Abstract:
1. A detachable hard drive with an electromagnetic switch comprising: a tray for carrying a hard drive; a fastening unit coupling with the tray for conducting interference with a housing body of an electronic product for firmly conjoining the tray and the housing body; and an electromagnetic switch coupling to the fastening unit, and electrically connecting to the hard drive; wherein the electromagnetic switch is powered on when the hard drive is in operation, and then the fastening unit is electrically controlled by the electromagnetic switch so as to automatically fasten a handle of the fastening unit; wherein the fastening unit further comprises: a handle including a first end with a first interference element, and a second end with a second interference element wherein the first interference element is used to conduct interference with an interference element corresponding to the housing body of the electronic product; a housing body having a first end and a second end with the first end of the housing body pivotally connecting to the first end of the handle; a third interference element having a first end and a second end, the first end of the third interference element connecting to the housing body, and the second end extending to the exterior side of the housing body and conducting interference with the second interference element; a fourth interference element connecting to the housing body at one side, and having a stopper at the other side; wherein the electromagnetic switch further has a movable rod; when the electromagnetic switch is powered on, the movable rod forces the stopper to prevent the second end of the third interference element being released from interference with the second interference element.
