Spike obtains contraptions (7)

I believe the answer is:

gadgets

I'm a little stuck... Click here to teach me more about this clue!

'contraptions' is the definition.
('gadget' can be a synonym of 'contraption')

'spike obtains' is the wordplay.
'spike' becomes 'gad' (I am not sure about this - if you are sure you should believe this answer much more).
'obtains' becomes 'gets' ('get' can be a synonym of 'obtain').
'gad'+'gets'='GADGETS'

Can you help me to learn more?

(Other definitions for gadgets that I've seen before include "'Devices, gizmos (7)'" , "jimjams" , "Ingenious devices" .)

I've seen this clue in the Sydney Morning Herald.
