When unlocking is required, the screw cap 55 is pulled off to make the card block 56 disengage from the limiting groove 42, and the screw cap 55 is rotated. The cam 53 on the connecting rod 52 disengages from the support of the locking blocks 542 on both sides. The locking blocks 542 are disengaged from the groove on the through slot 41 by the spring reset, and the lock of the storage cabinet 4 is released. At this point, the installation and disassembly of the storage cabinet 4 and the shell 1 are completed.
