Can the patent dependent claim increase the part structure on the basis of sovereignty?

1, you can add some structures, mainly explaining the structural mode. Pay attention to protecting the content. If it is a core technical solution, put it in the sovereignty item.

2. The claim may not quote drawings and reference marks, and the specific marks may be described in the specification. In the reference number, only the used parts are marked. If the added part is described in the text, corresponding drawings and marks should be added.
