Wheels turn handle used by writer (7)
I believe the answer is:
carroll
'handle used by writer' is the definition.
(Lewis Carroll, pen name of Charles Dodgson)
'wheels turn' is the wordplay.
'wheels' becomes 'car' (car wheel is a kind of wheel).
'turn' becomes 'roll' (roll is a kind of turn).
'car'+'roll'='CARROLL'
(Other definitions for carroll that I've seen before include "Lewis - - , 28 creator" , "See 17" , "Writer of nonsense" , "Lewis -- (Alice books)" , "Lewis -, Alice author" .)
