However, traditional railing crossbar assembly and fixing methods have significant limitations: Firstly, existing fixing clamps are mostly designed with a single specification, only suitable for crossbars of specific sizes. When project requirements involve aluminum alloy crossbars of different diameters and cross-sectional shapes, it is necessary to frequently change the type of clamp, leading to a significant increase in construction costs and a high rate of clamp idleness, resulting in serious resource waste. Secondly, the traditional clamp installation process is cumbersome, often relying on bolt tightening and welding, which not only consumes a lot of time and manpower but also requires a high level of technical proficiency from construction workers, resulting in low installation efficiency and making it difficult to meet the fast-paced construction of modern building projects.

The sliding groove 61 has a slider inside, which facilitates the extension and retraction of the two clamping blocks 7. The upper surface of the slider is fixedly connected to the clamping block 7. There are two symmetrical sliding grooves 61 for facilitating the clamping of the crossbar. The clamping block 7 is L-shaped, and the inner side of the clamping block 7 is set as an arc surface. There are two symmetrical clamping blocks 7 for clamping crossbars of different shapes and sizes. A tension spring 71 is set between the two clamping blocks 7. The two ends of the tension spring 71 are fixedly connected to the slider to ensure that the crossbar remains firmly clamped.

[0017] Specifically, the support base 1 is in the shape of an inverted T, and mounting holes are provided on both sides of the support base 1 to enhance its own stability and facilitate fixing to other fixed objects. A rotating block 4 is fixedly connected to the upper surface of the rotating sleeve 9.
