摘要： A power tool having a housing, a motor disposed in the housing, a power cord connected to the motor, and a cord protector operably engaging the power cord for movement therewith. The cord protector comprises a cam follower bracket having a camming slot sized to receive a cam follower. The cam follower bracket being biased into an initial position and exerting a biasing force upon the power cord in response to a load being applied to the power cord.

摘要： A power tool having a housing, an electric motor disposed in the housing, and a spindle drivingly attached to the electric motor. The spindle includes a cavity adapted for receiving a bit therein and a window extending through the spindle in communication with the cavity. The power tool further has a retention device including a bit engaging member disposed within the housing and operable to extend through the window and retain a bit within the cavity. The power tool still further has an actuator operable by a user externally of the housing to disengage the bit engaging member from a bit received in the cavity and, finally, a mechanical interconnection system operably coupled between the actuator and the retention device to actuate the retention device in response to the actuator, wherein the mechanical interconnection is disposed within the housing.
