Tool for edging plane target material

The utility model discloses a tool for edging a planar target material, and aims to ensure that the length directions of the side edges of the planar target material are consistent when the planar target material is clamped every time, so that the planar target material can be conveniently processed by a grinding machine, and the edging efficiency is improved, and the technical scheme is as follows: the tool for edging the planar target material comprises an electromagnetic chuck, two clamps and two stop blocks, the clamp and the stop block can be magnetically adsorbed on the electromagnetic chuck, the electromagnetic chuck is provided with a concave part for placing a planar target material and two guide grooves communicated with the concave part, and the two guide grooves are symmetrically formed in the two sides of the concave part in the length direction and extend in the direction perpendicular to the length direction of the concave part; the clamp comprises a bottom plate and vertical plates, the bottom
