Light spot shape conversion structure of laser pointer

摘要

To provide a structure for converting a light spot shape of a laser pointer which is simple in structure, easy to assemble and low cost.SOLUTION: The light spot shape converting structure of a laser pointer comprises a tube 1 and a rotating disc. The tube 1 is provided at one end of the laser pointer 3 and has an end face 12. The end face 12 has a perforation 13 and a pivot hole 14. In the tube 1, a light emitting element 4 which emits a laser beam and emerges from the perforation 13 is accommodated. The turntable is pivotally connected to the pivot hole 14 of the end face 12 via the pivot 21, and extends in the radial direction, and a part of it is exposed from the tube body 1. On the rotating disc, a plurality of deformable lenses corresponding to the perforations 13 are disposed by turning, and when the laser light passes through the deformable lens, the shape of the light spot changes.(FIG.
