Multifunctional padlock having shackle limit knob

Abstract

A padlock includes a housing, a shackle, a limit knob, a movable member and a locking mechanism. The shackle is movably mounted on the housing and includes a root section disposed within the housing and a free section which extends from the root section and is disposed outside of the housing. The limit knob is movably mounted on the housing to control movement of the free section of the shackle. The movable member is movably disposed at the limit knob. In addition, the locking mechanism includes a key lock unit disposed in the housing and a movable unit movably disposed in the housing. The key lock unit is configured to control movement of the limit knob and defines a key hole to receive a key. The movable unit includes a first portion engaged with the movable member and a second portion received in and aligned with the key hole of the key lock unit so that when the key is inserted into the key hole to actuate the movable unit, the movable member is driven by the movable unit to move from its original position to an indicative position which is at the limit knob.
