In addition, because the household appliance glass 11 is limited by the upper T-shaped strip 8 and the lower T-shaped strip 8, when the template 15 is contacted with the household appliance glass 11, the T-shaped strip 8 at the upper end is removed, so that the template 15 is completely contacted with the household appliance glass 11; when the household appliance glass 11 needs to be rotated, the two T-shaped strips 8 can limit the household appliance glass 11, meanwhile, in order to prevent the household appliance glass 11 from sliding out of the T-shaped strips 8 in the rotating process, the arc-shaped plate 10 is arranged, so that the barrier strips 8-2 are in contact with the arc-shaped plate 10, the arc-shaped plate 10 can limit the barrier strips 8-2, and meanwhile, as the limit strips 8-4 are arranged at one side close to the barrier strips 8-2, when the T-shaped strip 8 at the upper end is taken out, the T-shaped strip 8 directly slides out of the rotating block 8-1;

because the top surface of arc 10 is highly parallel and level with under the household electrical appliances glass 11 horizontality, consequently when taking out T type strip 8, need set up household electrical appliances glass 11 slope, can be with T type board roll-off.

The product is successfully applied to the panel glass of the refrigerator, the pioneer of the 113D three-dimensional fine texture expression of the household appliance glass is created, the appearance of the household appliance is brought into a new era of 3D three-dimensional effect from now on, the product is a technical revolution, and the product leads the trend of industry development; meanwhile, the household appliance glass 11 can be promoted to develop towards the direction of energy saving and environmental protection, so that the international market competition position of the Chinese household appliance industry is improved.
