A sphincter stretching exercise feedback instrument for conveniently adjusting strength comprises a housing, a cover, an electromechanical assembly, and an electrical conduction device. The housing and the cover are stably connected, and the electromechanical assembly and the electrical conduction device are enclosed within the housing and the cover. The electrical conduction device comprises a plurality of conductive sheets and a center column. When any of the conductive sheets is contacted with the top of the center column, the electromechanical assembly will be triggered. The electrical conduction device is characterized in: the surface of the center column is configured with a plurality of convex protrusions, and the conductive sheets may proceed the leverage motion having the convex protrusions as support points. By rotating the center column, the conductive sheets may proceed the leverage motion corresponding to convex protrusions (support points) at different positions, and different support points may cause different leverage resistance values. Thus, the user may rotate the center column to train the sphincter and achieve the adjustment of resistance value.一種可便捷調整受力強弱之括約肌緊縮運動回饋儀,包括一外套、一外蓋、一機電總成及一導電裝置。該外套與該外蓋穩固相接,而該機電總成和該導電裝置被包覆在該外套和該外蓋內。該導電裝置含有複數根導電片及一根中心柱,當任一導電片觸碰中心柱的頂端便會觸動該機電總成。該導電裝置的特徵在於,該中心柱的表面設有複數個凸粒,而導電片以凸粒作為支點來進行槓桿運動。藉由轉動中心柱,可使導電片對應不同位置的凸粒(支點)來作槓桿運動,而不同的支點造成不同的槓桿阻抗值。因此,使用者可為訓練括約肌來轉動中心柱,來達成阻抗值得調變。10‧‧‧外套101‧‧‧套筒102‧‧‧凸緣2‧‧‧回饋儀20‧‧‧外蓋202‧‧‧旋鈕2021A、B‧‧‧控制鈕2022A、B‧‧‧發光單元2023‧‧‧無線啟動鈕
