摘要： A shock-absorbing device is applied in a ball/racket frame having a plurality of string holes allowing a string to pass, and includes: at least one or more outer tubular member, disposed at a periphery of the ball/racket frame and arranged between the string holes adjacently disposed, wherein two sides and an outer side of the outer tubular member are formed with an adhering surface and an outer tubular wall, and a bottom end of thereof is formed with an adhering part adhered at the periphery of the ball/racket frame; and an inner tubular member, disposed in the outer tubular member along an axial direction and an inner side thereof is formed with an inner tubular wall; accordingly, by providing interferences at different timings and bearing shock waves of a counter shock force generated while a ball being struck via the string, effects of absorbing shock and damping are achieved.

摘要： A device capable of generating superposed shock waves, which is applied in a racket having a racket frame and having a racket string with warp strings and weft strings mutually woven to compose a string bed, and includes: at least one first main body formed as a hard medium, a lateral wall member is convexly formed at one side or two sides thereof, a first string slot having an opening at a top end is formed at an inner side of the lateral wall member or the center of the two lateral wall members, a recess is formed at the bottom end of the first string slot; and at least one soft medium, disposed in the first string slot and allowing the racket string to be fastened. As such, the shock wave can be returned for being backwardly transferred to increase the striking force for a ball member.
