[0002] In the design and manufacturing process of small airplanes, the fuel selector support is a crucial component that is responsible for supporting and fixing the fuel selector to ensure accurate and reliable selection of the required fuel source during flight. Currently, most small airplane fuel selector supports on the market are made of metal structures and assembled through welding or bolt connection. These supports can meet the basic support and fixing requirements to some extent.
[0003] However, when these supports are fixedly installed on external frame bodies, they are usually directly fixed with fastening bolts. Since the supports are made of metal structures and the corresponding external frame bodies are also made of metal structures, there are no corresponding force relief and buffering components between the metal and metal, which cannot perform certain buffering and shock absorption protection operations. Direct rigid connection can easily cause the external frame bodies to transmit force directly to the supports after being stressed, which can adversely affect the supports and the installed components on the supports, further affecting the service life. In view of this, we propose a small airplane fuel selector support. SUMMARY
