Abstract

La présente invention concerne une structure de fixation pour un capteur qui comprend une plate-forme formée par l'extrémité avant du capteur. Une cavité est située près du côté de sous-face de la plate-forme, un trou traversant est situé au niveau du côté d'extrémité supérieure de la plate-forme, ledit trou traversant connectant la cavité. Une pièce coulissante correspond à la cavité et peut coulisser dans la cavité. Un trou de came est situe sur la surface de la pièce coulissante, et son extrémité avant est plus étroite tandis que la partie arrière s'élargit progressivement. En outre, un écrou de vis est inséré dans le trou traversant, et ledit écrou de vis correspond à un boulon.
