[0002] Flexible welding is operated by a multi-axis robot, which can flexibly adapt process parameters and processing paths according to different welding processes and requirements. In order to facilitate welding work on the workpiece, it is often necessary to use a flexible welding tool to fix it. The utility model patent with patent application number CN202022507600.0 discloses a diversified flexible welding tool. Support legs and support feet are designed on both sides of the column to avoid the inconvenience of adjusting the height of the device according to the usage situation during use, making it inconvenient to operate the welding tool at a higher or lower position.
