Abstract: A padlock includes a housing, a shackle having a pivoting portion pivotally passing through a first top hole of the housing into an accommodation chamber of the housing and a locking end passing through a second top hole of the housing, a retaining device disposed in the accommodation chamber and having at least two driving wheels for controlling an axial movement of the pivoting portion of the shackle, and at least two pointers located above a dial of the housing and respectively driven by the driving wheels to point to one of figures of the dial. When both of the pointers point to correct figures, the pivoting portion of the shackle is axially moveable relative to the housing under the control of the driving wheels, such that locking end of the shackle is moveable away from the second top hole of the housing to unlock the padlock.

Abstract: A padlock includes a base, a combination controlled lock unit having a shaft passing through a top hole of the base into an accommodation chamber of the base, three combination wheels rotatably sleeved onto the shaft, and three retaining wheels sleeved onto the shaft and respectively engaged with the combination wheels, a driving member connected with the shaft, two shackles having bottom ends respectively connected to the base and top ends detachably engaged with each other, and a latch connected with the shaft so as to be driven to move between a locking position where a block portion of the latch stops at least pivotable one of the shackles from movement for ensuring engagement of the top ends of the shackles and a unlocking position where the block portion moves away from the pivotable shackle for allowing disengagement of the top ends of the shackles.
