In the US, a fairly common but vulgar equivalent is "get your thumb out of your ass." Here's a discussion of its use by Steven King: https://forum.wordreference.com/threads/get-your-thumb-out-of-your-ass.1905486/
I think this is a really vulgar English expression which I would never use.
This a very crude, outdated and extremely sexist comment since it is an admonition to a man to take his finger out of a womans ❤❤❤❤ and get on with putting his penis in there.

Noone's quite sure where the expression came from, and honestly that's an interpretation I've never heard before. This website seems to think it's related to "pulling out all the stops":
