This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
摝 combines 扌 (hand) with 鹿 (deer). The exact historical development is uncertain, but it likely relates to a hand action associated with deer or a phonetic loan.
The hand radical 扌 beside a deer 鹿 suggests an action involving a deer, but the specific meaning is unclear.
For ロク, imagine a hand moving a deer-shaped lock: lock -> ロク, and the hand 扌 moves the deer 鹿.
