When the laser cutter 16 installed on the limit guide rail needs to be maintained or repaired, the laser cutter 16 is held by one hand, and the pull ring 17 is pulled by the other hand, so that the pull ring 17 pulls the clamp plate 14 from The second clamping plate 14 is no longer matched with the first clamping plate 10 while squeezing and pushing the first spring 13, and the fixing seat 15 is clamped and fixed. At this time, the laser cutter 16 can be removed from the guide rail. When the laser cutter 16 is maintained and repaired, the pull ring 17 is pulled by hand again to open the second clamping plate 14, and the fixing seat 15 is placed between the first clamping plate 10 and the second clamping plate 14. After the position is determined, the hand holding the pull ring 17 is released, and the spring 13 is pushed to push the second clamping plate 14 to the fixing seat 15. The laser cutter 16 mounted on the limit guide rail is clamped and quickly disassembled and installed without using special tools, which shortens the maintenance process, makes the maintenance process simpler, improves the maintenance work efficiency, and further shortens the downtime. When it is necessary to adjust the position of the laser cutter 16 mounted on the limit guide rail, press the cylinder 20 by hand so that the cylinder 20 drives the card 23 to no longer engage with the limit protrusion 18. At this time, the position of the mounting seat 6 can be moved. When the position condition of the mounting seat 6 is good, release the hand pressing the cylinder 20, and the push spring 22 will push the push piece 21, thereby pushing the cylinder 20, and then the cylinder 20 drives the card 23 to engage with the limit protrusion 18 at a different position again, completing the adjustment of the position of the mounting seat 6. By using the positioning device to adjust and fix the position of the mounting seat 6, the limit guide rail can better adjust the position of the laser cutter 16 according to different cutting requirements, so that it can adapt to different cutting requirements, thereby improving the flexibility and adaptability of use.
