Figure 1As shown, the first lifting stroke is shown as H1 in the figure, and the second lifting stroke is shown as H2 in the figure. Corresponding to containers of different heights, especially when switching to containers of higher heights, the first lifting stroke can still be set to a smaller distance value, which can reduce the energy consumption of the lifting mechanism and improve the production efficiency of liquid infusion. Since the first lifting stroke can be set to a fixed value, the lifting mechanism can be set to a variety of forms such as a screw mechanism, a transmission belt mechanism, and a fixed-stroke cylinder, thereby improving the compatibility of the lifting mechanism.

The end of the mounting vertical pole 2 and the end of the first mounting cross bar 3 can be fixed by welding or the like. The moving paths of the first limiting device 11 and the second limiting device 12 enable the second lifting stroke to be adjusted, so that the lifting device can be applied to different production lines.
