Abstract: A racket frame and protective packing device arrangement including an open racket frame which has a longitudinal recessed portion on an outside wall thereof, a plurality of string holes spaced on the recessed portion, and a plurality of elongated grooves connected between the string holes at an outer side; and a protective packing strip fitted into the longitudinal recessed portion which has a plurality of double open-end string tubes respectively inserted into the string holes for inserting a catgut string to set up a striking surface in the open racket frame, and a plurality of ribs longitudinally aligned and respectively fitted into the elongated grooves.

Abstract: A game racket frame has a head frame, a handle, and a connecting portion located between the head frame and the handle. The game racket frame comprises a segment between the front end of the head frame and the rear end of the connecting portion. With the exception of the line groove of the outer wall of the head frame, the segment has a rib plate of a predetermined length, which is arranged in the inner wall or the outer wall and is folded in a direction toward the opposite wall. The rib plate is connected with the top end or the bottom end of the head frame by a connecting plate. A folding line is constructed between the rib plate and the connecting plate. The game racket frame is therefore provided with an appropriate strength and a good ball-controlling capability.
