An adjustable laser module mounting device which includes an inner socket fastened to a lens holder through a screw joint to hold a condensing lens by a rubber ring, a laser diode fastened to the inner socket at the back, an adjusting end block, and a printed circuit board connected between the laser diode and the adjusting end block. The focal distance of the condensing lens is adjusted by rotating the lens holder on the inner socket in either direction. The alignment of the laser diode with the condensing lens is adjusted by turning the adjusting end block in either direction.
