.....Saved By The Bell.....

Aside from the late 1980s TV show namesake, which covered the lives of a small group of students attending fictional Bayside High School, this idiom is often is often said when a boxer suddenly revives from a knockout punch and is able to get up before the bell rings.

Or, it's likely said by students when the recess bell rings to go home, preventing anymore last minute assignments or testing to be dealt with, especially if they're anxious to go hang out with friends after school.

Or,,,,it might be said by anyone who might not wanted to have responded to an email or text and suddenly something occurs which prevents them from having to take immediate action, hence they are saved by the 'bell'.
