I've seen on tv, and in real life..they fire continously..like more than a bullet per second for few seconds untilk the clip is out...they obviously dont have some sort of battery...then how does the mechanism work?

The gas / force from the propelled cartridge forces the action back, removing the old cartridge. There is a spring to pull it back into place. Its the same principal as a semi-automatic weapon, except the firing pin falls forward with the bolt instead of cycling the trigger.
If a 160 grain bullet is firing at 1000 feet per second, that produces both forward and backward force from the point of explosion. The process just re-uses some of that energy to force the action backwards.

As each round fires, the expanding gas pushes back on a spring loaded mechanism that automatically ejects the spent cartridge, accepts the next round from the spring loaded clip, and displaces the firing pin to strike this new round.

It works by gases that are expelled when the round of ammunition is detonated; these gasses force the receiver or bolt open, ejecting the empty round and automatically (from the force of the receiver/bolt coming to a close) reloads the chamber with another round.
Semi- Automatic: Gun fires every time you pull the trigger w/o having to manually reload.
Fully Automatic: Gun fires repeatedly every time you pull the trigger, keeping trigger pulled back.

a 10 cent spring plus the gases from the pryer shot going off that also gives you the ejection of the cartrige
