The base 1 is also provided with a turbine gear motor assembly 11 with a driving pulley, and the driven pulleys 2-2-3 are driven to rotate through a transmission belt 12.

The action principle of the invention is as follows: the degree of expansion of the electric push-pull rod 2-9 controls the included angle between the upper rotary support arm body and the lower rotary support arm body around the horizontal pin shaft 2-11. Because the horizontal pin shaft 2-11 is coincident with the center of the cross shaft of the cross universal joint 2-4, the joint formed by the upper rotary support arm body 2-5-1 and the lower rotary support arm body 2-2-1 can flexibly rotate around the lower support shaft 2-1 within a certain angle range.

When the electric push-pull rod 2-9 is contracted to the bottommost position, namely, the upper support shaft 2-6 and the lower support shaft 2-1 at the two ends of the cross universal joint 2-4 are in coaxial positions, and the foot pedal 3 is in a horizontal state;

when the electric push-pull rod 2-9 is in the highest position, namely the upper support shaft 2-6 and the lower support shaft 2-1 at the two ends of the cross universal joint 2-4 are in the maximum stretching angle position, and the pedal plate 3 is in the maximum inclination state.

When the turbine speed reducing motor assembly 11 is started to drive the rotary control arm assembly 2 to rotate, the pedal 3 fixed on the support shaft 2-6 on the rotary control arm assembly 2 swings along with the rotary control arm assembly 2. The swing amplitude of the pedal plate 3 is controlled by the telescopic length of the electric push-pull rods 2-9, and the swing direction of the pedal plate 3 is changed by rotating the control arm assembly 2.

As shown in fig. 15 to 20, the specific exercise method is as follows:

initial state: the device is in a reset state, namely the pedal 3 is in a horizontal position, and the rotary control arm assembly 2 faces to the right front. The person stands on the foot rest 3, and the feet are horizontally placed at the corresponding positions of the foot rest;

preparation: setting the rotating speed, the cycle number and the running track of the rotating control arm assembly 2 through the controller 10; the safety belt 7 is buckled, the lifting support 8 is adjusted to enable the head fixing device 9 to be sleeved on the head of a human body, and the lifting support 8 is locked through the locking wrench 16.

Starting the instrument: pressing the inflation key on the controller 10 to a given pressure will automatically stop and give a prompt tone; pushing the control key of the hand-held controller 15 back and forth, controlling the electric push-pull rod 2-9 to adjust to a proper inclined position, at this time, the human body will lean back slowly because the direction of the rotary control arm assembly 2 is in front, and keeping the whole body and neck to be tensioned, so that the body is close to the feet and the head support to keep the gravity center stable.

Exercise process: pressing the control key of the hand-held controller 15, the lower rotary support arm assembly 2-2 of the rotary control arm assembly 2 drives the inclined upper rotary support arm assembly 2-5 to start rotating. As the rotation angle changes, the inclination direction of the human body changes, and the tension and the relaxation of muscles at corresponding positions are caused; until the setting cycle is completed, the instrument is reset.

Resetting: the direction of the rotary control arm assembly 2 is right in front, the pedal plate 3 returns to a horizontal state, and one exercise is finished. When the control key of the hand-held controller 15 is pressed again in case of emergency, the instrument will be reset directly.

In addition to the embodiments described above, other embodiments of the invention are possible. All technical schemes formed by equivalent substitution or equivalent transformation fall within the protection scope of the invention.
