Small-caliber metal elastic supporting reflector frame

The utility model discloses a small-caliber metal elastic supporting reflector frame, belongs to the technical field of reflector supporting, and aims to solve the problems that in the prior art, thesurface shape precision of a reflector is reduced, the detection error is large, and the reflector structure is easily damaged. The outer contour of the frame body is square, a through hole is formedin the middle of the frame body in the axis direction, and the through hole and a reflector to be supported are supported in a matched mode. Any two opposite edges of the frame body are of an elasticsupporting structure. According to the small-caliber metal elastic supporting reflector frame, the whole reflector frame is made of expansion alloy materials, integrated design is adopted, and the upper end face and the lower end face of the reflector frame are slotted in a long-strip-hole shape, a rectangular shape and a round-hole shape in a machining mode; the elastic coefficient of the scanning reflector frame is change
