When in use, the fixing device is mounted on the laser cutting head, and the turntable is rotated. The screw drives the two sets of connecting blocks and the fixing rings to approach each other to fix the anti-collision structure on the laser cutting head, which is convenient for adapting to laser cutting heads of different sizes. Then, the laser cutting head is started. When the laser cutting head collides with the cutting object during movement, the anti-collision baffle rotates toward the laser cutting head under the squeezing of the cutting object, thereby triggering the control panel through the contact sensor, and then stopping the movement of the laser cutting head, reducing the phenomenon that the connecting parts of the laser cutting head may be tilted and broken due to impact, thereby causing damage to the laser cutting machine.
