Rotary prism device

The utility model relates to the field of prism devices, in particular to a rotating prism device which comprises a base, a rotating mechanism and a locking mechanism, the rotating mechanism used for adjusting the transverse direction of a prism is arranged in the base, the upper end of the rotating mechanism is connected with a connecting disc, and a support is fixedly installed at the upper end of the connecting disc. And a locking mechanism for longitudinally adjusting the direction of the prism and then fixing the prism is arranged on the upper side of the bracket. When the transverse direction of the prismatic lens needs to be adjusted, the motor is controlled to operate to drive the gear to rotate, and the gear block arranged on the outer wall is meshed to drive the fluted disc to rotate, so that the connecting disc is driven to rotate, the support fixedly installed at the upper end is driven to rotate, the transverse direction of the prismatic lens is adjusted, and the insertion block is driven to stab
