[0043] Working principle: When using a fire-fighting robot to extinguish a fire, the second fixed seat 8 will show the on-site situation to the firefighters. At this time, the water pipe 9 is connected to a fire hydrant or other water storage devices. The nozzle 7 will cooperate with the water pipe 9 to spray water at the fire for extinguishing. When the nozzle 7 needs to be replaced, loosen the rotation knob 17 by hand, so that the rotation knob 17 drives the extrusion block 16, so that the extrusion block 16 no longer extrudes the driving block 11. At this time, the pushing spring 12 will push the driving block 11, and the driving block 11 will also drive the clamping strip 15 through the second fixing column 14, so that the clamping strip 15 is separated from the clamping groove 10. At this time, the nozzle 7 can be replaced and maintained. Place the new nozzle 7 or the maintained nozzle 7 to the original position through the second fixed seat 8, and make the clamping strip 15 and the clamping groove 10 at the same horizontal level. At this time, rotate the rotation knob 17, so that the rotation knob 17 drives the extrusion block 16 to extrude the driving block 11. After being extruded, the driving block 11 will drive the clamping strip 15 through the second fixing column 14, so that the clamping strip 15 is re-engaged with the clamping groove 10. By driving the clamping strip 15 to engage and disengage with the clamping groove 10, the nozzle 7 can be quickly replaced, shortening the time required for maintaining and replacing the nozzle 7 and improving the efficiency of maintenance and replacement.

[0044] When the water pipe 9 needs to be wound up, start the collecting roller 19. The collecting roller 19 will rotate and wind up the water pipe 9 when rotating. The second motor 21 will drive the driving strip 22 to rotate, so as to drive the rotating piece 20 to swing through the driving convex block 23. When the rotating piece 20 swings, it will also guide the water pipe 9 through the guide 24, so that the water pipe 9 is wound up on the collecting roller 19 more evenly, avoiding the phenomenon that the water pipe 9 is excessively wound locally.
