Abstract: A clutch with high binding ability comprises a plurality of detent components provided between a left and a right lateral plates and each detent component can be pulled back to its original location by a resilient element. The detent block of each detent component is movably positioned between the left and the right lateral plates. The detent element of each detent component is slidably connected onto the detent block. One end of the detent element is provided with a groove for locating a positioning bar therein. Thereby, when the clutch rotates, the radial force of the detent element can be increased in order to enhance the detent ability of the detent element. When the rotational speed of the clutch is decreased to be the rotational speed of passive driving or to be lower than the rotational speed for engagement, the detent element can be pulled back to its original location by means of the elastic element located between the detent block and the detent element.
