ABSTRACT:
An improved padlock comprises a lock body and a shackle. The lock body is provided with a tubular bushing containing a rotating rod capable of being actuated by a lock core. The shackle comprises two insertion ends having retaining grooves. As shackle is inserted into the lock body, the retaining grooves engage securely the rotating rod of the lock body to complete the locking process. The unlocking process is accomplished by actuating the rotating rod to disengage the retaining grooves of the shackle.
