The other end of the bent pipe 6 is downwardly bent and connected to the sliding assembly. A plurality of second water outlets 7 are formed in the lower surface of the bent pipe 6. The workbench 1 is used to place a workpiece. During machining of the precision carving machine, dust is generated by the workpiece being ground by a cutting head. Most of the dust is concentrated near the workbench 1, part of which falls on the upper surface of the workbench 1, and the other part falls into the dust collecting hopper 3 through the hole of the workbench 1. The water supply assembly is started, and the bent pipe 6 is closed. Water is supplied to the water sprinkling pipe 4 to sprinkle water along the plurality of first water outlets 5, thereby removing the dust in the dust collecting hopper 3. After machining is completed, the cutting head is removed, and the workpiece is unloaded. The bent pipe 6 can be opened and pushed by hand to translate along the sliding assembly above the workbench 1. Water is sprinkled on the upper surface of the workbench 1 by the second water outlets 7 to flush, which can remove the dust on the upper and lower surfaces of the workbench 1, thereby reducing the dust removal dead angle. The waste water with dust enters the dust collecting hopper 3, and the dust is concentrated and discharged along the lower opening of the dust collecting hopper 3, which does not cause obvious dust pollution.
