Then, pull out the damaged seedling crushing blade and insert the new seedling crushing blade into the gap between the stop bar and the snap. After releasing the snap, the spring rebounds, driving the stop bar to re-lock into the buckle groove, completing the replacement. This allows for tool-free, quick blade disassembly and assembly, significantly shortening maintenance time.
