Abstract: The clutch assembly includes a controlling lever, a push bar, a locking shaft, a guiding sleeve, a driving sleeve, and a restoring spring member. The locking shaft has several locking protrusions and several guiding protrusions formed thereon. The push bar is driven by the control lever to push the locking shaft axially move along a rotation axis, and the guiding protrusions therefore engage with the driving sleeve. The driving sleeve is driven to rotate for making the locking protrusions aligned with the locking grooves. The restoring spring member bounds and pushes the locking shaft to an engaging position while the locking protrusions are received in the locking grooves. Thus, the clutch assembly is easily switched from a disengagement status to an engagement status.
