Background

In related experiments involving microbial cultivation, it is often necessary to take pieces of bacteria of the same size and specific diameter from a long bacteria plate by a puncher and to connect the pieces to a fresh medium plate, and the operation process needs to ensure a sterile environment. At present, after the conventional puncher finishes punching holes, fungus cakes are not easy to separate from the puncher, and the fungus cakes are easy to break due to the fact that the fungus cakes are taken out of the puncher manually through materials such as toothpicks or needle heads in many cases; when various strains are inoculated, each strain is replaced, the puncher needs to be burned and disinfected by the alcohol lamp again until the puncher is cooled, and then the punching operation can be continuously repeated, so that the time and the labor are wasted, and the working efficiency is low; if the burned puncher is not cooled sufficiently, punching and bacterium cake taking operations are carried out when the temperature is high, so that the strain is easy to inactivate; if the burning and disinfection of the puncher are insufficient, strain pollution is easy to cause, so improvement is needed.
