The sub light source 36 employs a strip light source, and the end of the sub light source 36 is connected to the second fixing plate 361 in a length direction perpendicular to the thickness direction of the mounting plate 14, so that light emitted from the sub light source 36 is irradiated to the side surface region of the workpiece 70 to be measured.

The second fixing plate 361 is further provided with a hinge hole 3612 and an arc hole 3614 surrounding the hinge hole 3612, the secondary light source 36 is hinged to the hinge hole 3612, the secondary light source 36 is fixed relative to the second fixing plate 361 by penetrating the arc hole 3614 through a second fastening member, and meanwhile, the secondary light source 36 can rotate by unscrewing the second fastening member, and therefore adjustment of a light emitting angle of the secondary light source 36 is achieved, and the secondary fastening member can be screwed again after adjustment is completed.
