guide base 100;

The limit cover 200 is embedded in the guide base 100, and the cover body of the limit cover 200 is provided with at least one strip-shaped sliding hole 210;

The light control unit has the same number as the strip-shaped sliding hole 210 , and the light control unit includes a guide groove 310 , which is arranged at the guide base 100 ,

The light-cutting sheet 320 is arranged in the guide groove 310, and the upper surface of the light-cutting sheet 320 is provided with a column 330, the column 330 is arranged through the strip-shaped sliding hole 210, and is in the limit When the cover 200 rotates horizontally, it slides obliquely along the strip-shaped sliding hole 210 .

In this embodiment, according to the above-mentioned assembly, for the assembled linked rotary light control module, when the limiting cover 200 is rotated, the strip-shaped sliding hole 210 will be driven to rotate, so that the column 330 is in the strip-shaped The sliding holes 210 slide obliquely, and then drive the light-cutting sheet 320 to unscrew or close to perform light-cutting. In addition, in this solution, a light-passing hole is arranged in the center of the limit cover, and a light-passing hole is arranged in the center of the guide base 100, and the light-shielding sheet moves to block the light-passing hole to adjust the projection pattern. Light is convenient, and it is convenient for mass production and promotion.

As an optimization, the vertical height of the guide groove 310 is not lower than the thickness of the light-cutting sheet 320 .

In this optimized solution, in order to prevent the limiting cover 200 from extruding the light-cutting sheet 320 excessively, the height of the guide groove 310 is limited. Specifically, in this solution, the vertical height of the guide groove 310 is set to just It is equal to the thickness of the light-cutting sheet 320 , which can ensure that the light-cutting sheet 320 and the limiting cover 200 have a certain frictional force, and can prevent the limiting cover 200 from pressing the light-cutting sheet 320 excessively.

As an optimization, the setting of the bar-shaped sliding hole 210 satisfies that when the upright column 330 slides along one end of the bar-shaped sliding hole 210 to the other end, the light-cutting piece 320 is moved from the slit located in the guide groove 310 to the other end. The innermost position is moved to the outermost.

In this optimized solution, when the uprights 330 are located at both ends of the bar-shaped sliding hole 210, the light-cutting piece 320 is just completely unscrewed or completely closed, so that the space of the entire bar-shaped sliding groove can be used to , there will not be a state where the light-cutting piece 320 cannot be completely unscrewed or completely closed when the column 330 completely passes through the bar-shaped chute, or the light-cutting piece 320 cannot be completely unscrewed or completely closed when the column 330 has not completely passed the bar-shaped chute. It has reached the fully unscrewed or fully closed state.
