This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
鞱 combines 革 (leather) with 舀, which likely contributes the sound. The exact historical development is uncertain, but it is probably a phono-semantic compound related to leather objects.
The left side 革 suggests leather, and the right side 舀 looks like a hand reaching into a container. Picture a leather pouch or bag being opened: the hand reaches in to wrap or store something.
For トウ, imagine a leather toe pouch: toe -> トウ, and the leather pouch wraps around the toe.
