This creation is to close a kind of flexible fishing rod of modified form of what, it includes plural number section rod body, each section rod body is the hollow body of point diameter shape smaller and tapered than Hou end diameter, Hou is chimeric before each section rod body is grouped into flexible fishing rod, it includes a plurality of annular recess that, which respectively saves rod body Hou end outer surface, each annular recess is formed as gas chamber, make the chimeric group connecting part position of each section rod body can be reduced hard contact area, it can thereby allow the sliding of each section rod body more smoothly, to reduce flexible fishing rod spoilage, reach the practical effect to prolong the service life.本創作是關於一種改良型伸縮釣竿，其包括複數節竿體，各節竿體為前端直徑比後端直徑小而呈錐形狀的空心管體，各節竿體前後嵌合組接成伸縮釣竿，於各節竿體後端外表面包括複數個環狀凹槽，各環狀凹槽形成如氣室一般，使各節竿體的嵌合組接部位能減少硬質接觸面積，藉此可讓各節竿體的滑動更為順暢，以減少伸縮釣竿損壞率，達到延長使用壽命之實用功效。
