Claim 3:
4. An electronic lock based on the control method of electronic lock according to claim 3, wherein the electronic lock comprising a lock body composed of a lock body base and a handle, an unlock tool, an electromagnet and a first permanent magnet installed in the lock body base; the unlock tool comprising an unlock mechanism composed of a key, or a lock cylinder, or a knob, or a button, and a corresponding mechanical structure composed of a push rod;
the electromagnet comprising an electromagnetic coil, a telescopic body, and a force applying structure; the telescopic body being placed in a telescopic body movable hole of the electromagnetic coil; the handle having a snap hole, the snap hole being an integral through hole, or being divided into an upper snap hole matched with the telescopic body and a lower snap hole matched with the push rod;
when the electronic lock is closed on the lock body base, the unlock action is performed by the unlock tool, the movement of the unlock mechanism driving the push rod to move up or down, and the handle being coupled by the push rod, so that the handle cannot be opened; the electromagnet, the unlock mechanism, and the push rod that moves under a control of the unlock mechanism being installed in the lock body base; the push rod being controlled by the unlock mechanism to be able to move in a telescopic direction of the telescopic body; when the push rod moves relatively close in the telescopic direction of the telescopic body, the telescopic body in an extended state being pushed to the retracted state; when the telescopic body in the extended state or the push rod in the extended state is located in the snap hole of a corresponding position on the handle, the handle being in a closed state;
when the telescopic body and the push rod in the retracted state are both completely separate from the snap hole, the handle being in the open state;
the first permanent magnet being installed in the lock body base or in the electromagnet for keeping the telescopic body in retracted state when the telescopic body is retracted; the force applying structure applying force to the telescopic body and maintaining the telescopic body in extended state when the telescopic body is extended.
