An anti-deformation structure of a workpiece with a transverse round hole structure is characterized in that a round supporting plate is arranged at one end and/or two ends of a transverse round hole of the workpiece, the outer diameter of the supporting plate is 0.3-1mm larger than the inner diameter of the round hole, the supporting plate is a round plate or a double-arch-shaped plate, a sector plate and an arc-shaped plate which are provided with notches, and when the supporting plate is provided with the notches, the supporting plate is provided with the notches. The length of the edge, making contact with the inner wall of the round hole, in the supporting plate is larger than or equal to 3/4 of the total length of the edge of the supporting plate. And a plurality of semicircular holes are uniformly distributed at the contact part of the edge of the supporting plate and the inner wall of the circular hole. Under the combined action of a supporting structure in the prior art, deformation of a round hole o
