发明名称 String attaching to game racket handle
摘要 A pin is connected between the two legs of the game racket frame in the handle portion near the end. This assembly is placed in a mold with an insert between the legs abutting the pin and initially effectively blocking any string from being looped around the pin and emerging through the bottom of the handle portion. Handle molding material is introduced into the mold to form the handle. The material around the pin is then routed out forming a channel open at the bottom of the handle portion for receiving the handle string that may be readily looped about the pin.
