The predecessor of the wrench finger is the ancient so-called "韘" (pronounced shè). "Shuowen" Yun: "Tan, shoot also, so the string." ”
It can be known that the tan is a device designed to protect the fingers when archery is tied to the string.

A wrench is a handguard tool that is attached to a hook string by attaching a finger to hold a bow string. At the same time, when firing arrows, it can also prevent the rapidly retracting bowstring from scratching the fingers. The ancients also called it "machine", which means similar to "trigger", indicating that the role of the trigger finger is equivalent to that of the machine.
