    摘要： A bit retention device includes a shaft having a sidewall defining a hexagonal cavity extending from a first end thereof and a ball groove extending through the sidewall and communicating with the hexagonal cavity. A ball is disposed in the ball groove and a ball spring engages the ball and biases the ball toward the first end. An actuator sleeve surrounding the shaft includes an internal ramp engaging the ball. A spring biased plunger assembly is disposed in the bore for biasing a bit received in the bore in a direction toward the insertion end.

    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.

    摘要： A power tool with a motor, a transmission and a rotary impact mechanism. The transmission receives rotary power from the motor and includes a transmission output member. The rotary impact mechanism has a first spindle, a second spindle, a hammer and an anvil. The second spindle is disposed coaxially with the first spindle and the hammer is drivingly coupled to the second spindle. The power tool also includes a device that selectively couples the first and second spindles with the anvil and the transmission output member. Coupling of the first spindle with the anvil and the transmission output member directly drives the anvil, whereas coupling of the second spindle with the anvil and the transmission output member drives the anvil through the hammer.

    摘要： A power driver may include a motor that rotates upon receiving an input current. A tool chuck may have chuck jaws to hold an accessory. The tool chuck may be coupled to the motor. A power take off mechanism may be connected between the motor and the tool chuck. The power take off mechanism may be adjustable into a CHUCK MODE to one of open and close the chuck jaws while the motor rotates. An electronic clutch may interrupt the input current to the motor if the power take off mechanism is in the CHUCK MODE and if the input current exceeds a trip value.
