[0059] See Figure 1 , Figure 2 , Figure 3 and Figure 4, in this embodiment, the traditional telescopic rod 2 is inserted into the hollow column 1. A cleaning tool (such as a broom or a special-shaped broom) is installed at the top of the telescopic rod 2. The first disc-shaped stud is tightened to fix the telescopic rod 2 in the hollow column 1. By moving the adjustable sliding ring 13 up and down, the adjustable sliding ring 13 is made to push the adjustable upper sliding ring 9 up and down, thereby opening or closing the thermoplastic polyurethane transparent umbrella surface 12 to the required area. The second disc-shaped stud is tightened to fix the open or closed state of the umbrella structure. Through the adjustable upper sliding ring 9, the adjustable lower sliding ring 13, the inner steel skeleton 10, the outer steel skeleton 11 and the lower positioning ring 8, the fan surface is expanded or reduced. The distance between the cleaning tool 18 and the thermoplastic polyurethane transparent umbrella surface 12 is 10 cm to 20 cm. During the cleaning process, dust falls on the inner side of the transparent umbrella surface 12. The operator observes the cleaning position through the transparent umbrella surface 12. At the same time, the transparent umbrella surface 12 has the function of protecting the operator's eyes. If equipment accessories fall into the thermoplastic polyurethane transparent umbrella surface 12 during the cleaning process, it can play a role in isolating and protecting the operator, preventing garbage and dust from falling on the ground for secondary cleaning, saving processes, improving efficiency, and achieving energy conservation and environmental protection without the need for water and electricity.
