The reflecting portion 281 in this embodiment is provided with a reflecting surface, and specifically includes a second reflecting surface 281a and a third reflecting surface 281b, where the second reflecting surface 281a is a horizontal plane located at the top end of the second rotating shaft 28, and has a regular polygon shape, and the third reflecting surface 281b is similar to a fan-shaped ring, but has a linear top end. The third reflective surface 281b is inclined downward and outward from the edge of the second reflective surface 281a, and forms a fourth included angle with the axis of the second rotating shaft 28, where the number of the second reflective surface 281a and the third reflective surface 281b in this embodiment is six, and the fourth included angle is an acute angle. It will be appreciated that in other embodiments of the present invention, the second reflective surface 281a may not be provided such that the tips of the third reflective surfaces 281b intersect at a point, and in such embodiments, the third reflective surface 281b is fan-shaped. The second contact portion 283 is located below the reflective portion 281, and the second contact portion 283 of the present embodiment is similar to a cylinder shape, and has a diameter equal to that of the upper half of the second shaft hole 25, so that the second contact portion 283 can contact and support the inner surface of the second shaft hole 25 when the second shaft 28 is disposed in the second shaft hole 25, thereby preventing the second shaft 28 from shaking in the second shaft hole 25. The second clamping portion 282 is located below the second contact portion 283, and the second clamping portion 282 in this embodiment is a flange protruding out of the second rotating shaft 28 along a radial direction, and the flange and the second rotating shaft portion on the upper portion form a step surface to cooperate with the second shaft hole 25 provided on the rotating wheel 20 to position the second rotating shaft 28 into the second shaft hole 25 of the rotating wheel 20. The supporting portion 284 is located below the second positioning portion 282, the supporting portion 284 of this embodiment is cylindrical, an arc-shaped protrusion 284a is disposed at the bottom center of the supporting portion 284, and a first element of the position sensing assembly is disposed at the edge of the supporting portion 284. The protrusion 284a and the second bushing 14 below the protrusion constitute a spherical friction pair, so that the contact area between the second rotating shaft 28 and the second bushing 14 can be reduced, and the abrasion of the second rotating shaft 28 can be reduced.

Referring to fig. 9 in particular, when the LED lamp works, the light emitted by the LED lamp is condensed by the condensing surface 271a and then transmitted downwards, and the transmitted light path is divided into the following parts: a portion of the light passes through the first transmissive surface 274a and is directed toward the inner cylindrical surface of the wheel 20; a part of the light is irradiated to the first reflecting surface 274d, reflected to the second transmitting surface 274b opposite thereto, and transmitted to the inner cylindrical surface of the wheel 20 through the second transmitting surface 274 b; the other part of the light passes through the third transmission surface 274c directly, irradiates the second reflection surface 281a or the third reflection surface 281b, and is then reflected from the second reflection surface 281a or the third reflection surface 281b to the inner cylindrical surface of the wheel 20. Thus, the light rays transmitted through different paths pass through the rotating wheel 20 and then pass out of the diamond cutting surface on the surface of the rotating wheel 20. Because the included angle is designed between the diamond cutting surfaces, the colorful effect can be achieved by the light rays emitted from the surface of the rotating wheel 20. Since the wheel 20 can rotate, the color effect will change continuously as a ticker, with the color effect also accompanied by a color change effect due to the angle.

It should be noted that, not all types of light emitted by the LED lamp can pass through the first transmission surface 274a and pass through the inner cylindrical surface of the rotating wheel 20, specifically, whether the light can pass through the first transmission surface 274a and pass through the inner cylindrical surface of the rotating wheel 20, depending on the coverage area of the light emitted by the LED lamp and the condensing degree of the condensing surface 271a, if the coverage area of the light emitted by the LED lamp is smaller or the condensing degree of the condensing surface 271a is stronger, no light passes through the first transmission surface 274a and passes through the inner cylindrical surface of the rotating wheel 20. It should be noted that, the angles of the first transmitting surface 274a, the second transmitting surface 274b, the third transmitting surface 274c, the first reflecting surface 274d, the second reflecting surface 281a, and the third reflecting surface 281b are specifically designed according to the reflection and refraction rules, and all the transmitted light rays are perpendicular to the corresponding surfaces when passing out.

Referring to fig. 2 and 14, the second bushing 14 is located below the second rotating shaft 28. The second bushing 14 includes a disk-shaped bushing bottom portion 141 and a receiving portion 142 formed by extending upward from a position near an edge of the bushing bottom portion 141, the receiving portion 142 being hollow and cylindrical, a space for receiving the second rotation shaft 28 being formed therein, and a supporting portion 284 of the second rotation shaft 28 being located in the space and forming a spherical friction pair with the bushing bottom portion 141 of the second bushing 14.

Further, the edge of the bushing bottom 141 is provided with a plurality of spring plates 144 extending obliquely downward, and the spring plates 144 are abutted against the second circuit board support 17 below the second bushing 14, so as to eliminate the gap between the rotating wheel 20 and the first rotating shaft 27 and the second rotating shaft 28 and play a role in buffering. In the present invention, the stiffness of the spring 144 structure takes into account the weight of the wheel 20 and the effects of jounce road acceleration.
