[0002] At present, most of the steel strand anchors in flexible photovoltaic power stations are clip anchors. Special tools are required for installation at the construction site. The installation process is complicated and there are certain safety risks, which restricts the construction progress and quality.

[0003] After switching to extruded anchors, one end of the steel strand can be pre-installed at the steel strand manufacturer, which improves the reliability and safety of the anchor, reduces construction costs, speeds up construction progress and improves construction safety.

[0004] During the installation process, the existing extrusion anchors need to reserve a certain length and then use special tools for tensioning. After the installation is completed, the tensioned state of the steel strand is fixed and cannot be adjusted. In the subsequent use process, as the bearing capacity of the steel strand decreases, it is inconvenient to adjust the tensioned state of the steel strand. Therefore, an adjustable photovoltaic steel strand extrusion anchor is urgently needed to solve the problem. Utility Model Content
