[0017] In an optional embodiment, it also includes an adjusting component, which is used to drive the two groups of semi-annular liquid spraying branches 1 to move toward or away from each other.

[0018] On the one hand, the distance between the two semi-annular liquid spraying branches 1 can be adjusted so that the nozzles 11 in the two semi-annular liquid spraying branches 1 can be adapted to spray cutting fluid on piston ring grooves of different sizes;

[0019] On the other hand, a gap may be provided between the two semi-annular liquid spraying branches 1 so that the two semi-annular liquid spraying branches 1 can be inserted into the piston ring groove 3 for processing.
