This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 杔 is uncertain. It combines 木 (tree/wood) with 乇, but the original semantic or phonetic role of 乇 in this character is unclear.
With 木 on the left and 乇 on the right, 杔 looks like a tree with a strange attachment. Since its meaning is unclear, picture a mysterious wooden object you cannot identify.
For タク, imagine a tack stuck into the mysterious wooden 杔: tack -> タク, and the tack is the only clue to its purpose.
