[0029] The adjustment platform 3 includes an adjustment plate 301 and two bottom support plates 302 located below the detection plate 4 . Two gaskets 303 are arranged between the bottom of each bottom support plate 302 and the adjustment plate 301 . The bottom support plates 302 and the detection plate 4 are fixed by bolts 9 .

[0030] The adjustment assembly 8 includes an adjustment screw 801, the bottom of which is connected to the moving plate 1, the upper part of which passes through the adjustment plate 301 and the gasket 303 and is connected to the bottom support plate 302, and an adjustment nut 802 is provided on the adjustment screw 801 below the adjustment plate 301. The adjustment screw 801 passes through the upper and lower outer surfaces of the adjustment plate 301 and the gasket 303 and is provided with threads. The adjustment assembly 8 is provided with four groups, which are respectively arranged around the moving plate 1 and the adjustment plate 301 near the edges. Specifically, the adjustment nut 802 is a butterfly nut, and the gasket 303 is a circular gasket.

[0031] Each group of the laser devices 5 includes a laser mounting platform 501 and a laser instrument 502 arranged on the laser mounting platform 501.
