Abstract: A buckle device capable of displaying a locked state includes a main body unit, a latch unit, a fastening unit, an electromagnetic unit, and a control unit. The main body unit includes a main body and the latch unit includes a detachable tongue element. The fastening unit includes a bolt body interfering with the tongue element. The electromagnetic unit includes an electromagnetic module and an electromagnetic rod. The electromagnetic module controls the electromagnetic rod to interfere with the bolt body. The control unit includes a control module, a display module and a magnetic rod detection module for detecting the position of the electromagnetic rod. The control unit receives detection information of the magnetic bolt detection module and controls the display module to display a current state according to the position of the at least one electromagnetic rod.
