[0002] As the overall competitiveness of the photovoltaic industry becomes increasingly fierce, each company aims to save costs but ignores safety, resulting in safety problems due to loose connection nodes.

[0003] At present, traditional purlin connectors use two independent connectors to fix the diagonal braces and columns. If the gap between the two hoops is too large, the root stress will increase. The longer the time, the more likely it is to have cracks and damage the acceptance mechanism. If the gap between the two hoops is too small, the fastening force will be insufficient, thus posing a safety risk. Therefore, the connection method using two independent hoops for connection has unstable factors and the force transmission path is not clear enough. Utility Model Content
