The spring is used for automatic resetting, and the connecting wire 11 of the mechanism detecting unit passes through the carrier plate, and the rack 3 is inserted into the electrode shaft 4 through the insertion hole 10 when mounted. The waterproof and insulating shell is protected by Made of water material, it has good insulation, high firmness and strong support.

The bearing is mounted in the sleeve 5 on the carrier plate 6 for stabilizing the electrode shaft 4 and ensuring the smoothness of its rotation. The lock pin is caught in the side groove and the recessed hole of the electrode shaft to prevent the pin from being riveted. As shown in the figure, in the unlocking mechanism, the electromagnet 1 is a monostable electromagnet, and the mechanism state detecting unit is used to detect whether the lock is opened or reset, and the main control unit of the computer key controls the monostable electromagnet.
