The utility model discloses a theory of operation is: a user sits on the front side of an office table, holds a handle to lift and pull the Y-shaped frame up and down quickly, under the traction of a left connecting rod and a right connecting rod, the dancing vane rotating device moves up and down, the upper surface of the vane and the lower surface of the vane are in alternate windward, at least one of the upper surface of the vane and the lower surface of the vane is convex, the maximum thickness position of the wing section of the vane is close to the front edge of the vane and far away from the rear edge of the vane, the upstream current acts on the convex side of the wing section and is divided into two airflows with different sizes, the small airflow moves towards the front edge direction of the vane, and the large airflow moves towards the rear edge direction of the vane. Due to inertia, the blades will rotate faster and faster during the start-up phase, even if the frequency and amplitude of the lifting and lowering of the Y-frame is constant, as long as a certain frequency and amplitude is maintained. After starting, within a certain rotating speed range, the amplitude of the lifting and pulling up and down is fixed, and the higher the frequency of the lifting and pulling up and down is, the faster the blade rotates; the frequency of the lifting and pulling is fixed, and the larger the amplitude of the lifting and pulling is, the faster the blade rotates. The resistance that the blade moved ahead can increase along with the increase of rotational speed, but when the blade rotated the back, along with the quick increase of the rotatory speed of blade, the reynolds number of blade can increase, and then the acceleration rate of the resistance that the blade moved ahead can slow down, if the user held up with strength and draws Y shape frame, the blade can high-speed rotation. If the frequency or amplitude of the lift is reduced, the speed of rotation of the blades will slow down. The force is changed in the whole lifting and pulling process, and is not rigid like the traditional sports equipment. The up-and-down movement not only overcomes the gravity of the lifting mechanism and the flying blade rotating device to do work, but also overcomes the resistance of the rotating surface of the blade to the air movement to do work. Therefore, when the flying blade device moves downwards, if the resistance of the rotating surface of the blade to the air movement is larger than the sum of the weights of the lifting mechanism and the flying blade device, the flying blade device can rapidly move downwards only by forcibly pulling the Y-shaped frame downwards. Therefore, the user can have pleasurable experience and achievement feeling, the feeling is comfortable and interesting, the functions of entertainment and exercise can be simultaneously played, the user can be exercised in pleasure, and the physical and mental health of the user is benefited. Of course, the movement process of the blades is a very complicated process, and the multiple movements of forward movement, upward movement and downward movement are combined together and are influenced by the local environment such as wind speed and wind direction. Here a simple analysis is made using classical fluid mechanics. The inventor of the scheme proves the motion process through a plurality of physical prototypes: the handle is lifted and pulled up and down quickly in a reciprocating mode, so that the blades can rotate quickly towards the front edge direction, the gyro effect of the rotation of the blades can be transmitted to a user body, the user can feel pleasurable, and the user is relaxed and happy. The user overcomes the gravity of the lifting mechanism and the dancing and rotating device and the air resistance of the blades to do work through the lifting and pulling down handles, thereby achieving the purpose of happy sports and the effect of exercise.

The utility model has the advantages that: the user, namely a person who sits on the seat to work, study or play, can conveniently and fully utilize the fragment time or the time period specified by the organization where the user is located to exercise without leaving the seat, so that the time, the field resource and the money can be saved, and the exercise and exercise cost is particularly low; the handle is held by hand to lift and pull up and down, so that the strength of the arm and the strength of the waist can be exercised, the cervical spondylosis and the scapulohumeral periarthritis can be treated by proper exercise, the body shape of a user can be shaped, and a humpback person becomes straight. Can prevent or reduce cervical spondylosis, scapulohumeral periarthritis, humpback, obesity and even diabetes, and has some curative effect or rehabilitation effect on people suffering from the diseases or symptoms. The utility model discloses multi-functional dancing commentaries on classics leaf desk novel structure, it is wide to use the scene, experiences and feels strong, and recreational strong, is rich in the interest, especially is fit for the office space and uses. The multifunctional table is helpful for people who often work for a long time in front of the table, and the body can be well exercised without leaving the position. The health quality of the whole population (especially white-collar class) is greatly improved.
