Abstract:
An air bag buffer device for a hand tool, an air bag buffer device being installed the handles of the hand tool, the air bag buffer device comprising a hollow bag and a plug, whereinthe hollow bag is made of soft and elastic materials, such as rubber or plastics, a front end thereof is a hollow and sealed snake-like tube, at a center of one end of the snake-like tube is formed with a round post, a center of the round post has an axial helical hole, the helical hole is communicated with an interior of the snake-like tube;the plug is made of soft and elastic materials, such as rubber or plastics, the plug is formed as a helical post, a center of which is an axial air hole, a front end of the air hole formed with a unidirectional elastic valve piece which is closed in the front end;wherein, a front end of the plug is screwedly inserted into the helical hole of the round post of the hollow bag so that the elastic valve piece of a front end of the plug is exactly positioned in the snake-like tube of the hollow bag, therefore, an air bag buffer device with damping effect is formed; the buffer device is firmly secured to one handle or two handles of a hand tool so that impact from closing two handles are reduced to resist the separation of the two handles.
