摘要： A game racket and apparatus for adjusting the tension in the strings of a game racket. The game racket has a frame which forms a head. A handle is connected to the frame. The frame has a series of holes around its circumference. String or wire is laced through the holes of the frame to form a striking surface. The tensioning apparatus includes a screw which is threadedly mounted in the frame so that the string or wire passes over the head of the screw. The screw extends through the frame. The screw has engaging means exposed to the interior of the frame. The tension in the string is adjusted by turning the screw by means of the engaging means. The head of the screw may have shallow notches for releasably holding the string and for calibrating the adjustment of tension on the string.
