Anti-deformation tool for heat treatment of metal thin-wall plate

The invention relates to the field of heat treatment, in particular to an anti-deformation tool for heat treatment of a metal thin-wall plate. The anti-deformation tool comprises first positioning parts, second positioning parts and adjusting parts, the two first positioning parts and the two second positioning parts are assembled to form a regular quadrilateral, connecting holes and positioning holes are connected through bolts correspondingly, when the metal thin-wall plate is arranged between the first positioning parts and the second positioning parts, the front face of the metal thin-wallplate abuts against the two second positioning parts, and the back face of the metal thin-wall plate abuts against the adjusting parts. According to the provided anti-deformation tool for the heat treatment of the metal thin-wall plate, the mass of the provided anti-deformation tool is smaller than that of a heat treatment tool in the prior art, meanwhile, the distance between the two second positioning parts can be adju
