At first glance, Yuejiu Xi doesn't have much connotation, and the word invention seems far away from him. But it is such an unremarkable person who has developed more than 20 inventions in just two years, many of which have also obtained invention patent certificates.
Yuejiu Xi is a native farmer in Nong 'an County. This year, he has passed the age of no doubt, but he has rich experiences that others can't match. He raised fish, opened a shop and was addicted to racing. It is these experiences that laid a solid foundation for his inventions, making some of his inventions seem ubiquitous, such as game health seasoning, canned lettuce in sugar water, and small emergency power generation rescue vehicles. At present, the State Patent Office has accepted wrist lock device for police riot prevention, waist lock device for police riot prevention, automatic contraction safety traction belt and cardiac rescue. The reason why the invention project is so complicated is because of experience and utility. Many of his inventions borrowed from other existing principles, then redefined the combination and invented many ingenious things. He told reporters about the process of inventing the automatic retractable safety traction belt, which looks as simple as putting an eraser behind a pencil. He has seen many times that when towing a faulty car, because the tractor often brakes, the rear car does not brake, and the traction rope often rolls under the wheel to cause damage. So he invented an automatic telescopic traction rope based on the principle of tape measure. Once the tractor brakes, the rear car will slip for a short time, but the traction rope will automatically rewind, and it will not drag on the ground or roll under the tire.
He has seen many times in the news that when the police stop or arrest drunken armed troublemakers, mental patients and knife-wielding violent elements, they often have direct physical contact with each other with their bare hands, resulting in some policemen being injured and even paying their precious lives. Therefore, it took him only four months to invent a new type of wrist lock device and waist lock device for police riot prevention. According to the principle of ratchet wrench, he made a lock device with trigger mechanism, which looks like handcuffs and has a retractable long rod at the back. If you face a person with a knife, you only need to touch the other person's arm with a knife, which will trigger the mechanism to lock the other person's hand with a knife, so that the other person can't move and protect himself from harm. This device can lock not only hands, but also legs. After locking the leg, the opponent will fall to the ground and lose his resistance. The waist locking device also uses the same principle. This device not only avoids the direct physical contact between the police and the other party in the process of riot arrest, but also greatly reduces the injury of police officers. It can also be used to catch dogs or other animals that hurt people, and it can also be used in rescue sites!
With this faint "money", Yuejiu Xi has gained a lot. Although he has not invented transformation yet, he is full of hope for the future. Like all inventors, his dream is that his invention can truly realize value. Small electric stick
