Abstract: A padlock has a shell, a lock cylinder, a shackle and a resilient element. The lock cylinder is mounted in the shell and has a lock rod. The shackle is mounted slidably through a front opening of the shell and has a distal end, a proximal end and a protruding segment. The distal end is selectively received in a mounting slot of the shell. The protruding segment selectively abuts the lock rod to keep the shackle from sliding. The resilient element is mounted in the shell and presses against the proximal end of the shackle. With the resilient element, the distal end of the shackle is maintained in the mounting slot without any external force. Therefore, the padlock may still hold an object in position without locking and then the user may take the object easily without using a key.
