More specifically, it is an extension that can facilitate construction and pushing carpets and absorbing floor tiles. Auxiliary | [Previous technology] According to the prior knowledge, the laying of the carpet needs to be flat and no wrinkles appear. Once wrinkles are present, it is often difficult for the construction staff to straighten them, and they need to perform straightening and flattening from each corner of the wall. However, it is not easy to straighten and flatten by human hands, so a push assist appears on the market, mainly with a head with claws and a handle for hand grip. A person holds the handle or a human knee. Hold the end of the handle and push the claws of the head, and the claws grasp the carpet for the action of flattening and straightening the carpet. Because of its labor-saving and efficient, the construction personnel are much more convenient (such as attachment No. 009. As shown in No. 205494); However, due to the very limited length, this tool is not easy to operate when it encounters corners or places where the human body cannot reach, and the head is bulky and difficult to store The large size of the package is its disadvantage, and each of the construction workers has different heights. When squatting down, press the knee against the end of the handle. It varies from person to person, and there is no proper angle to push with effort, so it also causes male and female construction staff to contribute Different, the construction is more laborious. In view of this, based on the above-mentioned shortcomings, the creator of this case is still actively working on development, research and improvement, and has accumulated many years of manufacturing and production experience, and finally there is a creation that is sufficient to solve the above shortcomings.
