The specific assembly process of the support assembly 2 is as follows:

the two first connecting members 21 are first mounted on one of the first support plates 20, the two second connecting members 22 are then mounted on the other first support plate 20, and then the two first support plates 20 are slidably mounted together.

The specific dismantling process of the support assembly 2 is as follows:

the two first connecting pieces 21 and one first supporting plate 20 are taken as a whole and pushed backwards to be detached; or the two second connecting pieces 22 and one of the first supporting plates 20 are pushed forward to be detached as a whole.

It is worth mentioning that, as can be seen from the process of removing the support element 2, when the first connecting member 21 and the second connecting member 22 move towards each other, the support element 2 can be removed, and the locking element blocks the first connecting member 21 and the second connecting member 22 from moving towards each other, i.e. when the entire storage shelf is built, the locking element is used to connect the partition board 1 with the first connecting member 21 or the second connecting member 22, and also has a decisive effect on the stability of the entire support element 2.
