The hemming mechanism in the prior art first composites the skeleton and the skin, and then hems some relatively large and relatively flat areas. However, for some corners and relatively complex surfaces, the hemming effect is unstable and extremely difficult to control because the machine hemming only produces local deformation, which will damage the corner edges and produce defects such as sharp points, waves, and warping deformation. Therefore, manual hemming is usually required, which leads to low production efficiency and low product qualification rate. Utility Model Content
