[0030] Embodiment 2

[0031] On the basis of the first embodiment, in order to achieve dust reduction of the laser cutting machine body 1, the water pipe 2 is fixed on the surface of the laser cutting machine body 1, the water pump 3 and the laser cutting head 4 are fixed on the surface of the laser cutting machine body 1, the guide rod 10 is sleeved with a spring 7 on the arc surface, due to the elasticity of the spring 7, the spring 7 resets and pushes the sliding block 22 to move, so that the stopper 23 moves to the notch of the positioning groove 17, so that the baffle 19 cannot rotate, the inner surface of the sliding block 22 is fixed with a rotating shaft 21, the positioning rod 6 is sleeved on the surface of the rotating shaft 21, the end of the positioning rod 6 is fixed with a stopper 23, and the arc surface of the water pipe 2 is provided with a positioning hole 13;

[0032] There are multiple groups of positioning grooves 17, which are circumferentially distributed on one side of the rotating block 8. There are multiple groups of stoppers 23, which are circumferentially distributed. The stoppers 23 correspond to the positioning grooves 17. The stoppers 23 are clamped in the positioning grooves 17, and the two are movably connected to limit the rotation range of the rotating block 8, so as to facilitate the control of the state of the baffle 19.

[0033] The size of the positioning groove 17 is the same as that of the stopper 23, the size of the notch 18 is the same as that of the positioning rod 6, and the size of the stopper 23 is larger than that of the positioning rod 6, and the stopper 23 is stuck in the positioning groove 17, so the stopper 23 will not be separated from the positioning groove 17, and the positioning rod 6 will not be separated from the positioning groove 17;

At this time, the water pump 3 is started, and the water pump 3 will drive the water in the water tank 5 to spray to the position of the laser cutting head 4 in the form of water mist, so as to prevent the dust generated during cutting from flying, thereby realizing the dust reduction of the laser cutting machine body 1. This structure is simple and easy to operate, which is conducive to improving its use effect.
