In some embodiments of the present invention, a locking accommodating cavity and a limiting hole 15 communicating with the locking accommodating cavity are formed in the locking member 12, and at least part of the limiting portion 13 is accommodated in the locking accommodating cavity and protrudes from an outer surface of the locking member 12 through the limiting hole 15 when the unlocked state is switched to the locked state. At least a portion of the driving member 14 is accommodated in the locking accommodating cavity and is connected with the inner wall of the locking accommodating cavity, so that the driving member 14 can move together with the locking member 12 when moving. In one embodiment of the present invention, when the locking mechanism 1 is locked in cooperation with its corresponding locking device, the stopper 13 receives an axial force applied by the locking device at the time of locking. Specifically, when the locking mechanism 1 is switched from the unlocking state to the locking state, the locking member 12 moves towards the direction close to the locking shell 11 under the driving of the driving member 14, the limiting portion 13 moves along with the locking member 12 in the same direction, when the limiting portion 13 contacts with the driving member 14, the limiting portion 13 is acted by the force of the driving member 14, part of the limiting portion 13 protrudes out of the outer surface of the locking member 12 through the limiting hole 15, and the other part of the limiting portion 13 is accommodated in the locking accommodating cavity, so that the locking mechanism can be locked by the supporting force exerted by the locking member 12 when the locking mechanism is locked, wherein the supporting force is opposite to the axial force between the locking device and the limiting portion 13, and the two forces act on the limiting portion 13 together, so that the limiting portion 13 is fixed, and the locking is successful at the moment.
