As shown in fig. 2, specifically, the spraying mechanism 12 includes a spraying member 121, a fixing column 122 and an adjusting beam 123, the fixing column 122 is fixed on the worktable 11, one end of the adjusting beam 123 is adjustably disposed on the fixing column 122 in the horizontal direction X, the adjusting beam 123 is connected with the fixing column 122 by a protrusion-groove structure, the protrusion of the fixing column 122 can move in the groove of the adjusting beam 123, and thus the adjusting beam 123 can be adjusted in the horizontal direction X relative to the fixing column 122.

The spraying piece 121 is arranged at the other end of the adjusting beam 123 in a vertically adjustable manner, and the spraying piece 121 is vertically inserted into the adjusting beam 123 and can be vertically adjusted in the insertion hole of the adjusting beam 123, so that the adjusting of the adjusting beam 123 in the vertical direction Y is realized.
