Abstract:
A shock-proof structure of a handle cover of a hand tool for improving the shock-proof ability of said handle cover, wherein said handle cover is made of soft elastic material and has a hollow handle shape; the center portion of said handle cover has an axial engaging hole for being engaged by an inserting portion of said hand tool; characterized in that:banks of vents are installed at sides of the upper and lower portions of said handle cover, each vent has a certain depth within said handle cover extending past a longitudinal axis of the engaging hole without passing through the handle cover, thereby, the vents are formed as air bags in the upper and lower portions of the handle cover and as a shock-proof structure of the handle cover; whereinwhen a react impact is induced from an object due to the hand tool, since a user's hand holds the vent openings, thus, the vents will be compressed and pinched so as to reduce a volume thereof, meanwhile, the react impact from said hand tool is buffered and the impact from said hand tool to said hand of said user is reduced.
