Summary: | The utility model relates to a lock for multi-stage engineering management. A pull is linked with an outer lock cylinder through a clutch mechanism; the lock shell and the outer lock container are matched through marble assemblies, each marble assembly comprises a marble reset spring, a flat bead and a marble, and the lock for multistage engineering management further comprises N engineering keys divided into N stages. The N engineering keys need to be sequentially started from the first-level engineering key to the Nth-level engineering key, and after the next-level engineering key is started, the previous-level engineering key loses efficacy; at least N-1 groups of marble assemblies in the plurality of groups of marble assemblies further comprise engineering balls arranged between the flat beads and the marbles, and N-1 engineering balls form N-1 levels of engineering balls; except the first-stage engineering key, the other engineering keys are all provided with engineering ball grooves capable of taking th |
