Claim 2:
3. The control method of electronic lock according to claim 2,
wherein the force applying structure is a telescopic body spring or a second permanent magnet;
that the telescopic body is connected to the force applying structure body is that the telescopic body is connected to the telescopic body spring; when the telescopic body is in the retracted state, the telescopic body spring exerts a downward force on the telescopic body, and, the telescopic body is composed of a material that can be absorbed by magnetic force; or that the telescopic body is connected to the force applying structure body is that the telescopic body is mounted with the second permanent magnet, the second permanent magnet repels a magnetism of the first permanent magnet when the telescopic body is in an extended state, and keeps the telescopic body in the extended state; when the telescopic body moves upward to the retracted state, the second permanent magnet generates a magnetic attraction with the first permanent magnet with a displacement relative to the first permanent magnet, so as to maintain the telescopic body in a retracted state.
