An electronically-driven lock (1) includes an inner lock unit (2), an outer lock unit (5), a bolt assembly (3) having a latch, and a transmission shaft (4) extending through the bolt assembly to actuate the latch. The inner lock unit includes a base (80), a driving unit (60), a clutch (50), a knob (30), and a top cover (20) covering the base. The driving unit includes a gear plate (64). The gear plate includes a pair of driving protrusions (641). The knob has a mating shaft (32) fittingly receiving the transmission shaft therein. The clutch includes a pair of driven protrusions (541), and defines a generally rectangular mating slot (52) fittingly receiving the mating shaft therethrough. The driving protrusions engage the driven protrusions to rotate the clutch. The clutch accordingly rotates the mating shaft of the knob to rotate the transmission shaft. Thus the latch can be actuated to locked position or unlocked.
