8, facilitating the adjustment of the position of the grinding wheel 7.

[0027] An elastic resetting member is installed on the square rod 10, and the elastic resetting member includes a spring 13. The spring 13 is sleeved on the outer surface of the square rod 10 located in the limiting cavity. One end of the spring 13 is fixedly connected to the adjusting block 12, and the other end is fixedly connected to the clamping block 9.

[0028] Working principle of Embodiment 1: When an ampoule bottle needs to be opened, first place the ampoule bottle between the first clamping head 3 and the second clamping head 4. Secondly, the operator holds the first clamping handle 1 and the second clamping handle 2, closes the first clamping head 3 and the second clamping head 4, so that the grinding wheel 7 and the soft brush 5 are closely attached to the bottle mouth of the ampoule bottle.

[0029] Subsequently, rotate the ampoule bottle. During the rotation process, the grinding wheel 7 will rub against the bottle mouth of the ampoule bottle, making friction marks appear on the bottle mouth of the ampoule bottle. After the friction is completed, hold the first clamping handle 1 and the second clamping handle 2 tightly and gently break the bottle head of the ampoule bottle to open the ampoule bottle.

[0030] When the grinding wheel 7 needs to be replaced, pull the fixing block 11 to slide it in a direction away from the adjusting block 12. The sliding of the fixing block 11 will drive the clamping block 9 to slide synchronously through the square rod 10, so as to drive the clamping block 9 to disengage from the limiting groove 14 and the clamping groove 8 in sequence, thereby releasing the limit of the clamping block 9 on the grinding wheel 7, and then remove the old grinding wheel 7. During this process, the compression deformation amount of the spring 13 gradually increases.

[0031] After the old grinding wheel 7 is removed, insert a new grinding wheel 7 into the through groove 6, and control the clamping groove 8 on the new grinding wheel 7 to be aligned with the limiting groove 14. Then loosen the fixing block 11. At this time, under the elastic action of the spring 13, the clamping block 9 re-passes through the clamping groove 8 and is clamped in the limiting groove 14 to complete the replacement of the grinding wheel 7.

[0032] When the position of the grinding wheel 7 needs to be adjusted, push the fixing block 11 to slide it in a direction close to the adjusting block 12. The sliding of the fixing block 11 will drive the clamping block 9 to slide synchronously through the square rod 10. During the sliding process of the clamping block 9, it will disengage from the clamping groove 8, thereby releasing the limit of the clamping block 9 on the grinding wheel 7. When the clamping block 9 disengages from the clamping groove 8 but does not disengage from the limiting groove 14, at this time the square rod 10 is located in the clamping groove 8. Since the square rod 10 is in sliding fit with the clamping groove 8, the operator only needs to slide the grinding wheel 7 to adjust the position of the grinding wheel 7.

[0033] After the position of the grinding wheel 7 is adjusted, the operator loosens the fixing block 11. At this time, under the elastic action of the spring 13, the clamping block 9 re-enters the clamping groove 8 and the limiting groove 14, thereby completing the limiting clamping of the grinding wheel 7.

[0034] Embodiment 2: As Figures 1-4 shown, the difference between this Embodiment 2 and Embodiment 1 is that it can be used to open a medicine bottle with a cap, and the tops of the opposite ends of the first clamping head 3 and the second clamping head 4 are both pointed.

[0035] Working principle of the second embodiment: When the medicine bottle cap needs to be opened, the medicine bottle cap is first placed between the first clamp head 3 and the second clamp head 4. The operator holds the first clamp handle 1 and the second clamp handle 2, closes the first clamp head 3 and the second clamp head 4, clamps the side wall of the bottle cap of the medicine bottle, opens it, and pries it outward to remove it.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
