There is disclosed a handheld power tool configured to hold an accessory so as to be operable by a user of the tool to drive the accessory, the power tool comprising: a motor; a housing in which the motor is contained; a spindle assembly which is mounted within the housing and comprises a spindle drivable by the motor; and a clamp assembly arranged at a lower end of the spindle, the clamp assembly comprising opposed first and second clamping members between which a central portion of the spindle assembly extends, said portion being able to be received in an open-ended aperture in the accessory, the first clamping member being moveable, in a direction parallel to the spindle axis, from a first position which is such that the clamp assumes a closed condition whereby, when said central portion is so received, the accessory is clamped by the clamping members so as to be fixedly coupled to the spindle, to a second position which is such that the clamp assumes an open condition permitting the accessory to be moved in a direction transverse to the axis such that the central portion is passed through the open end of the aperture and the accessory is thus removed from the power tool; and an actuator operable by the user to effect the movement of the first clamping member from the first position to the second position. |
