Abstract
The knob lock of the present invention includes a knob, a first driving unit disposed on the knob, a driving barrel, a second driving unit, a lock unit, and a lock core. When the lock core is in a locked state, the driving barrel is restricted from rotating by the lock core, and the knob rotates alone with respect to the driving barrel. When the lock core is in an unlocked state, the restriction to the rotation of the driving barrel by the lock core is removed, the first driving unit applies a driving force on the second driving unit when the knob rotates, and the driving force rotates the driving barrel to make the lock unit rotate together.
