An air bag buffer device for a hand tool comprises a hollow bag and a plug. The front end of the hollow bag is a hollow and sealed snake-like tube. At the center of one end of the snake-like tube is formed with a round post. The center of the round post has an axial helical hole, and the helical hole is communicated with the interior of the snake-like tube. The plug is formed as a helical post, the center of which is an axial air hole, the front end of the air hole formed with a unidirectional elastic valve piece which is closed in the front end. Thereby, the front end of the plug is screwedly inserted into the helical hole of the round post of the hollow bag so that the buffer device is firmly secured to one handle or two handles of a hand tool. As the hand tool applies a force, the impact from closing two handles are reduced to resist the opening of the two handles for being used again. |
