[0002] An encoder is a device that compiles and converts signals or data into signal forms that can be used for communication, transmission and storage. The encoder converts angular displacement or linear displacement into electrical signals. The former is called a code disk and the latter is called a yardstick. According to the readout method, encoders can be divided into contact and non-contact types. According to the working principle, encoders can be divided into incremental and absolute types. One type is often used in walkie-talkies to adjust the volume or switch channels. However, collisions are inevitable in the use of walkie-talkies. The encoder will also be damaged due to collisions, affecting the normal use of the walkie-talkie. Therefore, a nut fixing structure is proposed. Utility Model Content
