I need help in understanding this one particular monostable multivibrator circuit.

I have gone through a lot of readings about monostable multivibrator and I understood how it works.
The only difference between all the readings that I had done with this particular monostable multivibrator circuit is the trigger.

The monostable multivibrator circuit, that I have no problem understanding it, has its trigger at the base of Q1.
But the monostable multivibrator that I had shown above has its trigger at the collector of Q1.

The problem is I can't visualize how the circuit work when the trigger is at the collector of Q1.

If you have any article that I can read about this, please share it.

Thank you in advanced!
