[0002] During the installation of building curtain walls, fasteners are an indispensable connector used to fix curtain wall panels to the main body of the building. However, existing fasteners have some shortcomings. For example, fasteners have a poor fixing effect on building curtain walls, and nuts will rust due to the influence of the external environment, which affects the service life and safety of the curtain walls.

[0003] The prior art has the following problems:

[0004] 1. When the existing fasteners are used to fix the building curtain wall, bolts are used to fix the building curtain wall. However, due to the small force area between the fastener and the building curtain wall, when the handle is used to apply pressure to the fastener, the contact area pressure between the fastener and the building curtain wall will gradually increase. When the pressure on the building curtain wall is too large, the building curtain wall will be damaged, thereby reducing the fixing effect of the fastener on the building curtain wall;

[0005] 2. In the actual use of existing fasteners, as the service life of the fasteners is extended, the nuts that fix the fasteners will rust due to the influence of the external environment. When the nuts are rusted, it will be inconvenient to disassemble the fasteners, thereby reducing the convenience of disassembly and assembly of the fasteners. Therefore, a special-shaped fastener for building curtain walls is proposed. Utility Model Content
