Abstract

An adjustable sports instrument comprises a rod body and a plurality of balance weights. Each balance weight is provided with a groove with the width smaller than the diameter of the rod body, a holewith large aperture is formed on each balance weight and communicated with the groove, the aperture of each hole is slightly larger than the diameter of the groove but equal to or slightly smaller than the diameter of the rod body, one end of the rod body is equipped with external thread, a neck portion and a nut, the diameter of the neck portion is equal to or slightly smaller than that of the groove of each balance weight, the neck portion can be embedded into the groove and the hole of each balance weight, the nut is in screw connection with the thread of the rod body and can be abutted against each balance weight, and then each balance weight can be penetrated or locked on the rod body quickly and conveniently. Besides, two ends of the rod body can be respectively equipped with external thread and a neck portion so as to form a dumbbell or a weight lift, or only one end of the rod body is equipped with external thread and a neck portion so as to form a kettle bell. The adjustable sports instrument has the advantages that the balance weights can be replaced or adjusted rapidly and conveniently.
