Specifically, as shown in fig. 2 and 5, in this embodiment, a limiting baffle 15 is disposed on a side of the bracket away from the fixed end, and a limiting boss (not shown) is disposed on the atomizing assembly or the prism assembly and is matched with the limiting baffle 15, so as to help further maintain the assembly position after the atomizing assembly 2 or the prism assembly 3 is mounted on the boss. The prism assembly 3 or the atomizing assembly 2 extends outward along a side away from the fixed end 121 to form a secondary limiting plate 16, so that the bracket 1 can receive the prism assembly 3 or the atomizing assembly 2 conveniently, the length of the secondary limiting plate 16 of the prism assembly 3 is 1/2 of the length of the outer ring of the second frame 32, the length of the secondary limiting plate 16 of the atomizing assembly 2 is less than 1/2 of the length of the outer ring of the first frame 22, and the secondary limiting plate 16 of the atomizing assembly 2 is disposed on a side close to the wide side 142.
The implementation principle is as follows: an optical component, such as the atomizing component 2 or the prism component 3, is installed from the bottom plate installation end 122 to the fixed end 121, the plug-in unit 41 is inserted into the accommodating space between the bottom plate 12 and the limiting plate 13, the bending part 411 of the plug-in unit 41 is matched with the plugging groove 42, the optical component 2 and the optical component 3 are pressed towards the light through hole 11, the boss of the optical component is matched with the limiting baffle 15 on the bracket for limiting, and the atomizing component 2 or the prism component 3 is assembled with the bracket 1; at this time, the atomizing sheet 21 or the prism sheet 31 completely covers the light passing hole 11. When the optical device is assembled with the atomizing component 2 and needs to swing, the optical device swings to the narrow side 141, the narrow side 141 cuts into the light path until the light path completely corresponds to the atomizing sheet 21, and the wide side 142 performs a reinforcing function and a limiting function on the position of the atomizing component 2. And in the swinging process, the optical device enables the light path not to be interfered except the part of the light through hole frame 14 through the depression 123 of the upper bottom plate 12 of the bracket 1, so that the atomization effect in the cutting process is improved. When the optical device is assembled with the prism assembly 3, the position of the support 1 is limited by the limiting plate 13, the wide side 142 and the like, the driving device 5 is driven by the motor to operate, and drives the third frame 33 of the prism assembly to spin, so that the prism sheet 31 spins, and various prism effects are brought. In addition to the optical unit, a pattern unit 10 (not shown) can be mounted, and the pattern unit 10 includes at least a connector 41 detachably connected to the holder 1.

When the optical device 8 is assembled with the atomizing assembly 2 and swings to the light hole 11 corresponding to the light hole 611, the optical device 8 and the atomizing device 9 realize double atomization effects, as shown in fig. 7. When the optical device 8 is assembled with the prism assembly 3 and swung to the light hole 11 corresponding to the light hole 611, the optical device 8 and the atomizing device 9 achieve the matching effect of prism and atomization, and at this time, the motor 7 can drive the driving device 5 on the optical device 8 to operate and drive the prism sheet 31 to spin, as shown in fig. 6. In this embodiment, the driving gear 51 of the driving device is provided with a magnet, the mounting plate is provided with a magnetic-sensitive positioning plate 612, and the driving device 5 can be temporarily braked by the magnetic-sensitive positioning plate 612 to enable the optical device 8 to be in a specific position or/and enable the prism sheet 31 to be in a static state.
In addition, the atomizing device 9 in this embodiment can be replaced by the optical device described in embodiment 1, so that the optical devices can realize a double atomizing effect, a double prism effect, an atomizing and prism matching effect, and the like through matching of optical components.
