Conflicting points trouble the slowcoach (5)

I believe the answer is:
snail
'slowcoach' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'conflicting points trouble' is the wordplay.
'conflicting points' becomes 'sn' (two compass points. I am not sure about the 'conflicting' bit.).
'trouble' becomes 'ail' (synonyms).
'sn'+'ail'='SNAIL'
'the' acts as a link.
Can you help me to learn more?
(Other definitions for snail that I've seen before include "trailer" , "Slow slithery animal" , "Slow-moving creature" , "Common garden mollusc" , "10 ac mollusc" .)
