[0002] Shower heads are commonly used devices for controlling water discharge in our lives. Since overhead shower heads are more comfortable to use for flushing, they have become an indispensable design in shower heads. Since overhead shower heads are installed at different heights, the water pipe design in the shower head must also be adjusted to adapt to the installation height of the overhead shower head. The water pipes in existing shower heads mostly adopt a multi-section design, that is, they are connected in the form of multiple sections of water pipes to meet the requirements of different installation heights of overhead shower heads. However, the existing structural design not only occupies packaging space and volume during packaging, wasting packaging resources, but also the multi-section design also causes the overhead shower to withstand limited water pressure, and the connection is prone to movement after long-term use. Therefore, the structural defects existing in this aspect of the shower head structure need to be further improved and optimized. Summary of the Invention
