How I can constuct a vending machine by using mechanical power supply?

How the mechanical power can be produced for the power supply for a vending machine?

Too vague.
You can get help here, but like most other places no one is going to read your mind and give you what you want.

Older vending machines were entirely mechanical. Investigate those.
