Slide glass ring

The invention provides a slide glass ring. A slide glass hole for fixedly loading a chip is formed in the slide glass ring, and the inner wall of the slide glass hole is a concave arc face. The circle center of the concave arc face is located at the half thickness part of the slide glass ring. The slide glass hole in the slide glass ring is provided with the concave arc face matched with a chamfered smooth convex arc face of the edge of the chip, the chip is placed in the slide glass hole, and the phenomenon that the chip is slidden out from the slide glass ring during the processing process is avoided, so that the chip is prevented from being crushed, and the yield of chip processing is improved. The slide glass ring provided by the invention is simple in structure, is easy in taking and putting the chip and is stable in processing, and the processing efficiency is improved.
