Spring aka (volume) of spring spiral lines on a plane, the spring is wound into a material plane spiral spring, one end of the spring is fixed, the other end torque after material by bending moment, bending and torsion spring elastic deformation, resulting in its own plane. The deformation angle and torque is proportional to, with high torque, torsional angle and torque is applied to long time work mechanism, is not easy to fatigue properties, the use of similar torsion spring. Clockwork springs have what function? 1, in the limit of the elastic range, the elongation of the spring and the external form. We use this property to spring into spring balance. 2, the spring is under the external force under the action of external force deformation, will be withdrawn, the spring can be restored to the original state. Many tools are the characteristics of the use of spring. 3, have a certain pressure function. We use the stapler has a very long helix spring, it is mainly used as the top tight staples. 4, wind up toy is the application of a spring, when the spring is tightened spring deformation, then the spring energy storage, after being released, the spring force can be converted into kinetic energy, and is driven by the drive device Dongguan Yue in the spring has been adhering to the strict quality management system, each product from design to delivery, quality assurance throughout the system, customers buy not only products, is more of a commitment to the quality of products. Has a group of high-quality staff has always been our pride, we insist on the value of the enterprise, each enterprise is a reflection of the value of employees.
