Specifically, during the unlocking process, when the stop pin 113 of the first lock catch 11 is moved out of the limit groove 203c by the driving pin 1555 of the second lock catch 15, in order to ensure the normal opening of the pot cover 100, the driving pin 1555 is moved along the direction of the second stop block 203b toward the first stop block 203a, so that the first stop block 203a is moved from the limit groove 203c to the position where the first stop block 203a faces away from the outer surface of the outer pot 2033, and when the driving pin 1555 is moved to the position where the second stop block 203b faces away from the outer surface of the outer pot 2033, the surface of the stop pin 113 facing the limit groove 203c has a gap with the outer surface of the first stop block 203a facing away from the outer pot 2033, so that the stop pin 113 is prevented from colliding with the first stop block 203a when moving along the direction of the second stop block 203b toward the first stop block 203a, so as to ensure that the stop pin 203113 can stably move to the position where the first stop block 203a faces away from the outer surface of the outer pot 2033, thereby ensuring the normal opening of the lid 100.

Further, referring to fig. 5 and 8, when the height direction of the pot body 200 is projected to the horizontal plane, the distance between the first stop block 203a and the second stop block 203b in the circumferential direction of the outer pot 2033 is L1, and the length of the second stop block 203b in the circumferential direction of the outer pot 2033 is L2, which satisfies L1 < L2. During unlocking, when the driving pin 1555 slides to the position above the limit groove 203c along the direction of the second stop block 203b toward the first stop block 203a, at this time, the driving pin 1555 is no longer abutted by the surface of the second stop block 203b facing away from the outer pot 2033, in order to prevent the stop pin 113 from falling into the limit groove 203c, at this time, the stop pin 113 is abutted by the surface of the first stop block 203a facing away from the outer wall of the pot body 200, that is, when the driving pin 1555 moves to the limit groove 203c, the stop pin 113 synchronously moves to the surface of the first stop block 203a facing away from the outer pot 2033, so that the distance value L1 between the first stop block 203a and the second stop block 203b in the circumferential direction of the outer pot 2033 is greater than the length value L2 of the second stop block 203b in the circumferential direction of the outer pot 2033, so as to ensure the normal unlocking process of the lock body structure 10.

Further, the length of the first stopper 203a in the circumferential direction of the outer pot 2033 is L3, which satisfies L3 > L1. During unlocking, when the stop pin 113 slides out from the surface of the first stop block 203a facing away from the outer pot 2033 to the outer surface of the outer pot 2033, in order to avoid that the drive pin 1555 falls into the limit groove 203c to hinder unlocking, the length value L3 of the first stop block 203a in the circumferential direction of the outer pot 2033 is greater than the distance value L1 of the first stop block 203a and the second stop block 203b in the circumferential direction of the outer pot 2033, and when the stop pin 113 slides out from the surface of the first stop block 203a facing away from the outer pot 2033 to the outer surface of the outer pot 2033, the drive pin 1555 has already slid to the point that the first stop block 203a faces away from the outer surface of the outer pot 2033 and is abutted by the outer surface of the outer pot 2033, so that the drive pin 1555 is prevented from falling into the limit groove 203c, thereby ensuring a normal unlocking process of the lock body structure 10.
