  • Lock device for power tool adjustment
    Patent number: 10556311
    Abstract: A base assembly for a power tool, such as a router, includes a base member, an adjustment mechanism, and a lock member. The base member is configured to accept a motor housing of the power tool. The adjustment mechanism is configured to adjust a position of the motor housing relative to the base member via rotation of a first contact portion of the adjustment mechanism. The lock member is moveable relative to the adjustment mechanism between a first position that prevents rotation of the adjustment mechanism and a second position that permits rotation of the adjustment mechanism. The lock member includes a second contact portion positioned proximate to the first contact portion and configured to be actuated to position the lock member in the second position. The position of the motor housing is adjusted by simultaneously actuating the first contact portion and the second contact portion.
