In this way, the driving lever 430 applies force to the rotation stop pin 420 during rotation, which is beneficial to torque transmission. In fig. 5, the stop pin 420 is in the limit position, at this time, the end of the stop pin 420 is locked in the first yielding groove 230 to limit the rotation of the locking pin 200, and in fig. 6, the stop pin 420 is driven by the driving rod 430 to reach the yielding position, at this time, the end of the stop pin 420 exits the first yielding groove 230, and the locking pin 200 can rotate.

In this way, the stopper rod 450 can limit the movement of the driving rod 430 in the axial direction thereof, so that the driving rod 430 can only rotate in the second mounting hole 412, thereby improving the stability of the operation of the emergency unlocking mechanism 400.
As shown in fig. 6 and 8, the emergency unlocking mechanism 400 further includes an anti-pulling pin 460, wherein the anti-pulling pin 460 is disposed in the second mounting hole 412 and is located at a side of the driving rod 430 away from the driving end, a first end of the anti-pulling pin 460 is connected with an inner wall surface of the second mounting hole 412, and the anti-pulling pin 460 extends into the second mounting hole 412. The anti-pulling pin 460 can be matched with and away from the unlocking key, the anti-pulling pin 460 can avoid the rotary motion of unlocking the unlocking key, and the hooking force can be provided for the unlocking key after rotation, so that the unlocking key is prevented from falling off.

In this way, the situation that the operator rotates the locking pin 200 excessively to unlock the lock suddenly and cannot be achieved smoothly is effectively avoided, that is, the second yielding groove 240 effectively plans the movement path of the locking pin 200.
Specifically, as shown in fig. 3, the second yielding groove 240 includes a locking groove section 241, a transition groove section 242 and an emergency unlocking avoidance groove section 243 that are sequentially communicated, wherein the locking groove section 241 extends along an axial direction of the stop pin 420, the transition groove section 242 extends along a radial direction of the stop pin 420, and a length of the transition groove section 242 is equal to a chord length when the stop pin 420 rotates by a preset angle, and the emergency unlocking avoidance groove section 243 is arranged in parallel with the locking groove section 241.
