The electric control box 22 is internally provided with a battery and a controller. The motor 21, the battery and the controller are electrically connected. The battery is used to supply power to the motor 21, so that the visual mechanism 5 can realize long-time rotating movement and the operation time is improved.

[0040] The inner visual assembly 52 comprises an inner rotating disc 521 and inner rotating strips 522, the inner rotating disc 521 is sleeved on the rotating shaft 51, and the rear side thereof is fixedly connected with the front side of the second belt pulley 431; the inner rotating strips 522 are fixedly arranged on the outer side wall of the inner rotating disc 521, and a plurality of inner rotating strips 522 are arranged on the inner rotating disc 521 in a circumferential direction; the second belt pulley 431 rotates on the rotating shaft 51 in a direction opposite to the rotating direction of the rotating shaft 51, drives the inner rotating disc 521 to rotate on the rotating shaft 51, and drives the outer rotating strips 532 to rotate with the outer rotating disc 531; the rotating directions of the outer rotating strips 532 and the inner rotating strips 522 are opposite, and a 3D dynamic visual effect is formed.

[0041] The working mode of the utility model is as follows:

[0042] The motor 21 is started by using a remote device such as a remote controller, the motor 21 drives the driving gear 31 to rotate, the driving gear 31 drives the driven gear 33 to rotate, the driven gear 33 drives the first transmission shaft 32 to rotate, so that the first transmission gear 34 rotates, the first transmission gear 34 drives the second transmission gear 36 to rotate, and the second transmission shaft 35 rotates. When the second transmission shaft 35 rotates, the main belt pulley 41 rotates, the main belt pulley 41 drives the first belt pulley 421 to rotate in a forward direction through the first belt 422, so that the rotating shaft 51 rotates in a forward direction, and the outer visual assembly 53 rotates in a forward direction, and at the same time, the main belt pulley 41 drives the second belt pulley 431 to rotate in a reverse direction through the second belt 432, the second belt pulley 431 drives the inner visual assembly 52 to rotate in a reverse direction, and finally the inner visual assembly 52 and the outer visual assembly 53 rotate in opposite directions, and a 3D dynamic visual effect is formed.
