In addition, the existing positioning tooling has low positioning operation efficiency for large-screen machines, and is inconvenient to adjust the positioning mechanism according to the size of the large-screen machine, resulting in poor compatibility of the tooling. For this reason, we propose a large-screen machine assembly positioning tool to solve the above problems. Utility Model Content
