The present invention is a patch having an expansion support effect, and is provided with a body, at least one first support member and at least one second support member. The body is provided with an adhesive surface and a joint surface, and the two support members are disposed on the body. And each of the supporting members is disposed along the longitudinal direction of the body and is provided with a fixing portion, an engaging portion and a movable portion, so that the two supporting members are arranged along the longitudinal direction of the body and arranged in a line The engaging portion of each supporting member can be engaged with the movable portion of the other supporting member, thereby providing the supporting strength required for the main body during the expansion process by the structural aspect of the engaging portion and the movable phase. In order to provide a patch that is compact in structure, easy to use, and has an expanding support effect.本新型係一種具擴張支撐效果之貼片，其設有一本體、至少一第一支撐件及至少一第二支撐件，該本體設置有一黏貼面及一結合面，該兩支撐件設於本體上且能相互活動配合設置，各支撐件沿著該本體的長度方向設置且設有一固定部、一卡合部及一活動部，使該兩支撐件沿著該本體的長度方向設置且呈直線排列，其中各支撐件的卡合部能與另一支撐件的活動部相卡設結合，進而通過卡合部與活動相卡設的結構態樣，提供該本體於擴張過程中所需的支撐強度，藉以提供一結構精簡、方便使用且具擴張支撐效果之貼片。
