As shown in the picture, I want the path to keep a certain distance from obstacles, how to do it?

Hi

Typically, you either increase the erosion iterations or collision checking diameter on the grid graph. In your case, you may also want to reduce the amount of smoothing done by the SimpleSmoothModifier.
