This invention discloses a structure with dual-end limiting function, specifically relating to the field of shower head technology. It includes a mounting base with a freely rotatable and anti-detachment rotating sleeve at its bottom. The rotating sleeve has a threaded hole, with a limiting block and a limiting component at each end of the hole. The limiting component includes a sealing plate and a second limiting block that tilts inward towards the threaded spiral structure. A screw is threaded into the threaded hole, with an extension at the top of the screw. A support body rotatably mounted within the mounting base can be linked with the extension via an eccentric shaft-roller, cylindrical spiral rail-pulley, or rack-gear structure. This invention prevents the screw from detaching and avoids axial failure through a dual-limiting structure. The rotating sleeve and screw work together to raise and lower the extension, enabling flexible adjustment of the shower head tilt angle. The rotating sleeve is equipped with ball bearings and anti-slip textures, and the screw, with its special dimensions and thread count design, also features a sliding retainer. This solves the problems of inconvenient adjustment, jamming, and lack of effective limiting in traditional shower head support bases, resulting in smooth adjustment, precise positioning, and safe use.

This utility model discloses a fixing component, including a snap-fit ​​component used in conjunction with an external guide rail. The snap-fit ​​component has a snap-fit ​​groove at its bottom, and symmetrically arranged embedding grooves on both sides of the top of the snap-fit ​​groove, which engage with the top sides of the guide rail. The top of the snap-fit ​​component has a threaded opening, and a sleeve frame is provided on the surface of the snap-fit ​​component. The bottom of the sleeve frame has a sliding groove. This utility model, through the cooperation of the snap-fit ​​component, snap-fit ​​groove, and embedding grooves, can form an upper and lower clamping mechanism for the guide rail, enhancing connection reliability and preventing lateral movement. Then, by rotating a bolt, the snap-fit ​​component is raised and lowered, and the embedding grooves engage with the top of the guide rail, achieving rapid positioning and locking of the fixing component and the guide rail. The operation is convenient and highly stable. Furthermore, the concave design of the sleeve frame allows for precise docking with the external connector busbar, facilitating the integrated installation of electrical components and improving structural compatibility.
