The specific embodiment

Fig. 1 illustrates a kind of embodiment of the present utility model.Be made up of first rotary body 1, second rotary body 2, connecting axle 3, bearing 4 and rope 5, first rotary body 1 is connected by connecting axle 3 with second rotary body 2, and bearing 4 is enclosed within on the connecting axle 3, and rope 5 is connected the groove on the bearing 4.One end of bearing 4 extends in first rotary body 1, and a rubber ring 6 is arranged.Second rotary body 2 should with the first rotary body counterweight, make the Climbing top Yo-Yo center of gravity be positioned at groove position on the bearing 4, rope 5 serious friction occurs with arbitrary rotary body in preventing to play.

As shown in Figure 2, in first rotary body 1 energy storage equipment is arranged, this energy storage equipment comprises four swing components, 7,8,9,10, the first swing components 7 and the 3rd swing component 9 symmetries, second swing component 8 and the 4th swing component 10 symmetries.An end of each swing component respectively is hinged on the

projection

12,11,14,13 on the inwall of first rotary body.The end of each swing component has the bearing contact-

making surface

15,16,17,18 that can contact with the rubber ring 6 of bearing 4, and each bearing contact-making surface all is a toothed surfaces, with the possibility of guaranteeing after the contacting of each bearing contact-making surface and rubber ring 6 bigger frictional force to be arranged and reducing slip.Each swing component end respectively has the bigger object of proportion, and for example steel ball is as energy storage block, and this energy storage block is embedded in the

slotted eye

19,20,21,22 of swing component end, and the weight of each energy storage block is preferably identical, and the energy storage block of symmetric position should be identical respectively at least.There is projection 23 at first swing component, 7 middle parts, there is chute 24 at second swing component, 8 middle parts, first swing component 7 and second swing component 8 intersect at the middle part, projection 23 is linked in the chute 24 and can slides in chute 24, makes first swing component 7 and second swing component 8 process of outwards opening keep identical opening angle.There is projection 25 at the 3rd swing component 9 middle parts, there is chute 26 at the 4th swing component 10 middle parts, the 3rd swing component 9 and the 4th swing component 10 intersect at the middle part, projection 25 is linked in the chute 26 and can slides in chute 26, makes the 3rd swing component 9 and the 4th swing component 10 process of outwards opening keep identical opening angle.

As shown in Figure 3, first extension spring 27 connects first swing component 7 and second swing components 8, makes the Climbing top Yo-Yo rotating speed hour, and swing component contacts with the rubber ring 6 of bearing because of spring tension makes bearing contact-making surface 15,16.Second extension spring 28 connects the 3rd swing component 9 and the 4th swing components 10, makes the Climbing top Yo-Yo rotating speed hour, and swing component contacts with the rubber ring 6 of bearing because of spring tension makes bearing contact-making surface 17,18.Under Climbing top Yo-Yo rotated at a high speed, because the centrifugal force of energy storage block and swing component itself, spring was stretched, and the bearing contact-making surface of swing component and the rubber ring of bearing 6 break away from, Climbing top Yo-Yo idle running.First extension spring 27 and second extension spring 28 preferably are connected the medium position of swing component, because centrifugal force is mainly from energy storage block, the arm of force of energy storage block is greater than the arm of force of spring, elastic force difference between two springs is reduced to the influence of swing component, therefore guarantee easily that Climbing top Yo-Yo rotates following four energy storage blocks at a high speed and throws identical distance away, make the Climbing top Yo-Yo balance and stable rotation.

The end of first swing component 7 has extension board 29, and projection 30, the four swing components 10 terminal extension boards 31 are arranged on this extension board 29, on this extension board 31 arc chute 32 is arranged, and projection 30 is enclosed within the arc chute 32.Second swing component, 8 terminal extension boards 33 have the end of arc chute 34, the three swing components 9 that extension board 35 is arranged on this extension board 33, on this extension board 35 projection 36 is arranged, and projection 36 is enclosed within the arc chute 34.Thus, the outside swing of first swing component 7 will drive the 4th swing component 10 by the force transmission of projection 30 and arc chute 32 and outwards swing, otherwise the outside swing of the 4th swing component 10 also force transmission by arc chute 32 and projection 30 drives first swing component 7 and outwards swings.In like manner, the outside swing of second swing component 8 will drive the 3rd swing component 9 by the force transmission of arc chute 34 and projection 36 and outwards swing, otherwise the outside swing of the 3rd swing component 9 also force transmission by projection 36 and arc chute 34 drives second swing component 8 and outwards swings.Therefore, when Climbing top Yo-Yo rotates at a high speed, can remain synchronously outwards swing between four swing components, and keep identical opening angle, the distance that energy storage block equates with the axis of rotation maintenance, under lower-speed state, four swing components keep inwardly shrinking synchronously, make the Climbing top Yo-Yo rotation process can remain balance and stable state.

As shown in Figure 4, on the top of four swing components one annular clutch controller 37 is arranged, this clutch controller 37 has chute 38 on projection 30 positions, on projection 36 positions chute 39 is arranged.The upper end of projection 30 and projection 36 is placed in respectively in chute 38 and the chute 39.Chute 38 and chute 39 respectively have a high-order step 40,41.Driving lever 42,43 is arranged on the clutch controller 37, and this driving lever 42,43 extends in the arcuate socket 44,45 corresponding on the panel of first rotary body 1 (Fig. 5 illustrates).When the driving lever 42 of stirring clutch controller 37 clockwise and/or driving lever 43 make projection 30,36 be in the high-order step 40,41 of chute, four swing components are strutted, bearing contact-making

surface

15,16,17,18 breaks away from the rubber ring 6 of bearing, Climbing top Yo-Yo is in idling conditions completely, help the player particularly the beginner finish exercises under the idling conditions.When stirring clutch controller 37 counterclockwise and making projection 30,36 be in the low level of chute, Climbing top Yo-Yo is in and breaks away from bearing under the common high speed and the state of connection bearing under the low speed.
