The invention provides a non-fault-tolerant principle, and relates to a design method of an anti-pulling spring and a key corresponding to the anti-pulling spring according to the non-fault-tolerant principle. The non-fault-tolerant principle means that faults cannot be tolerated, no effect is achieved as long as no fault is caused, and opposite effects are achieved immediately once a fault is caused. The anti-pulling spring has the non-fault-tolerant characteristic, when a correct key is inserted into the anti-pulling spring in place, the anti-pulling spring has no effect, and when no correct key is inserted into the anti-pulling spring or the correct key is not inserted into the anti-pulling spring in place, a lock cylinder can be clamped by the anti-pulling spring and cannot rotate. The anti-pulling spring is popularized to be used, few improvements can be carried out on current spring locks in all types without increasing any equipment and cost, and anti-theft safety of the spring lock can be greatly improved.
