Abstract
A safe electromagnetic lock including a first bolt provided with an elastic fastener, an elastic slide bolt positioned on an end of the first bolt, an electromagnetic device connected to a computer and a second bolt. The computer controls induction of the elastic fastener by the electromagnetic device, and a key inserted into a first keyhole, or another key inserted into a second keyhole, controls sliding movement of the elastic slide block to push against the elastic fastener, thereby releasing an abutting state and effecting unhindered unlocking of the safe electromagnetic lock. Upon unlocking, a front end of the second bolt extends out from a case, and protruding mount of the second bolt is used to press down on a steel ball, thereby enabling the second bolt to achieve a solid fixation and effectively preventing mistakenly locking and avoiding forgetting to lock the safe electromagnetic lock.
