According to the design of the screw washer 110 , when the metal piece 120 and the metal piece 130 are disassembled, after the screw 100 is loosened, the screw washer 110 is often easily dropped or lost, causing trouble for maintenance. Especially when replacing parts at the user end, if the screw washer is loose, it cannot ensure that the user can install it correctly; if the screw washer is lost, it is necessary to purchase new parts, causing a lot of inconvenience.

Most of the existing belts control the length of the belt by fixing the other end of the belt by the buckle, and the period that is often buckled by the buckle will be deformed and damaged after long-term use, and the user may change the position from standing to sitting or after meals. The circumference of the belt can be adjusted, and micro-adjustment is not necessarily possible when adjusting the tightness of the pin buckle type or buckle plate type belt buckle. In order to solve this problem, it is necessary to design a belt that is relatively suitable for the waist of a person.

Standards are norms, and each country and sector has its own standards. The most commonly used standards in our daily business are as follows: GB—China National Standard (National Standard) ANSI—American National Standard (American Standard) DIN—German National Standard (German Standard) ASME—American Society of Mechanical Engineers Standard JIS - Japanese National Standard (Japanese Standard) BSW - British National Standard GB - National Standard is one of many standards in my country, as well as industry standards, professional standards and department standards. National standards are divided into: GB (mandatory standards) and GB/T (recommended standards) and GBn (national internal standards) and so on. We usually see GB30, GB5783, etc. are mandatory standards. In addition to some basic dimensions such as head-to-side, head thickness, etc., the above standards are mainly different in the threaded part. The threads of GB, DIN, JIS, etc. are all in MM (millimeters), which are collectively referred to as metric threads. Another thread like ANSI, ASME, etc. is called American standard thread in inches. In addition to metric threads and American threads, there is also a BSW-imperial standard, whose threads are also in inches, commonly known as Wyeth threads.
