The translation: The jack upper of emergency survival kit like it on car、英語翻訳、災害用ジャッキ

 How about having a disaster jack as a disaster prevention tool? 

Lift the rubble with a jack.

A jack is a thing that is loaded on a car and used for things like changing tires. It's a diamond-shaped piece of equipment. It is small, and like a vise, a small force can produce a large force. Even if your leg gets caught in the rubble, you might be able to get it out if you lift it up two centimeters with a jack.
