ABSTRACT:
A safety coupling for quickly disconnecting a cutting instrumentality from the power source of a hand-held power tool comprises a pawl on a rotating driving member engaging an abutment on a coaxial driven member. During normal operation a trip arm holds the pawl engaged. When the trip arm is tripped to release the pawl, a latch prevents reengagement of the pawl until reset.
