This creative department provides an adjustable massage ball, which is mainly composed of two massage balls and a connecting rod. The massage balls and the connecting rods are made of slightly elastic material. Each massage ball is provided with a set of inserts. Hole, so that the massage ball can be correspondingly inserted and combined with the two ends of the connecting rod to form a complete massage ball. The middle section of the connecting rod is provided with a large diameter slightly larger than the hole of the massage ball sleeve. Ring convex, and adjacent to the limit ring convex, equidistant from the two ends of the connecting rod with a plurality of positioning ring recesses, the width of the positioning ring recesses are roughly the same as the diameter of the massage ball sleeve socket hole edge. The thickness of the convex ring is the same, and its depth is consistent with the inner diameter of the locking convex ring of the massage ball sleeve socket. According to this, when the massage ball sleeve is inserted into the connecting rod, the locking convex ring of the massage ball sleeve socket must be passed through The positioning ring concave of the connecting rod achieves the positioning effect of the interlocking system, and is matched with its material characteristics, and the positioning ring concave of the positioning ring at different positions of the massage ball body and the connecting rod can be interlocked and positioned to give two massage balls Adjust the relative distance to meet the different needs of users.本創作係提供一種可調式按摩球，主要是由二按摩球體與一連結桿所組成，該等按摩球體與連結桿分別以略具彈性的材質製成，在各該按摩球體分別設有一套插孔，俾可將按摩球體呈相對應地套插結合於連結桿兩端而組成完整的按摩球，於該連結桿的中段乃設製有一大尺徑略大於按摩球體套插孔孔徑之限位環凸，且緊鄰著該限位環凸而朝連結桿兩端採等距製設有複數道定位環凹，該等定位環凹的寬度概與按摩球體套插孔孔緣的縮徑卡制凸環厚度相符，而其深度則與按摩球體套插孔的卡制凸環內徑相符，據以在將按摩球體套插結合於連結桿時，得透過按摩球體套插孔的卡制凸環與連結桿的定位環凹取得嵌結卡制的定位效果，並配合其材質特色，而可透過按摩球體的卡制凸環與連結桿不同位置之定位環凹嵌卡定位，進而賦予兩按摩球體相對距離之調整，以因應使用者的不同需求者。
