The utility model relates to an improvement of the fixed structure of the telescopic rod body of the areca collecting and retracting rod.The utility model is provided with a plurality of expansion joints with different diameters.The bottom hole diameter of the expansion joint is larger than the upper hole diameter.So that the expansion joints can be folded and stretched in order of diameter,At the top of the expansion pipe with the largest diameter, a plurality of embedded pipes with opposite arc segments are screwed.The snap parts are respectively arranged at the pre position of the inner surface of the relative arc segment.A plurality of clamped parts are arranged at the corresponding positions of the bottom pipe wall of the expansion joint of the second large pipe diameter and the snap parts of the arc segments.The expansion joint of the largest pipe diameter shall be positioned from the expansion joint of the second largest pipe diameter stretched internally.It can be fixed in the arc segments by the inlaid pipe pintle bundle.The clamping parts of the relative arc segments of the embedded tube and the bottom of the expansion joint of the second pipe diameter are clamped and positioned.In this way,In the expansion joint of the second pipe diameter and the largest pipe diameter,The outer pipe foundation is more stable and reliable in stretching and positioning, and it can prevent falling and shaking.一種檳榔採收桿之伸縮桿體固定結構改良，其係設複數不等管徑之伸縮接管，該等伸縮接管之底端孔徑較上端孔徑大，使其該等伸縮接管可依直徑大小依序容置收合及拉伸，於最大管徑之伸縮接管頂端螺接一具複數相對弧斷片之嵌合管，其中該嵌合管於相對之弧斷片內面預位處係分別設置有卡合部，該第二大管徑之伸縮接管底部管壁與該等弧斷片之卡合部相對應位置處設複數被卡合部，令該最大管徑之伸縮接管由內拉伸第二大管徑之伸縮接管定位上，可藉由該嵌合管樞套束固定位於該等弧斷片中，並令該嵌合管之相對弧斷片各卡合部與該第二大管徑之伸縮接管底部各被卡合部相卡置定位，藉此，達到該第二管徑之伸縮接管與最大管徑之伸縮接管內、外管基礎拉伸定位上更為穩固確實及防脫落晃動之目的。
