[0026] In this embodiment, first, a rotary workpiece whose outer surface needs to be sprayed is placed between the upper sealing plate 9 and the lower sealing plate 5. Then, spraying liquid is pumped into the spraying pipe 10. The spraying liquid sprays out from the spraying holes 11 along the pipe and is sprayed onto the surface of the workpiece. During this period, hold the driving rod 8 and apply downward pressure to change the axial position of the workpiece. With the spraying of the low-density spraying holes, the effect of uniform spraying can still be achieved.
