How do I get to the clipboard on my iPhone 7+?

iOS clipboard is an internal structure.

Access your clipboard pressing on any text app for a few seconds, then paste the clipboard's content. That content remains available until you overwrite it using the "copy" feature.

Would you be so kind to better explain your needs?

You can't "get to the clipboard".

To put something in the clipboard, highlight it and copy or cut.

To get something out, paste it into whatever you want.
