Morphology

two + shake + of + a + lamb's + tail

The image of 'two shakes' and a 'lamb's tail' evokes very brief, quick movements, so a learner who knows the words might guess the phrase refers to a short amount of time. However, the specific conventionalized meaning 'very quickly/in a moment' is idiomatic and culturally phrased, so the exact sense and idiomaticity are not fully predictable from the parts alone for a B1 learner.

Etymology

The idiom two shakes of a lamb's tail may come from a tiny, quick picture: a lamb giving its two shakes with its tail. Because those shakes are so brief, the phrase now means 'very quickly' or 'in a short time'.
