[0042] The working principle of the utility model is as follows: the spring 20 is installed into the spring installation groove 107 of the unlocking knob 10, and the spring action surface 201 is fitted with the spring compression surface 103; the unlocking knob 10 equipped with the spring 20 is installed on the upper cover 60, and the spring support surface 202 is fitted with the spring action surface 605. At this time, under the action of the spring pre-installed force of the spring 20, the locking surface 101 of the unlocking knob is fitted with the locking support surface 601 of the upper cover. The inner sealing hole 501 of the sealing ring 50 is fitted onto the clutch rotating shaft 402, and the clutch sleeve 40 equipped with the sealing ring 50 is inserted into the upper cover mounting hole 606 from the back of the upper cover 60, and splined with the unlocking knob 10. The self-tapping screw 30 is fixedly connected with the unlocking knob 10 and the clutch sleeve 40 through the screw mounting hole 106 and the clutch sleeve screw mounting hole 401. The die-casting head 701 and the pull wire 702 pass through the pull wire fixing hole 603, the sealing baffle 703, the elastic sealing ring 704, and the sleeve head 705 are inserted into the pull wire fixing hole 603, and the screw 80 is fixedly connected to the pull wire assembly fixing hole 604 through the fixed installation hole 7051. The baffle 703 acts in the pull wire fixing hole 603 to limit the displacement of the elastic sealing ring 704 to achieve the sealing function; the external force can pull the pull wire 702 in the pull wire assembly 70. The pull wire 702 installs the die-casting head 701 into the die-casting head installation hole 104 from the installation guide groove 105, and then installs the pull wire 702 into the avoidance guide groove 108 to prevent the die-casting head 701 from falling out when the unlocking knob 10 is turned.

[0043] In case of emergency unlocking, the pull rope tail end 7021 is pulled. The pull rope tail end 7021 can be looped, crimped, or equipped with accessories for easy manual grabbing. The pull rope tail end 7021 moves along the trajectory of the pull rope assembly 70 in the holes of each part, thereby driving the die-casting head 701. The die-casting head 701 applies a pulling force to the die-casting head mounting hole 104, driving the unlocking knob 10 to rotate counterclockwise, thereby causing the clutch sleeve 40 to drive the internal transmission until the locking surface 101 on the unlocking knob is in contact with the locking support surface 601 on the upper cover, completing the emergency unlocking action of the electronic lock.

[0044] During emergency unlocking, the tension drives the unlocking knob 10 to rotate counterclockwise, so that the spring compression surface 103 drives the spring action surface 201 to continuously compress the spring 20, until the unlocking surface 102 of the unlocking knob fits with the unlocking support surface 602 of the upper cover, and the electronic lock is emergency unlocked. After the emergency unlocking is completed, stop pulling the tail end 7021 of the pull rope, and the tension disappears. Under the action of the rebound force of the spring 20, the spring action surface 201 drives the spring compression surface 103 to rotate the unlocking knob 10 clockwise. The unlocking knob 10 drives the clutch sleeve 40. Under the action of the electronic lock clutch mechanism, the clutch sleeve 40 idles and does not drive the electronic lock motion structure. While the unlocking knob 10 drives the clutch sleeve 40, it also drives the die-casting head 701, and the die-casting head 701 drives the pull wire 702, thereby realizing the automatic resetting of the pull rope. The resilience and initial preload of the spring 20 are greater than the friction generated by the clutch sleeve 40 and the various resistances of the pull wire 702 in the pull wire assembly 70. The unlocking knob 10 continues to rotate until the locking surface 101 of the unlocking knob fits with the locking support surface 601 of the upper cover, thereby completing the self-resetting action of the emergency unlocking pull wire.
