A limiting plate 20 is arranged in the middle of the upright rod 1, a third spring 19 is arranged between the limiting plate 20 and the cross rod 2, the third spring 19 is sleeved on the upright rod 1, and when the handle is not used, the third spring 19 has a supporting effect on the cross rod 2 and the blades 4 connected to the cross rod 2, so that the handle is suspended at a certain height, and the use of an operator is facilitated; in the use process, after the cross rod 2 is pulled down, the third spring 19 is compressed to have elastic potential energy, and the cross rod 2 and the blades 4 can be assisted to bounce, so that the lifting is comfortable. In addition, in the process of reciprocating pressing of the third spring 19, the third spring 19 itself or the third spring 19 and the upright rod 1 rub against each other to generate rhythmic sound, which can enable an operator to generate certain sound therapy effect, so that the brain can be excited, and brain coating cells can be activated over time, and the attention, memory, imagination and creativity are improved, so that people are more healthy.

The lower extreme of pole setting 1 is connected with support frame 16, and support frame 16 reaches the effect that has the support to the whole, is provided with second spring 17 between sleeve 6 and the support frame 16, and second spring 17 cup joints on pole setting 1, and second spring 17 has the supporting role to sleeve 6 and seat 7.

The basic working principle of the pile-fixing vertical-lift flying dancing device is as follows: the handle is held by hand to push and pull the cross rod 2 up and down quickly, so that the cross rod 2 makes reciprocating linear motion, under the traction of the cross rod 2, the blade 4 moves up and down, the upper surface 43 of the blade and the lower surface 44 of the blade face the wind alternately, at least one of the upper surface 43 of the blade and the lower surface 44 of the blade is convex, the maximum thickness position of the wing section of the blade 4 is close to the front edge 41 of the blade and far away from the rear edge 42 of the blade, the head-on incoming flow is divided into two air flows with different sizes when acting on the convex surface of the wing section, the small air flow moves towards the front edge 41 of the blade, and the large air flow moves towards the rear edge 42 of the blade, so that a momentum difference is formed between the front edge 41 of the blade and the rear edge 42 of the blade, the air flow pushes the blade 4 to move towards the front edge 41 of the blade, and then the blades 4 rotate around the inner ring of the bearing 3 together. Within a certain rotating speed range, the upper and lower push-pull amplitude is fixed, and the faster the upper and lower push-pull frequency is, the faster the blade 4 rotates; when the frequency of the up-and-down push-and-pull is fixed, the larger the amplitude of the up-and-down push-and-pull is, the faster the blade 4 rotates. The resistance of the blade 4 to move forward increases with the increase of the rotating speed, but after the blade 4 rotates, the reynolds number of the blade 4 increases with the rapid increase of the rotating speed of the blade 4, the increase of the resistance of the blade 4 to move forward slows down, and if the operator pushes and pulls the cross bar 2 hard, the blade 4 rotates at a high speed. Therefore, the operator has pleasurable experience and achievement feeling, feels comfortable, can play the roles of entertainment and fitness at the same time, enables the operator to exercise in pleasure, and is beneficial to the physical and mental health of people. If the frequency of the push-pull decreases or the amplitude decreases, the rotational speed of the blades 4 will slow down. The force changes in the whole pushing and pulling process, and is not stiff like the traditional fitness equipment. Of course, the movement process of the blades 4 is a 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 rapid up and down reciprocation of the push-pull handle causes the vane 4 to rotate rapidly in the direction of the leading edge and the operator feels pleasure.

In addition, when an operator pulls the handle downwards, the third spring 19 is squeezed to exert an upward acting force on the cross rod 2 and the handle, the handle and the second spring 17 exert an upward pulling and pushing acting force on a human body, so that the sleeve 6 and the seat 7 (communicated with the operator) gradually rise in the vertical rod 1, and when the sleeve 6 rises, the chucks 81 of the rotating plate 8 in the limiting and locking mechanism are embedded into the bayonets 10 one by one from bottom to top, so that the operators on the sleeve 6, the seat 7 and the seat 7 can achieve the purpose of only ascending upwards but not downwards in a single direction, and when the operators fall after rising to a high position, the operators can pull the handle downwards slightly, so that the sleeve 6 can move upwards for a small distance (assuming that the bayonets 10 are arranged above, and the chucks 81 do not enter the last bayonet 10 again), in order to separate the chucks 81 of the rotating plate 8 from the bayonets 10, at this time, the operator pushes down the upper end of the rotating plate 8 to keep the chuck 81 separated from the bayonet 10, and at this time, the sleeve 6, the seat 7 and the operator on the seat 7 (at this time, the operator still holds the handle) fall straight at a high speed, so that the blades are pulled to rotate at a high speed, and the joyful feeling is strong.
