Technical Field
[0001] The utility model belongs to the technical field of grass rakes, in particular to a novel combined grass rake. Background Art
[0002] Trees or shrubs generally sprout and start growing in spring. When the weather gradually gets colder in autumn and winter, trees begin to shed their leaves. At this time, it is necessary to clean up the fallen leaves and dead grass. Grass rakes, as the name implies, are used for raking grass. They are roughly similar in appearance to the nail rakes used by Zhu Bajie, but not as delicate. They used to be made of bamboo or wood, but now they are also made of iron and stainless steel. At present, the styles of grass rakes on the market are quite diverse, some are dense and some are sparse. When using grass rakes to rake fallen leaves or dead grass one by one, it is often necessary to use a denser grass rake to rake again because the grass rake is too sparse. Repeating this raking method requires workers to work for a long time and their arms will ache, which increases labor costs and wastes a lot of time. For this reason, we propose a new type of combined grass rake. Utility Model Content
