The internal sliding connection of the pipe 1 is connected to an elastic component, which includes a spring 2 6. The left side of the spring 2 6 is fixedly connected to a washer 1 7, and the right side of the spring 2 6 is fixedly connected to a washer 2 8. The washer 1 7 and the washer 2 8. The spring 2 6 provides the necessary elastic force to maintain the correct position and pressure balance of the internal components of the nozzle. The washer 1 7 and the washer 2 8 are fixed to the two ends of the spring 2 6 to protect the spring from wear and ensure uniform transmission of the elastic force.

[0031] Reference Figure 1 , Figure 3, a hole 9 is provided inside the gasket 17, a connecting rod 10 is fixedly connected to the right side of the gasket 17, a plug 11 is fixedly connected to the right side of the connecting rod 10, and the plug 11 is located at the other end of the connecting rod 10, and is used to close a part of the pipe system, blocking and opening the water flow when needed. The top of the pipe 2 12 is fixedly connected to the bottom ring 13, and the top of the bottom ring 13 is fixedly connected to the pipe sleeve 14, which is used to support and fix the pipe sleeve 14. The pipe sleeve 14 is an external structure surrounding the pipe 2 12, which is used to protect the pipe or provide additional structural strength. The top of the bottom ring 13 is fixedly connected to an expandable nozzle 15, which expands or contracts under specific conditions to adapt to different water pressure or flow requirements. The bottom of the bottom ring 13 is fixedly connected to a plurality of fixed rods 16, and the outer portion of the fixed rods 16 is rotatably connected to a limiting rod 17. The limiting rod 17 is rotatably connected to the outer portion of the fixed rod 16, and is used to limit or control the movement of the second pipe 12 to ensure its correct position. The limiting rod 17 is rotatably connected to the interior of the bottom ring 13, and the plug 11 is slidably connected to the interior of the first pipe 1. The two sides of the limiting rod 17 are fixedly connected to the second buckle 18 and the third buckle 19. The interior of the third buckle 19 is provided with a second slide groove 20.
