[0036] In practical use: the outer diameter of the grinding wheel 14 is smaller than the opening diameter of the inner wall of the arc-shaped anti-splash ring 25, so that the grinding wheel 14 can move normally to the position of the ampoule opening, so that the opening device can operate normally.

[0037] In use, the ampoule is passed sequentially through the lower limiting sleeve 22 and the upper limiting sleeve 36. Several first rubber strips 24 and second rubber strips 38 on their surfaces press against the internal first elastic pad 23 and second elastic pad 37, limiting and fixing ampoules of different sizes. The pushing ring 110 drives the adjusting rod 13 to move within the through hole 19 on the surface of the fixing sleeve 12 and the fixing base 1. The adjusting rod 13 drives the grinding wheel 14 to move inside the arc-shaped splash guard 25 until the surface of the grinding wheel 14 is in contact with the opening of the ampoule. Holding the bottom of the ampoule, the adjusting rod 13, fixing sleeve 12, fixing base 1, and mounting frame 11 work together to rotate the grinding wheel 14, which in turn works with the lower limiting sleeve 22 and the upper limiting sleeve 36. The limiting sleeve 36 grinds the opening of the ampoule. After the grinding wheel 14 grinds the opening of the ampoule, it moves the upper limiting sleeve 36 in conjunction with the actuating block 39. The upper limiting sleeve 36, together with the connecting block 34, the locking nut 35 and the receiving ring 33, drives the bottom of the rotating rod 32 to rotate on the inner wall of the bearing 31. At the same time, the upper limiting sleeve 36, together with the second elastic pad 37 on the inner wall and several second rubber strips 38, performs a break-off operation on the upper part of the ampoule. During this process, the lower limiting sleeve 22, together with the arc-shaped anti-splash ring 25 on the top and the anti-splash cover 15 on the top of the mounting frame 11, can prevent the liquid inside the ampoule from splashing, thereby improving the opening efficiency of the opening device and reducing the risk of liquid splashing.
