Springy sort of stick! (4)
I believe the answer is:
pogo
'stick' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for pogo that I've seen before include "-- stick" , "punk dancing" , "gets jumped on by children" , "Punk movement" , "jump up and down" .)
