How come the garage door is not opening and closing? - garage door clipart

There are actually pull a lever and open the garage door when you press the garage door. Then there is an iron bar along the chain (long) engine (box) and a garage door to the metal bar that opens and closes to get the garage. This metal bar is running short if the button is pressed the garage door in the chain, but it is exciting, and should, therefore, the door is not opened and closed. Someone has a solution for this problem? I would be delighted if the proposal is correct. Thank you.
