When the collimating lens mechanism 20 needs to be adjusted to the second position, the positioning elastic piece 3332 is pulled out, the screw rod 332 can rotate, the screw rod assembly is driven to rotate through external force, and when the positioning elastic piece 3332 is rotated to be clamped with the other positioning groove 3321, the collimating lens mechanism 20 is just positioned at the second position and aligns to the second illuminant to collimate the light beam.
