Connection converter for measuring stability of orthodontic anchorage nail through resonant frequency analyzer

The invention discloses a connection converter for measuring the stability of an orthodontic anchorage nail by a resonant frequency analyzer, belongs to the technical field of medical instruments, and solves the problem that a transducer of an existing resonant frequency analyzer cannot be directly connected with the anchorage nail. The chuck comprises a chuck shaft and a chuck sleeve, the chuck shaft is arranged in the chuck sleeve, and the chuck shaft and the chuck sleeve are connected through threads to ensure tight combination; one end of the chuck shaft is provided with an internal thread matched with an external thread of the transducer, the other end of the chuck shaft is an elastic chuck composed of six clamping pieces, and a hexagonal chuck hole matched with the hexagonal prism neck of the anchorage nail is formed in the elastic chuck. By forming a stable transducer-converter-anchorage nail system, a feasible thought is provided for applying resonance frequency analysis to clinic, and a clinician can
