The invention provides a spinal-manipulating and bone-setting leg-shaking device. The spinal-manipulating and bone-setting leg-shaking device comprises a housing, a left ankle fixator, a right ankle fixator, an ankle swing power device, an ankle swing driving device and a controller. The spinal-manipulating and bone-setting leg-shaking device has the following beneficial effects: the device has asimple structure; left and right ankle joints of a patient are put on the left ankle fixator and the right ankle fixator; air bags on inner side walls of the left ankle fixator and the right ankle fixator are inflated with air; after the air bags are inflated with air, the air bags on left and right ankles expand and are closely matched with left and right ankles of the patient; a motor drives theleft ankle fixator and the right ankle fixator to shake leftwards and rightwards; the left ankle fixator and the right ankle fixator drive left and right legs of the patient to shake leftwards and rightwards; as a result, manual operation is replaced; and therefore, labor intensity of medical staff is greatly alleviated.
