Abstract
A tool-less blade clamps ( ) may include a rod ( ) having a slot ( ) and a guide slot ( ) formed substantially perpendicularly to the slot ( ). A control member ( ) may be slidably disposed within the slot ( ) and a spring ( ) preferably biases the control member ( ) towards a forward portion of the slot ( ). The rod ( ) rotatably supports a sleeve ( ). Preferably, the sleeve ( ) being prevented from axially displacing with respect to the rod ( ) when the sleeve ( ) rotates about the rod ( ). An L-shaped slot ( ) may be formed in the sleeve ( ) and may have a blade lock slot ( ) disposed substantially perpendicularly to a blade lock control slot ( ). The control member ( ) may include a pin ( ) that extends through the guide slot ( ) and travels within the L-shaped slot ( ). The rod ( ) may include a hole ( ) formed substantially perpendicular to the slot ( ). A pressing member ( ) may be slidably disposed within the hole ( ). A cam surface ( ) is preferably defined along an inner surface of the sleeve ( ) and the cam surface ( ) urges the pressing member ( ) towards the slot ( ) when the sleeve ( ) is rotated about the rod ( ) to a blade clamp position. Preferably, rotation of the sleeve ( ) towards a blade release position causes the control member ( ) to move towards the forward portion of the slot ( ) due to the biasing force of the spring ( ) and the sleeve ( ) is automatically locked in the blade release position. Further, insertion of a blade ( ) into the slot ( ) releases the sleeve ( ) from the blade release position and the sleeve ( ) automatically returns to the blade clamping position to securely attach the blade ( ) to the rod ( ).
