[0011] The semi-automatic laser welding mechanism for mounting columns provided by this utility model has low human intervention during the welding process. The positioning and pressure of the mounting column are controlled by the mechanism, resulting in high accuracy and stable quality. After debugging, there will be no situation where the quality is inconsistent. The welding accuracy is determined by the accuracy of the mechanism when the mounting column is placed manually, resulting in accurate welding and a low defect rate. Attached Figure Description
