The striking hammer 55 and the struck portion 6 have a certain gap therebetween, and are not in contact with each other, and when the intermediate rotation body 5 is struck by an external force, the striking hammer 55 is elastically deformed, and at this time, the striking hammer 55 is in contact with the struck portion 6 to strike the struck portion 6, and after the external force is removed, the outer ring 51 returns to its original shape, and at this time, the striking hammer 55 is separated from the struck portion 6 by a certain gap.

When the middle revolving body 5 is hit by the hitting tool, the middle revolving body 5 is elastically deformed to generate a large advancing power for the disc ball, and at the same time, the middle revolving body 5 is caused by an external force to rotate and hit the hit part 6, so that the first revolving body 2 and the second revolving body 3 rotate to realize the advancing and rotating of the disc ball.

Intermediate rotor 5 rotates or is fixed relative to one or both of first rotor 2 and second rotor 3, and in the present embodiment, intermediate rotor 5 is independently rotatable relative to both of first rotor 2 and second rotor 3.

Of course, in other embodiments of the present invention, the included angle between each two adjacent elastic supporting members 52 may be different, that is, the elastic supporting members 52 for supporting the outer ring 51 are not necessarily uniformly distributed around the inner ring 53.

The number of the striking hammers 55 for striking the struck portion 6 is at least two, the striking hammers are evenly distributed around the outer ring 51, and the central angles corresponding to every two adjacent striking hammers 55 are equal, and in the embodiment of the present invention, it is preferable to provide 4 striking hammers 55, and the central angle corresponding to every two adjacent striking hammers 55 is 90 degrees. Of course, in other embodiments of the present invention, the central angles of two adjacent striking hammers 55 may not be equal, i.e. the striking hammers do not have to be evenly distributed around the outer ring 51.

In the embodiment of the present invention, the number of the struck portions 6 uniformly distributed in the first rotating body 2 and the second rotating body 3 is at least two, and the central angles corresponding to every two adjacent struck portions 6 are equal, and in the embodiment, it is preferable to provide 4 struck portions 6, and the central angle corresponding to every two adjacent struck portions 6 is 90 degrees.

The specific operation process of the embodiment of the invention is as follows:

first, the intermediate rotation body 5 is rotated by the starter, and the entire disc is kept standing by the universal ball 4 at the lower end of the second rotation body 3 as a support point due to the gyro effect of the rotation, and at this time, the first rotation body 2 and the second rotation body 3 are not rotated. The outer ring 51 of the middle rotator 5 is hit by applying external force, so that the outer ring 51 is elastically deformed, at this time, the hitting hammer 55 and the hit part 6 are contacted and hit the hit part 6, so that the first rotator 2 and the second rotator 3 start to rotate, after the external force is removed, the outer ring 51 recovers the shape, the hitting hammer 55 and the hit part 6 are separated, the outer ring 51 is continuously applied with external force to cause the outer ring to elastically deform, and the hitting hammer 55 is continuously hit the hit part 6, so that the first rotator 2 and the second rotator 3 are caused to rotate.

In addition, the outer ring 51 is made of an elastic material, the elastic material can effectively avoid energy loss caused by collision between a force application object and the disc ball, the collision energy is converted into elastic potential energy, when an external force is applied, the outer ring 51 can generate a reaction force, and the elastic potential energy enables the whole disc ball to travel a longer distance in the force application direction, so that the aim of improving the movement distance of the disc ball, which is realized in the invention, is fulfilled.

In the embodiment of the present invention, the moving time of the disc ball is increased by providing the motor 9, the control part 10, and the power source 11 inside the first rotating body 2 and the second rotating body 3, and the power source 11 supplies power to the motor 9 and the control part 10. The output shaft of the motor 9 is connected with the rotating shaft 1, a rotation speed detecting element is arranged in the control part 10, after the starting device is used for starting the rotation of the disc, the control part 10 starts to work, because the friction exists between the first bearing 7 or the second bearing 8 and the rotating shaft 1 and between the first rotating body 2 or the second rotating body 3 and the air, after energy consumption, the rotation speed of the first rotating body 2 or the second rotating body 3 can be reduced, when the detecting element detects that the rotation speed of the first rotating body 2 or the second rotating body 3 is lower than a certain specific value, the motor 9 is started, the rotating shaft 1 rotates reversely relative to the first rotating body 2 or the second rotating body 3, and therefore a reaction force is generated to promote the second rotating body 2 and the second rotating body 3 to accelerate the rotation speed, and the long-time rotation of the disc can be maintained after. The driving is stopped when the rotation speed exceeds a certain set value, or the motor 9 may be started for a certain time and stopped, in the embodiment of the present invention, the rotation speed of the first rotating body 2 or the second rotating body 3 is detected to exceed a certain set value and stopped.

The foregoing detailed description of the embodiments of the present invention is intended to be illustrative, but not limiting, of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, and these variations and modifications are within the protective scope of the present invention. Therefore, the protection scope of the present invention should be subject to the claims.
