[0035] The outer casing 1 is equipped with a centering clamping and fixing mechanism 2 for centering and clamping ampoules of different sizes;
[0036] The outer casing 1 is equipped with an opening and suction mechanism 3 for opening and extracting liquid from ampoules with scratches.
[0037] The outer shell 1 is provided with a bottle mouth collection compartment 4 for collecting the opening of the upper bottle mouth of the ampoule;
[0038] The lower end of the outer shell 1 is fixedly installed with an ampoule recycling bin 5 for collecting ampoules after liquid extraction;

[0040] In this invention, the operator places the ampoule into the outer shell 1 using the clamping component 22, and then drives the clamping component 22 to center and fix the ampoule using the clamping drive component 21. Then, the opening and liquid aspiration mechanism 3 is activated to scratch and open the ampoule, and liquid is extracted after opening. After liquid extraction, the ampoules are collected uniformly. This invention achieves automatic clamping and fixing of ampoules of different sizes while simultaneously scratching, opening, and extracting liquid.
[0041] like Figure 3 As shown, the clamping drive assembly 21 includes an electric push rod 211, a wedge block 212, and a transmission block 213; the electric push rod 211 is fixedly connected to the rear inner wall of the housing 1, and the driving end of the electric push rod 211 is fixedly connected to the wedge block 212; the wedge block 212 is slidably connected to the rear inner wall of the housing 1; the wedge block 212 is slidably connected to the rear end of the transmission block 213, and the transmission block 213 is connected to the clamping assembly 22; the lower end of the transmission block 213 is slidably connected to the housing 1 in the front-back direction.
