[0037] Embodiment 1:

[0038] Please refer to Figures 1 to 4 as well as Figure 8 It can be seen that in order to enable the device to realize multiple functions and enable the device to have stretching function and magnetic attraction function, the outer protective structure 11 is ultrasonically connected to the outer connecting structure 13 through the internal fixed circular tube 12, and a magnetic ring 14 is sleeved between the internal fixed circular tube 12 and the outer connecting structure 13, so that the outer protective structure 11 can be firmly connected to the internal fixed circular tube 12 and the outer connecting structure 13 through ultrasound, providing preparation for the magnetic attraction function, a threaded connection structure that cooperates with the water pipe connecting structure 3 is provided at the upper end of the outer protective structure 11, a fixed structure that cooperates with the internal fixed circular tube 12 is provided inside the outer protective structure 11, a groove that cooperates with the magnetic ring 14 is provided in the connecting structure of the internal fixed circular tube 12 and the outer connecting structure 13, and the internal fixed circular tube 12 is provided with a snap-fit ​​structure that cooperates with the intermediate connecting structure 2, so that the upper fixed structure 1 can cooperate with the intermediate connecting structure 2, the water pipe connecting structure 3, and the lower fixed structure 4 to realize the magnetic attraction function, the stretching function, and the easy installation function.

[0039] The stretching function is mainly achieved because the two sets of two-end clamping structures 21 are fixedly connected with a bellows 22, and the bellows 22 mainly include metal bellows, bellows expansion joints, bellows heat exchange tubes, diaphragm boxes and metal hoses. Metal bellows are mainly used to compensate for pipeline thermal deformation, shock absorption, and absorption of pipeline settlement deformation, and are widely used in petrochemical, instrumentation, aerospace, chemical, electric power, water conservancy, metallurgy and other industries. The bellows 22 made of other materials such as plastics have irreplaceable roles in the fields of medium transportation, power threading, machine tools, home appliances, etc. The middle connection structure 2 can be stretched through the bellows 22 to provide a stretching function for the device. The clamping structures 21 at both ends are provided with a clamping structure that matches the upper fixed structure 1 and the lower fixed structure 4, so that the middle connection structure 2 can be firmly connected to the upper fixed structure 1 and the lower fixed structure 4 to prevent various problems caused by the stretching process.

[0040] Embodiment 2:

[0041] Please refer to Figure 1 , Figure 5 and Figure 6It can be seen that in order to facilitate the installation of the device while having good filtering ability, the fixed threaded cover 31 is connected to the water pipe connecting cover 33 through the connecting fixed pipe 32, so that the water pipe connecting structure 3 can be conveniently connected to the faucet and firmly connected to the upper fixed structure 1 at the same time, providing the device with a convenient connection function, the fixed threaded cover 31 is provided with a threaded connection groove on the outside, and the water pipe connecting cover 33 is provided with a threaded connection groove on the inside, and the fixed threaded cover 31, the connecting fixed pipe 32, and the water pipe connecting cover 33 are provided with a water flow groove inside, and the fixed threaded cover 31 and the water pipe connecting cover 33 are provided with a friction structure, so that the water can flow and be firmly connected to each component at the same time;

[0042] The filtering function is realized because an array of upper magnetic blocks 42 are fixedly arranged on the upper end of the bottom fixed shell 41, an internal filtering structure 43 is plugged into the bottom of the bottom fixed shell 41, and the bottom fixed shell 41 is connected to a bottom fixed cover 45 through a bottom water outlet plate 44, so that the various components of the lower fixed structure 4 are firmly connected, providing a basis for the realization of the filtering function, a connecting groove matched with the upper magnetic block 42 is provided on the upper end of the bottom fixed shell 41, a plug-in groove matched with the internal filtering structure 43 is provided inside the bottom fixed shell 41, and threaded grooves matched with each other are provided on the bottom fixed shell 41 and the bottom fixed cover 45, so that the lower fixed structure 4 can realize the filtering function through the internal filtering structure 43, so that the functionality of the device is further expanded;

[0043] The bottom fixed shell 41 is made of a transparent material, so that the use of the device is clear at a glance and convenient for observation, and the material of the bottom fixed shell 41 can be polycarbonate PC: PC plastic has extremely high impact strength and excellent transparency, and is a very strong transparent plastic. It can withstand large forces without breaking, and has strong UV resistance and is not easy to turn yellow. PC plastic is often used to manufacture products such as safety glasses, bulletproof glass, and mobile phone screen protectors. Polymethyl methacrylate PMMA, also known as acrylic: PMMA plastic has excellent optical properties and transparency, is lighter than glass, and is easy to process and shape. Although it is not as good as PC plastic in impact resistance, it performs well in weather resistance and chemical stability. PMMA is widely used in display racks, lamps, windows, decorative panels, etc. Polyvinyl alcohol PVA: PVA is a highly soluble plastic with very high transparency and good tensile strength. It is usually used to make high-transparency packaging films, coating films, and some special-purpose film products. Polystyrene PS: PS plastic has high transparency and is easy to process and shape, but is relatively inferior to PC and PMMA in impact resistance and heat resistance. It is mainly used to make food packaging, transparent containers, optical lenses and other products. Polyethylene PE: Under certain conditions, PE can also be made into transparent plastic materials, such as polyethylene film or transparent PE sheet. PE has good chemical corrosion resistance and electrical insulation properties, and is widely used in some specific fields.

[0044] Working principle: The device can be used by installing it on the faucet through the water pipe connecting structure 3. It is very convenient. When it needs to be stretched, the stretching effect can be achieved through the middle connecting structure 2 by pulling the lower fixed structure 4. When it needs to be contracted, the magnetic adsorption of the lower fixed structure 4 and the upper fixed structure 1 can quickly correspond to the contraction. During use, if the internal filter structure 43 is found not clean enough through the bottom fixed shell 41, the internal filter structure 43 can be replaced by twisting the bottom fixed cover 45, which is very convenient.
