Fidget spinner bearings is a kind of a symmetric structure

Fidget spinner bearings is a kind of a symmetric structure, the bearing can be turned over the finger small toys, it is composed of a two-way or multi-directional symmetry body as the main body, the design of the embedded in the middle of the main body of a bearing, a whole structure of plane rotation of new items, the basic principle of this item is similar to traditional gyroscope, but need to use a few fingers to grasp and to keep its rotation.
Appearance of fidget spinner bearings:

Material for fidget spinner bearings: Zinc alloy, copper, stainless steel, titanium alloy, liquid metal (amorphous alloy)
Bearings: any light bearing is acceptable.
The principle of fidget spinner bearings:
The fidget spinner bearings is composed of a bidirectional or multi-directional symmetric body as the main body, with a bearing embedded in the middle of the main body as the design combination, which forms a new type of item that can be rotated in a plane. The basic principle of this item is similar to that of the traditional gyro, but it needs to be grasped and fingered by several fingers to make it rotate.
The effect for fidget spinner bearings:

The fidget spinner bearings has only one main physical effect, that is, it relies on the bearing rolling principle to achieve the rotation effect. To play the fingertip gyro, only the pinching force of the thumb and another finger is needed to provide the fixed fulcrum, and then the third finger fingertip is used for the fingering to make it rotate.In addition, the appearance design, shape structure, main material and surface treatment of the fingertip gyro are not the same and the appearance of innovation also emerge in endlessly, so the spinning effect of the fingertip gyro is diverse and plastic.
