Abstract

The utility model relates to a separating clamp for a thin-walled part and belongs to the field of aerial precision machinery assembling. The separating clamp for the thin-walled part comprises a tightening assembly and an ejecting assembly, wherein the tightening assembly is formed by a tightening elastic clamping head, tightening sleeves, a pressing nut, handles and a screw; the ejecting assembly consists of an ejecting screw and a pressing block. The separating clamp for the thin-walled part is advantageous in that the handles of the clamp enables the pressing nut to downwardly rotate, so the tightening sleeve is pressed and driven to downwardly move; three paws on the lower end of the tightening elastic clamp head are inwardly retracted; a tip edge can be easily embedded into a seam between two pieces of a product part; and the two pieces of the product are separated via the pressing block when the ejecting screw downwardly moves.
