Claims

[Scope of Claim for Utility Model Registration] A collimator lens barrel with a built-in collimator lens, a lens barrel fitting hole into which the collimator lens barrel is slidably fitted in the thrust direction, and a plurality of female screw holes. A screwed collimator lens fixing frame and a light source are fixed, and the collimator lens fixing frame is slidably opposed to each other in the radial direction and corresponds to a loose fitting hole that is larger than the female screw hole of the collimator lens fixing frame. The light source fixing frame has a plurality of holes, and a plurality of collimator lens fixing frame elongated screws are screwed into the female screw holes of the collimator lens fixing frame through the loose fitting holes of the light source fixing frame. Features a collimator lens attachment mechanism for laser pointer devices.
