The calf muscle group squeezing module is used for squeezing the muscles of the posterior group and the lateral group of the patient's calf. The ankle joint movement mechanism is attached to the patient's foot and performs reciprocating movement in the direction parallel to the patient's Achilles tendon through the driving mechanism. The muscles of the posterior group and the lateral group of the patient's calf can be periodically squeezed, so that the patient's calf muscles, knee joints and ankle joints are passively exercised, the lower limb venous circulation of the patient is promoted, edema is reduced, the patient's pain is alleviated and relieved through massage, the patient's motion injury is prevented, and the patient's rehabilitation is facilitated.

However, the patient is helped to recover by a rehabilitation therapist, which is time-consuming and costly. Most of the existing lower limb rehabilitation training devices are for gait training and squatting training, and there is no targeted training device, which leads to the problem that it is inconvenient to effectively train and recover the lower limb joints of the patient.

[0046] The whole working principle is that in the medical rehabilitation training process, for the patients receiving lower limb surgery, such as knee replacement, hip replacement or fracture repair, the training device helps to recover the joint range of motion and muscle strength, and promotes postoperative rehabilitation. At this time, the training can be carried out with the aid of lower limb joint muscle training equipment. At this time, the lifting control training is carried out by means of the adjusting device 2 arranged on the upper surface of the base 1. First, pull the support rod 203 rotating with the rotary frame 202 on one side of the top plate 201, so that the connecting column 204 fixed at the bottom end of the support rod 203 is clamped and limited in the limiting groove 206 opened in the limiting frame 205 on the surface of the base 1. At the same time, the lifting position of the top plate 201 is adjusted and selected according to the recovery of the patient, so that the connecting column 204 is clamped and protected with the limiting groove 206 at different positions. Then the patient puts one of his legs on the surface of the top plate 201, and then the patient's foot joint contacts the pedal 207 on the bottom surface of the top plate 201.
