Abstract
An inner-lock foldable joint has two base plates. One side of each base plate is articulated with the other base plate by way of a hinge. When a user rotates a lever to lock the two base plates, a braking mechanism drives a latching block to move forward, and two flanges of the latching block are inserted into a groove within a depression on one or both of the base plates.
