An electronic padlock comprising:
- an outer casing unit including a case body that includes
- an accommodation space,
- a rear base wall having a rear opening communicated with said accommodation space, and
- a rear cover plate removably mounted to said rear base wall to cover said rear opening, and having a securing groove;
- a security module rotatably mounted to said rear base wall, and having
- a swing member that is disposed swingably in said accommodation space, and that has a rotation restricting portion, and a hook portion removably engageable with said securing groove of said rear cover plate,
- a rotatable button that is disposed outside of said accommodation space, that extends into said accommodation space to connect said swing member, and that is operable to rotate said swing member, and
- two spaced apart insertion holes that extend through an outer surface of said case body and an inner surface of said case body in a top-bottom direction;
- a shackle unit including a long shackle leg and a short shackle leg that are respectively movably inserted through said insertion holes in a top-bottom direction, each of said long and short shackle legs having a notch;
- and
- a clutch unit mounted to said outer casing unit, and including two slide blocks that are movable in a left-right direction, and a blocking member that is movable in the top-bottom direction, each of said slide blocks having an engaging portion for removably engaging a notch of one of said long and short shackle legs;
- wherein said blocking member is movable in said top-bottom direction between a locked position and an unlocked position;
- wherein, in the locked position, said blocking member is interposed between said two slide blocks to lock said slide blocks against movements that causes said engaging portions of said slide blocks to disengage from said notches of said long shackle le and said short shackle leg, so that a bottom end of said long shackle leg stably presses said rotation restricting portion of said swing member, and so that said hook portion of said swing member stably engages said securing groove of said cover plate;
- wherein, in the unlocked position, said blocking member is distal to said slide blocks to allow movements of said slide blocks that causes said slide blocks to disengage from said notches of said long and short shackle legs, so that said bottom end said long shackle leg unpresses said rotation restricting portion of said swing member, said rotatable button is operable to rotate and disengage said hook portion of said swing member from said securing groove of said rear cover plate.
