Abstract
A clamping mechanism for a power tool which has a bayonet washer rotatably mounted on the end of a plunger so that the bayonet washer is rotatable between an open and a closed position. The bayonet washer is biassed towards the closed position by a torsion spring, but is latched in the open position when no operating member is positioned in the clamping mechanism. When an operating member is inserted into the mechanism through a slot in the bayonet washer and into engagement with the plunger, the washer is automatically released from the open position and rotates under the biassing force of the torsion spring to the closed position whereupon the operating member is locked into the power tool.
