The hollow net frame is a structural design and consists of a plurality of hollow pipes which are connected with each other to form a grid-shaped frame structure. Such structural designs are commonly used in the construction of large buildings such as roofs of buildings, exterior walls of buildings, underground garages, and stadiums. The hollow net frame has high strength and stability, light weight and good ventilation performance, so that the hollow net frame is very suitable for large-span building structures.

Hollow wire frames are typically constructed of a plurality of hollow tubes connected together by node connectors. Node connectors are a special component, typically made of steel or aluminum, that can connect together a plurality of hollow tubes to form a grid-like frame structure. When one node connector connects a plurality of hollow tubes, it is necessary to accurately align them with the connection holes of the node connector. Since the position of the connection hole and the diameter of the hollow tube need to be matched, the positional accuracy of the connection is difficult to ensure.
