Foldable locking mechanism

A foldable locking mechanism comprising:

• a first mounting seat;
• a second mounting seat pivotally connected to the first mounting seat;
• a third mounting seat pivotally connected to the second mounting seat;
• a first locking component at least partially and movably disposed between the second mounting seat and the third mounting seat, the first locking component being movable between a first releasing position and a first locking position, a relative pivotal movement of the second mounting seat and the third mounting seat being allowed when the first locking component is located at the first releasing position, the relative pivotal movement of the second mounting seat and the third mounting seat being restrained when the first locking component is located at the first locking position;
• a driving component disposed on the first mounting seat and abutting against the first locking component, the driving component being configured to drive the first locking component to move from the first locking position to the first releasing position for allowing a folding operation of the foldable locking mechanism;
• and
• a limiting assembly for limiting a relative pivotal angle of the first mounting seat and the second mounting seat;
• the limiting assembly comprises a limiting component installed on the second mounting seat and protruding toward the first mounting seat.
