In one embodiment of the present utility model, 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.
