Abstract: Disclosed herein are an installation assembly (1), an instrument (2) and an installation method for a radio frequency identification tag. The installation assembly (1) comprises a first housing unit (11) mounted on the instrument (2) and a second housing unit (14) snapped-fitted with the first housing unit (11) to form a receiving space for receiving the radio frequency identification tag (13). The radio frequency identification tag (13) can be easily installed on the instrument (2) by snapping-fitting the first housing unit (11) with the second housing unit (14), thereby effectively enhancing installation efficiency and reliability of the radio frequency identification tag (13).
