Abstract
Abstract A metal racket includes a shock removing member, a frame and a handle. The shock removing member has a fitting hole for a lower end of the frame having two shaft rods to fit through and into a hollow interior of the handle and fixed therein by rivets passing through rivet holes of the handle, the shock removing member and the shaft rods. Thus a shock reducing hollow space is formed between the lower end of the shock removing member and the lower end of the handle, When the racket receives shock in hitting a ball, the shock is firstly buffered by the shock removing member and then reduced by the shock reducing hollow space again.
