The utility model relates to a positioning bean structure, which is improved for the disadvantage that the conventional positioning bean is easy to move along the busbar when the pole is lifted or thrown.The new positioning bean system comprises an upper part and a lower part, wherein the upper part is longitudinally penetrated with an upper hole, the lower part is fixedly arranged under the upper part, and a lower hole matched with the upper hole is longitudinally penetrated, and at least a hollow area is defined between the upper hole and the lower hole, and the upper hole, the hollow area and the lower hole system can pass through the bus in sequence.Thus, when the new type of pole is lifted or thrown, the hollow area can be compressed to compress the hole diameter of the outer edge of the lower hole or the upper hole, so that the outer edge of the lower hole or the upper hole can clamp the bus bar, so as to buffer the force of the positioning bean when the pole is lifted or thrown, thereby improving the defect that the conventional positioning bean will move along the bus bar.一種定位豆結構，其係針對習用定位豆在起竿或抛竿時易沿母線位移之缺點而加以改良。本新型定位豆係包括有上部、下部構成；其中；上部縱向貫設有上孔；下部係固設於上部下方，且縱向貫設有一與上孔匹配之下孔，更在上孔與下孔之間至少界定有一中空區，該上孔、中空區、下孔係能依序供母線穿過。藉此，當本新型起竿或抛竿時，能透過壓縮中空區，用以壓迫下孔或上孔外端緣之孔徑，令下孔或上孔外端緣夾制母線，俾可緩衝定位豆在起竿或抛竿時之作用力，進而改善習用定位豆會沿母線位移之缺點。
