Patent ID: 8066041

Claim:
A routing machine comprising: a base unit including an inner surface; a motor unit releasably positioned in the base unit, the motor unit including an outer surface engaging the inner surface of the base unit; a clamp mechanism operatively connected to the base unit, the clamp mechanism being moveable between a clamping position and a release position, the clamp mechanism configured to apply a clamping force to the outer surface of the motor unit when the clamping mechanism is in the clamping position and the motor unit is positioned in the base unit; and a moveable clamp adjustment member operatively connected to the clamp mechanism, wherein movement of the clamp adjustment member when the clamp mechanism is in the clamping position adjusts the clamping force applied to the outer surface of the motor unit by the clamp mechanism; wherein the motor unit includes an electric motor and a rotatable drive shaft, the drive shaft including a coupling device configured to receive a router bit; and wherein the clamp mechanism comprises a plurality of clamp members interconnected as a four-bar linkage.
