High guiding mechanism of diffuser plate support

The utility model belongs to the three -dimensional measurement field of structured light, concretely relates to high guiding mechanism of diffuser plate support, the on -off device comprises a base, the base top is provided with supports the end, is supporting the inside stiff end that is provided with of end, the stiff end top is connected the outside through the bearing and is provided with capitate gear ring, capitate gear intra -annular portion is provided with the screw thread to through the threaded connection lifter, lifter top linking bridge, inside is provided with non - centrosymmetric hollow structure, the inside rod of inserting that inserts hollow structure that is provided with of stiff end, the lift knob passes through the connecting rod and supports end connection conical tooth wheel, the conical tooth wheel connects with capitate gear linkage, through rotating the lift knob, it is rotatory to utilize the conical tooth wheel to drive capitate gear ring, relies on the lifter unable rotatory along with capitate gear ring, and adjustment about realizing going on lifter top support effectively improves the diffuser plate to the inhibitory effect of highlight, and then improves three -dimensional measuring accuracy.
