Under the existing technical conditions, when spraying wear-resistant coating on a dispersed blade, in order to ensure the uniformity and precision of the coating, it is often necessary to use shelter tooling to shield the non-spraying area. However, these shelter toolings will inevitably generate friction during installation and removal.

[0003] This lapping and friction not only causes wear on the surface of the shelter tooling. Over time, the wear will gradually accumulate. This not only affects the appearance of the tooling, but more importantly, it also destroys the original dimensional accuracy and shape accuracy of the tooling. Once these accuracy indicators cannot meet the requirements, the sheltering effect of the tooling will be greatly compromised.
