Specifically, the spray assembly includes: a horizontal support plate 9, two vertical mounting plates 10, two laval nozzles 11 and two lasers 12. The horizontal support plate 9 is disposed on the upper surface of the frame 1 below the first slider 6 so that the horizontal support plate 9 does not restrict the movement of the first slider 6. The two vertical mounting plates 10 are oppositely arranged in parallel. The lower ends of the two vertical mounting plates 10 are respectively connected with the upper surfaces of the left end and the right end of the horizontal support plate 9. The left and right of the horizontal support plate 9 according to the embodiment of the present invention refer to the left and right direction as shown in fig. 5.
