[0002] During maintenance work, operators often need to perform aerial work. At this time, the personal safety of the operator must be ensured. A common practice is to use a safety rope. The safety rope must be firmly fixed to the installation and fixing structure to ensure safety. Generally, a bracket is welded on the mounting and fixing structure, and the safety rope is fixed with the bracket. However, this method has disadvantages: First, the bracket must be cut off after the safety rope is used, and the mounting and fixing structure will be damaged during the removal of the bracket. Second, because the bracket is welded to the mounting and fixing structure, it cannot be moved. When the safety rope is in position, the bracket must be re-welded to the new location to fix the safety rope, which is inconvenient to use.
