The present invention relates to a device which expands the anal ballooning of the body, is made of a semi-circular symmetrical cross-section diameter of which is gradually reduced toward the front from the rear, respectively, of the rear end has a handle inclined to the opposite direction to each other formed a first and second semi-circular member of plastic material, so that the lower edge of the first semi-circular member and forming a predetermined interval in the longitudinal direction, and an actuate inside diameter is formed, a portion of the arc-shaped inner diameter portion is opened having a plurality of clamps, and a second semi-circular member of the plurality of projections formed along the longitudinal direction at intervals corresponding to the spacing between the clamps of the first semi-circular member along the lower edge to form an inlet, and between the protrusions arranged to connect and, is resiliently press-fitted on the inner diameter of each said circular-arc through an inlet of the clamp including a plurality of coupling rods of circular cross-section that is coupled to be rotatable, a plurality of clamps of the first semi-circular member by the coupling into a plurality of elastically fastening rod of the second semi-circular member provides an extension device to form a rotating anal shaft. According to the present invention, it enables the production costs of low-cost compared to conventional, and is simply discarded after a single use, and used for other patients, and it is possible to obtain an improved treatment effect can be used in the sanitary new products.COPYRIGHT KIPO 2015본 발명은 신체의 항문을 벌려서 확장시켜 주는 장치에 관한 것으로, 후방으로부터 전방으로 향하여 점차 직경이 축소되어지는 반원형 단면의 좌우 대칭형으로 이루어지고, 각각의 후방 단부에는 서로 반대쪽 방향으로 기울어진 손잡이가 형성된 플라스틱 재료의 제1 및 제2 반원형 부재를 구비하고, 제1 반원형 부재의 하부 모서리를 따라서 길이방향 일정 간격으로 형성되고, 내부에는 원호형 내경부가 형성되며, 상기 원호형 내경부의 일부분이 개방되어 유입구를 형성하는 다수의 클램프, 및 제2 반원형 부재의 하부 모서리를 따라서 상기 제1 반원형 부재의 클램프들 사이의 간격에 대응하는 간격으로 길이방향을 따라서 형성된 다수의 돌출부들을 구비하고, 상기 돌출
