Ruler fixture with magnetic detection function

Abstract

A ruler-attaching fixture with magnetic detection function includes a fixture body and a magnetic field sensor. The fixture body has a first support portion and a second support portion disposed on opposite sides and spaced apart. The magnetic field sensor is integrated into the fixture body. During the process of the user operating the fixture body to attach the magnetic ruler to the surface of a platform or slide, the magnetic field sensor simultaneously senses the magnetic field of the magnetic ruler passing through the first support portion and the second support portion, thereby checking whether the magnetic poles of the magnetic ruler are abnormal or damaged, thereby improving the convenience of the ruler-attaching operation.
