[0002] Traumatic diseases such as fractures and bone cracks caused by external force trauma to the lower limbs of the human body are common diseases in orthopedics. As the framework for supporting the human body, bones are the basis for ensuring mobility and play a crucial role in people's normal daily activities. Once the bones are damaged, people's normal activities will be directly restricted, and the recovery period of bones is long. In the later stage of the treatment process, rehabilitation nursing training is often required through auxiliary devices such as lower limb training and rehabilitation.

[0003] Existing lower limb rehabilitation devices generally use the method of kicking and stepping on pedals for recovery. For example, the "Lower Limb Fracture Postoperative Leg Rehabilitation Exercise Device" disclosed in the patent publication number CN218686042U and the "Lower Limb Rehabilitation Exerciser for Rehabilitation Department Nursing" disclosed in the patent publication number CN220938970U both carry out rehabilitation exercises by stepping on pedals. However, in the early stage of lower limb rehabilitation training, due to muscle atrophy in the patient's lower limbs and lack of strength in the legs, it is easy to cause secondary injuries due to excessive training during the kicking and stepping training, which affects the recovery. It is necessary to first stretch and recover the lower limb function. Content of the Utility Model
