Garden tools are now widely used and come in a different category. Pole saws are used to cut tall branches, so people don't have to cut branches at high altitudes. However, according to the research results, some problems need to be solved. First of all, the falling sawdust always causes trouble to the user when cutting. Secondly, people feel tested when they hold the pole saw for a long time due to weight problems. A transparent umbrella-shape cover was designed to help protecting people when they are cutting the branches.
