The thread rods, also known as the screw. It is the name of the furniture part in Ming and Qing Dynasties.
The history that people use screw to do transmission is not very long. The traditional screw always has the situation of poor positioning and easy damage. Until 1898, people first tried to put the steel ball between the nut and the screw to replace sliding friction with rolling friction, so as to improve its poor positioning and easy damage. In 1940, the ball screw was placed on the automobile steering device, which was a great revolution in the application of the ball screw, and gradually replaced the traditional acme. Until recent years, ball screw has become one of the most widely used components in the industry. No corresponding standard was found in the national standard, corresponding to DIN 975. The name differs depending on the location. The finger frame is generally set to connect the parts between the legs. The furniture with waist is the main connecting part below the waist. The other parts are generally renamed tooth bars. In addition, it is also used in construction and is most decorated.
