[0028] The working principle of the utility model is as follows: when in use, the medical staff first moves the device to the treatment position of the child suffering from rheumatism and immune disease, and then the medical staff uses the brake pad 4 to lock the universal wheel 3, and then makes the child lie on the bed 1, and then the medical staff pulls the connecting column 9 to the side close to the bed 1 according to the child's own training status, so that the connecting column 9 slides off the turntable 7, and then the medical staff rotates the turntable 7, so that the turntable 7 drives the rotating shaft 210 to rotate, so that the rotating shaft 210 drives the second conical wheel 211 to rotate, and then the second conical wheel 211 drives the first conical wheel 209 to rotate, so that the first conical wheel 209 drives the threaded rod 205 to rotate, and at the same time the threaded rod 205 drives the connecting plate 206 and the pressure sensor 207 to adjust the position, so that the medical staff adjusts the pressure sensor 207 and the movable plate 2 according to the needs. 04. When the adjustment is completed, the medical staff loosens the connecting column 9, so that the connecting column 9 is clamped in the inside of the turntable 7 under the action of the elastic force of the connecting spring 8, thereby locking the rotating shaft 210. Then the child places his feet on the placement frame 203 and turns on the rotating motor 202. The power provided by the rotating motor 202 is used to drive the ball screw 201 to rotate, so that the ball screw 201 drives the placement frame 203 to move to the side close to the pressure sensor 207, and then the placement frame 203 drives the child's legs to bend. When the moving plate 204 contacts the pressure sensor 207, the pressure sensor 207 transmits a signal to the controller 208, so that the controller 208 controls the rotating motor 202 to rotate in the opposite direction, so that the placement frame 203 moves back to its original position, and then repeats the training to help children with rheumatic immune diseases to perform activity training.
