It is a kind of to fish the supporting bar structure of frame to improve with what,The braced bar system include a body of rod,One articulated part,One inserted link,An at least fixing element and a holder are constituted,Its characteristic is in what: the body of rod system is integrally formed made and is in hollow form,Pivot end and once pivot end are respectively provided on one at the body of rod both ends,On this pivot end system for the articulated part be placed in and a bolt of arranging in pairs or groups wear what on this pivot end one of preset that pivot hole is interior and articulated part in linked fixation,The lower pivot end system be placed in for the inserted link again and an at least fixing element of arranging in pairs or groups wears and gives screw lock in at least lockhole that the what lower pivot end is preset and be forced tight and fixed at the inserted link and be in the state stretched,Thereby,So that angler can arbitrarily adjust the whole height of the support rod and effect convenient for collecting.一種用於釣架之支撐桿結構改良，該支撐桿係包含一桿體、一樞接件、一插桿、至少一固定元件及一承置座所構成，其特徵在於：該桿體係為一體成型所製成且呈中空狀，該桿體兩端處各設有一上樞接端及一下樞接端，該上樞接端係供該樞接件置入並搭配一插銷穿設於該上樞接端所預設之一樞孔內及樞接件內予以連結固定，又該下樞接端係供該插桿置入並搭配該至少一固定元件穿設於該下樞接端所預設之至少一鎖孔內予以螺鎖且逼緊固定該插桿處而呈伸縮之狀態，藉此，以供釣者可任意調整該支撐桿之整體高度且方便收納之效果。
