AI summary

An electronic lock includes a base, an electromagnetic mechanism, a connecting mechanism, a clamping mechanism and a magnetically-attractable plate. The base has an opening. The electromagnetic mechanism has a protrusion block. The electromagnetic mechanism is installed within the base. The protrusion block is penetrated through the opening and exposed outside the base. The connecting mechanism is connected with a rear cover. The clamping mechanism is arranged between the connecting mechanism and the electromagnetic mechanism. Moreover, the magnetically-attractable plate is connected with the clamping mechanism. When the electromagnetic mechanism is electrically conducted to generate a magnetic attraction force, the magnetically-attractable plate is attracted by the magnetic attraction force, so that the clamping mechanism is attracted on the electromagnetic mechanism. By pushing the protrusion block of the electromagnetic mechanism, the clamping mechanism is correspondingly moved and disengaged from the connecting mechanism.
