Can openers belt cricket shots? (4-5)

I believe the answer is:

ring-pulls

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

'can openers' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'belt cricket shots?' is the wordplay.
'belt' becomes 'ring'.
'cricket shots?' becomes 'pulls' (I can't justify this - if you can you should give a lot more credence to this answer).
'ring'+'pulls'='RING-PULLS'

Can you help me to learn more?

(Another definition for ring-pulls that I've seen is " Pills rung (anag.)".)

I've seen this clue in The Times and The Sunday Times.
