Call for help on collapsing in the stand (9)
I believe the answer is:
telephone
'call' is the definition.
('telephone' can be a synonym of 'call')
'help on collapsing in the stand' is the wordplay.
'collapsing' is an anagram indicator.
'in the' indicates putting letters inside.
'stand' becomes 'tee' (I've seen this before**).
'help'+'on'='helpon'
'helpon' with letters rearranged gives 'lephon'.
'lephon' placed inside 'tee' is 'TELEPHONE'.
'for' is the link.
(Other definitions for telephone that I've seen before include "Electronic sound equipment" , "Transmitter of spoken words" , "Electronic voice transmitter" , "Transmitter of speech, and now text and pictures" , "Mobile, for instance" .)
