Further, as shown in fig. 1, 2, 14 and 15, when the trainee performs the splitting movement, the power supply of the first splitting movement motor 2 is switched on, the program of fig. 14 is operated to automatically perform the splitting movement, when the set splitting opening degree is reached, the pedal 35 is contacted with the limit delay switch 42 to stop the splitting movement, after the delay time is reached, the power supply of the motor is switched on again, the program of fig. 15 is operated to automatically perform the leg retracting movement, after the leg retracting and closing movement reaches a certain degree, the pedal 35 is contacted with the other limit delay switch 42 to stop the leg retracting movement, and the primary splitting movement is completed. After the time delay is reached, the second splitting movement is automatically started, and the process is repeated. When the training is to be stopped or completed, the motor control switch 39 is closed.

The working principle is as follows:

firstly, a control switch 39 is turned on, the trainer stands in front of a camera 38 in a natural state, the camera 38 transmits parameters of the height, the leg length, the posture and the like of the trainer to a controller, a database and an expert system in the controller calculate motion parameters required by the trainer, and the motion parameters are displayed or broadcasted by voice on a display 40. The invention does not limit the sequence of each movement because of the difference of each person's skill level, quality, posture, etc.

When the trainer carries out stretching exercise, the trainer sits on the chair 20, holds the pull ring 17 with one hand to lift the pawl, rotates the handle 5 with the other hand, loosens the hand after adjusting the canvas belt 16 to a proper height, hangs the annular canvas belt 16 at the chin of the human body, hangs the nylon adhesive buckle canvas belt 16 at the back of the brain spoon, and fastens the nylon adhesive buckle canvas belt 16 after adjusting proper tightness. Then the handle 5 is rotated to adjust the tensile strength to the recommended value of the expert system, and the stretching exercise is carried out. When the trainer needs to stop the stretching exercise, the user holds the pull ring 17 with one hand to lift the pawl, rotates the handle 5 with the other hand, loosens the nylon rope 13, and removes the canvas belt 16 from the head of the human body. In the process of stretching movement, in order to ensure the uniformity and the progressiveness of stretching muscles of all parts of cervical vertebra, vertebra and lumbar vertebra, the upper body of a trainer cannot swing back and forth and left and right, the rotating handle 5 needs to be slow, the stretching strength is gradually increased, otherwise, the effect is poor, and sometimes even the injury phenomenon can occur.

Then the trainer leans back on the arch-shaped plate 30 to press the waist close to the arch-shaped plate 30, the head tilts backwards and sinks, the left hand and the right hand grab pull holding rod slowly descend simultaneously to complete one waist-down movement, then the left hand grab push holding rod slowly rises, and the above steps are repeated to perform waist-down training movement. When the trainer performs leg pressing movement, firstly, the height of the leg pressing cross rod 45 is adjusted through a hydraulic system according to the recommended value of an expert system. Then the trainer places one leg on the leg pressing cross rod 45 sleeved with the rubber tube, stands the other leg on the frame 1, rhythmically carries out leg pressing training, and after fine movement for a certain time or reaches a certain leg pressing strength, the two legs are exchanged, and the steps are repeated so as to finish leg pressing training movement. The pressure sensor can monitor the leg pressing strength of the trainer in real time and display or voice broadcast on the display 40. Therefore, the trainer can adjust the leg pressing strength in time, and the injury can be avoided while the training effect is improved.

In order to save electric power during the lower waist exercise or leg pressing exercise, the power supply of the hydraulic motor should be disconnected.

When a trainer performs split movement, the installation positions of the two limit delay switches 42 are determined according to the leg length of the trainer, the natural standing width of two feet and the technical level, and the split speed is adjusted by adjusting the rotating speed of the motor or the transmission. When the side splitting movement is performed, the countersunk head screws 37 are unscrewed, and the pedal 35 is adjusted to be horizontal, i.e., the long side faces the front-back direction, and the short side faces the left-right direction; the grub screw 37 is then tightened again to adjust the pedal 35 laterally as the front split movement is performed. The split motion can be automatically performed by placing the pad 36 into the pedal 35, standing both feet on the pad 36, and then pressing the control switch 39. When the split movement needs to be stopped or ended, the power supply can be cut off by pressing the control switch 39.
