[0040] In this embodiment, both the upper fixing plate 101 and the lower fixing plate 102 are annular structures. Specifically, the upper fixing plate 101 is provided with a detection hole 1011 for acquiring image information of the workpiece to be measured, and the lower fixing plate 102 is provided with a workpiece passing hole 1021 for the workpiece to be measured to enter and exit the light-illuminating space.
