The utility model has the advantages that:
1, laser beam can be converged, make the shape of its hot spot more regular;
2, this device powder feeding point distance is adjustable, and adjustable distance is 0～10mm;
3, the focal length of this device is adjustable, and adjustable distance is 0～8mm;
4, evenly powder feeding because this device adopts four direction powder feeding simultaneously, guarantees the homogeneity of powder sending quantity to a certain extent;
5,, effectively prevented owing to the reflection of the laser powder curing phenomenon that causes of being heated produces in cavity to the dual water-cooling system in powder feeding chamber;
6, prolong the work-ing life of mirror, adopt water-cooled and two-sided air cooling system,, also kept the cleaning of minute surface simultaneously the lens cooling.
