Plastic Shaft and Assembly of components:
The plastic shaft with the assembly of gears, numbered disks and spring forms the most crucial part of the locking machinery. The combination of shaft, gears and numbered disk combine to form the following casing as shown in picture below:
When the assembly on the plastic shaft is dismantled, following components are attained. We can see disks, white colored plastic gears and a spring. A spring followed by couple of white colored plastic gears on which the numbered disks are adjusted is placed on the plastic frame.
The plastic shaft is the most crucial part of the assembly. The entire mechanism of activating and deactivating the lock revolves around this structure. The plastic shaft is similar to the key. It is circular in shape and has teeth like protrudes on its surface. A hollow rectangular frame is present at top which helps in placing the hooks near each other. Also it prevents slipping of the hooks in the vertical direction when force is applied. Total number of teeth pairs on the shaft corresponds to the number of disks used in the lock. In this case, since a three disk lock has been demonstrated, three pairs of teeth are present.
