Abstract
A blade replacement apparatus is disclosed, including a nut loosening/tightening member, a locking member, and an operating member, wherein one of the nut loosening/tightening member and the operating member is provided with a first matching portion, and the locking member is provided with a second matching portion. The operating member is movable between an operating position and a non-operating position. When the operating member is in the non-operating position, the first matching portion engages with the second matching portion. The locking member and the operating member are rotatable to one another. Rotation of the nut loosening/tightening member around a first axis is obstructed by the locking member. When the operating member is in the operating position, the first matching portion is disengaged from the second matching portion, and rotation of the nut loosening/tightening member around the first axis tightens or loosens the nut.
