A cutting tool clamp mechanism 10 for a power tool includes a housing 30 supported on a spindle 26, the spindle being configured to drive a cutting tool, such as a saw blade 14. A locking member 34, 38, 42 is positioned in and movable with respect to the housing, and includes a slot (118, fig 3) for receiving the cutting tool, the slot defined by at least one surface 122, 126 for engaging the cutting tool. A biasing member 50 is configured for applying a force to the locking member to bias the at least one surface of the locking member into engagement with the cutting tool when received in the slot. The locking member is movable between an engaged condition, in which the slot receives the cutting tool when moved in a first direction 82 into the housing and the at least one surface of the locking member is engageable with the cutting tool to resist withdrawal of the cutting tool, and a released condition, in which the locking member moves against the force of the biasing member and the at least one surface of the locking member is disengageable from the cutting tool in a second, opposite direction 94. Preferably, the clamp mechanism is for a reciprocating saw. |
