[0002] Nowadays, the sanitation workers who sweep the streets in cities use bamboo brooms made of traditional bamboo branches. When used, they raise a lot of dust, have poor coverage on leaves or scraps of paper, and need to sweep up floating, flowing, and lightweight objects. They often have to repeat the sweeping action several times to achieve the goal, which increases the labor intensity and reduces the cleaning efficiency. The dust also has an adverse effect on the respiratory system of sanitation workers. During the cleaning process, a bamboo broom will gradually become sparse, making the cleaning area smaller and smaller. The probability of having to re-tie this bamboo broom two to three times a day is quite high, which also increases the workload of sanitation workers in disguise. Utility Model Content
