“防止结合处变形断裂钳子”的发明人是张春玉。是ZL- 2016 2031991109 9号中国实用新型专利证书可证明的。

The inventor of "pliers for preventing deformation and fracture at the joint" is Zhang Chunyu. It can be proved by ZL - 2016 2031991109 Chinese utility model patent certificate.

张春玉，1953年生人，曾做过黑龙江省笔架山监狱农机科长，农机修造厂厂长，大连吉发机械厂技术顾问。

Zhang Chunyu, born in 1953, once served as the director of the agricultural machinery section of Bijiashan prison in Heilongjiang Province, the director of the agricultural machinery repair and manufacturing factory, and the technical consultant of Dalian Jifa machinery factory.

张春玉从16岁上班工作就在笔架山修造厂做车工，与机械打交道。后来被保送到八一-农垦大学学习农机专业。在校学习期间就曾因学习刻苦 ，又有6年的修理农机经验，在大-实习组装发动机时发现了收割机发动机曲轴有立碴裂痕而避免了一次重大机械事故，受到老师的重视和学校的表杨。

Zhang Chunyu has worked as a lathe worker in Bijiashan repair and manufacturing factory since she was 16, dealing with machinery. Later, he was sent to Bayi Agricultural Reclamation University to study agricultural machinery. During my study in school, I worked hard and had 6 years of experience in repairing agricultural machinery. When I assembled the engine, I found that there was a slag crack on the crankshaft of the harvester engine, which avoided a major mechanical accident. I was valued by the teacher and praised by the school.

张春玉对专业的学习也都非常认真，现在回想到那时学的机械原理，材料力学还能说出老师当年讲的要点:只要有接触，就有力的作用，我们的工作，就是找出受力点和计算出材料的应力，然后给出相应的材料。

Zhang Chunyu is also very serious about her professional study. Now looking back on the mechanical principles she learned at that time, material mechanics can also tell the key points that the teacher said in those years: as long as there is contact, it will play a powerful role. Our work is to find out the stress point and calculate the stress of the material, and then give the corresponding material.

后来在工作中看到德国雷肯公司大犁，一台机械能连续使用几年也不出现故障，而我们国产的同类机械使用不长时间就有毛病，细究原因，一是设计时就有缺陷，属胎里坏，再一条原因就是材料不过关。在农机修造场和农机科，就因多次对大豆精量点播机，水稻苗床人工播种机、悬挂深松进行技术革新而被上级部门和省农机管理部]评为技术革新先进标兵。

Later, I saw the plough of German rayken company at work. A machine can be used continuously for several years without failure, while our domestic similar machines have problems after a short time of use. After careful investigation, one is that there are defects in the design, which is bad in the tire, and the other is that the materials are not qualified. In the agricultural machinery repair yard and agricultural machinery department, because of many times of precision soybean on-demand planter, rice seedbed artificial planter and suspension planter Hang Shensong carried out technological innovation and was] rated as an advanced model of technological innovation by superior departments and provincial agricultural machinery management department.

退休后依然兴趣不减，到大连定居后，一-次在大连博物馆看到中国第一台高 压氮气压缩机，很有感触。又勾起了他探索改进中国机械的想法。巧合的是那些天他帮儿子修理一台机器，用钳子拧一个生锈的螺丝时，掰坏了一把钳子，也没拧动，换了把钳子，又掰断了钳口，他记起原先在工厂用钳子掐钢丝也经常断钳把，这些现象让张春玉琢磨了起来。他从钳子的断口处和两扇钳把的结合处开始分析，发现了两个因素:一个是 受力结构不合理，再一个是材料不过关。 他至今还记得当年在学校时教力学的王泰恩老师的教导:我们来上大学，不是要学会做某一种机械和产品，而是要学习如何发现问题和解决问题的能力，发现问题，就解决了问题的一半。

Still interested after retirement, after settling in Dalian, I saw China's first high-pressure nitrogen compressor in Dalian Museum for the first time. It also aroused his idea of exploring and improving Chinese machinery. Coincidentally, those days he helped his son repair a machine. When he screwed a rusty screw with pliers, he broke a pair of pliers and didn't screw it. He changed a pair of pliers and broke the jaws. He remembered the original In the factory, when pinching steel wire with pliers, the pliers handle is often broken, which makes Zhang Chunyu ponder. Starting from the fracture of the pliers and the joint of the two pliers handles, he found two factors: one is the unreasonable stress structure, and the other is the poor material. He still remembers the teaching of Mr. Wang taien, who taught mechanics in school: we don't come to college to learn to make a certain kind of machinery and production Product, but to learn how to find and solve problems. Finding problems solves half of the problems.

发现了钳子的问题，张春玉就开始着手进行改进。他从力学的受力角度对两扇钳把的结合角度进行了改进。又通过同学关系搞到了一块做钳子用的特殊材料。自己设计了图纸又找到个体机械加工厂亲自指导进行加工。最后经过多次试验，感觉比现在市场上的钳子耐用了几倍。

When the problem of pliers was found, Zhang Chunyu began to improve it. He improved the combination angle of the two pliers handles from the point of view of mechanical stress. Through the relationship with students, I got a special material for pliers. I designed the drawings and found an individual mechanical processing factory to personally guide the processing. Finally, after many tests, I feel that it is several times more durable than the pliers on the market.

他知道，搞科学得用数据说话，于是带着他的产品找到了大连理工学院的力学研究室请他们帮助检验测试。

He knew that science had to use data, so he took his products to the Mechanics Laboratory of Dalian Institute of technology and asked them to help with inspection and testing.

测试后效果非常理想，主持试测的老师告诉他这个改进成果，在国内应用工具中还属空白，可申请专利，并愿做专利申请代理。

After the test, the effect was very ideal. The teacher who presided over the test told him that this improvement achievement was still blank in domestic application tools. He could apply for a patent and was willing to be a patent application agent.

2016年2月国家专利局审核批准了张春玉的“防止结合处变形断裂的钳子”的专利。专利功能是这样介绍的:本“实用新型"专利是在不改变钳子外形和使用功能基础上,改进钳子互簌结构产生应力集中，易导致钳子变形甚至损坏缺陷，提高钳子整体强度和使用寿命。此专 利技术对企业是发展创新，并具有广泛市场前景能产生-定社会效益。张春玉知道，他这项发明，是他做一个更大发明的热身与铺垫，从中了解发明的程序与有关部i衔接的过程。他正在着手准备一 个更大的发明项目，这个项目如能搞成功，则是一项功在当代，受益世界的发明，通过应用他的发明成果，将从节约能源和减少大气污染两方面让人类受益。

In February 2016, the State Patent Office examined and approved Zhang Chunyu's patent of "pliers for preventing joint deformation and fracture". The patent function is introduced as follows: on the basis of not changing the shape and use function of the pliers, the patent of the "utility model" improves the mutual rustling structure of the pliers, resulting in stress concentration, which is easy to cause deformation and even damage defects of the pliers, and improves the overall strength and service life of the pliers. This patented technology is a development innovation for enterprises, has broad market prospects and can produce certain social benefits. Zhang Chunyu knows that his invention is a warm-up and foreshadowing for him to make a greater invention, from which he can understand the process of connecting the invention procedure with the relevant departments I. He is preparing a larger invention project. If this project can be successful, it will be an invention that benefits the world in the contemporary era. Through the application of his invention achievements, mankind will benefit from saving energy and reducing air pollution.

因为这项专利正在研制过程中，笔者不能泄露商业机密。还能告诉读者的是为了这项发明，张春玉已经用半年多时间查阅了国际上有关专家的理论书籍。进行了多次的理论测算。从理论上证明了他的想法可行。他目前正在寻找能为他提供实际操作试验的伙伴。

Because this patent is under development, the author cannot disclose trade secrets. What can also tell readers is that for this invention, Zhang Chunyu has spent more than half a year consulting the theoretical books of relevant international experts. Several theoretical calculations have been carried out. His idea proved feasible in theory. He is currently looking for partners who can provide him with practical experiments.

到手的专利证书让他看到了前景与希望。

The patent certificate he obtained showed him the prospect and hope.
