Within a certain rotating speed range, the pushing and pulling amplitude is fixed, and the faster the pushing and pulling frequency is, the faster the blade rotates; the push-pull frequency is fixed, and the larger the push-pull amplitude 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 experience person's strength is enough, the blade can high-speed rotation. If the frequency or amplitude of the push-pull decreases, the rotational speed of the blades slows down. Therefore, the user can have pleasurable experience feeling and achievement feeling, the feeling is comfortable and interesting, the effects of entertainment and exercise can be played simultaneously, the user can be exercised in pleasure, and the physical and mental health of the user is benefited. The force changes in the whole push-pull process, and is not rigid like the traditional sports apparatus. 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: one reason for the pleasure that the rapid push and pull of the handle causes the blade to rotate rapidly in the direction of the leading edge is that the sensation of rapid rotation of the blade is transmitted to the body of the user.

The invention has the beneficial effects that: novel structure, the function is various. One or more experience person in coordination pushes away the back and draws handle messenger blade up-and-down motion before, make the blade rotate under the effect of relative air current, be one kind and convert reciprocating motion into circumference pivoted apparatus, when the blade rotational speed is fast, the strength that the preceding pushing back draws both-way motion all needs to use the arm, can play both-way motion's exercise effect, and the strength size can be adjusted dynamically, can give sports and entertainment, body-building, the electricity generation etc. also have the function of physical stamina test comparison, it is recreational strong, experience sense and interest are strong, compare with traditional sports apparatus, more can attract masses to participate in the exercise, will produce far-reaching influence to improving the physical and mental health of the whole people. The multifunctional household lamp is particularly suitable for parent-child experience, is relatively suitable for household use, and can also generate electricity for household illumination. The rotary vane moving machine with super-large size can accommodate more than tens of people, can be installed on the top of urban high-rise buildings, and can be designed into a landmark building. A plurality of leaf-turning sports machines are arranged in a matrix in places such as parks, campuses and the like to form a beautiful landscape.
