A demonstration video can be found at https: / / v.qq.com / x / page / l0129bxujlh.html. The rotating device includes:

[0036] The swing arm drive assembly is mounted on the support frame 1 and connected to the swing arm 2, and is suitable for driving the swing arm 2;

[0037] The magic wheel drive assembly, connected to the swing arm 2, includes a first motor 3 fixedly mounted on the swing arm 2, a first drive gear 4 mounted on the first motor 3, a first driven gear 5 located on one side of the swing arm 2, and a transmission assembly connected to the first driven gear 5.

[0038] The swing arm drive assembly may include electrodes mounted on the support frame 1, which directly drive the swing arm 2 via a motor. The magic wheel 6 generally has a groove, and the swing arm drive assembly, the swing arm 2, and the magic wheel drive assembly are located on the side of the magic wheel 6 with the groove. The magic wheel 6 obscures the swing arm drive assembly, the swing arm 2, and the magic wheel drive assembly during the performance of the action demonstration.

[0039] This application replaces the belt drive in the prior art with gear transmission, which reduces the distance between the first motor 3 and the rotating shaft in the transmission assembly, thereby making the size of the magic wheel 6 smaller and saving space.

[0044] The second motor 7 can drive the second driven gear 9 to rotate via the second driving gear 8, thereby causing the swing arm 2 to swing. The central axis of the second driven gear 9 coincides with the central axis of the first driven gear 5, which allows the magic wheel 6 to block the swing arm drive assembly without changing the size of the magic wheel 6.

[0045] In one embodiment, the swing arm drive assembly further includes:

[0046] The first rotating shaft 10 is fixedly connected at one end to the end face of the second driven gear 9 away from the swing arm 2;

[0050] The second motor 7 and the first rotating shaft 10 can be located on the same side of the second driving gear 8 and the second driven gear 9, specifically, on the side away from the magic wheel 6.

[0051] In one embodiment, the swing arm 2 is U-shaped, with one arm connected to the second driven gear 9, and the transmission assembly and the first motor 3 both connected to the other arm of the swing arm 2. This makes it easier for the magic wheel 6 to complete the display action.

[0056] The first motor 3 can drive the second rotating shaft 13 to rotate through the first driving gear 4 and the first driven gear 5, thereby driving the magic wheel 6 to rotate.

[0057] In one embodiment, a second bearing is provided between the support tube 12 and the second rotating shaft 13. This allows relative rotation between the support tube 12 and the second rotating shaft 13. There can be two second bearings, respectively located at both ends of the second rotating shaft 13.

[0058] In one embodiment, the central axis of the second rotating shaft 13 coincides with the central axis of the magic wheel 6. This makes the rotation of the magic wheel 6 more stable.
