Abstract
A hammer with shock-reduction structure includes an integrally formed hammer body and a handle cover. A rear section of the handle is formed with an H shaped rod for being engaged by the handle cover made of plastic or rubber. A plurality of front holes is installed on the lateral side of a front section of the H shaped rod and a plurality of rear holes is installed on the lateral side of a rear section of the H shaped rod. The number of the rear holes is larger than or equal to the number of front holes. A gap between the front holes and rear holes is larger than a gap between two adjacent holes. A tilt reduction portion is installed at the lower distal end of the H shaped rod. The H shaped rod at a rear section of the handle of the hammer is inserted into the handle cover which encloses the tilt reduction portion. A hollow space is formed between the opening and tilt reduction portion. The holes delete and dissipate the reacting force, and the space serves to hinder the transfer of the shock wave from the hammer to the user's hand.
