According to related news, this happened in Jinzhou, Liaoning. The grandfather who invented the new glass wiper device developed this simple and practical glass wiper after four years of research and study. From his own words, we can know that because his friend is specialized in cleaning glass, the glass wiper is always easy to fall off during work, and the falling glass wiper will be attracted to the edges and corners of iron objects because of the strong magnet attraction, which is difficult to take off, which greatly affects the work progress.
It is precisely because this uncle always likes to do some small research and inventions that his friends will ask him for help, hoping to solve this problem. After he went to the scene to watch, he also found that the magnet was particularly attractive. If you accidentally drop it, it will be really difficult to continue working. After careful investigation and study, Uncle resolutely developed a new type of glass cleaning device.
This uncle said it himself. In the process of research, thousands of external models of glass wipers were changed, and the right one was found after many experiments. Grandpa finally completed the glass wiper, which was not only pasted firmly, but also had a special unlocking device. Just press the glass wiper gently, and it will stick or fall according to the user's intention.
I have been engaged in cleaning glass before. In the process of working, the glass cleaner is really vulnerable to friction and dust, and it is difficult to take out the magnet after it is accidentally stuck on the iron block. The uncle's invention is simple and practical, taking into account the real situation, which deserves everyone's recognition.
