Abstract: Disclosed is a blade replacement apparatus of an electric instrument, which is used to replace blades connected by a bolt, the bolt extending along a first axis, the blade replacement apparatus comprising a nut that fits the bolt to fix the blade, a nut loosening/tightening member, a locking member, and an operating member, one of the nut loosening/tightening member and the operating member having a first matching portion, the locking member having a second matching portion, wherein the operating member is movable between an operating position and a non-operating position, the operating member allowing a user to perform an operation by hand without using any instruments; when the operating member is in the non-operating position, the first matching portion engages with the second matching portion, and the rotation of the nut loosening/tightening member around the 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 the rotation of the nut loosening/tightening member around the first axis tightens or loosens the nut.

Abstract: The present invention provides an electric pruner saw, comprising a motor (12), a wobble bearing (13) and a saw (14, 15), and further comprising a balancing component; the balancing component and saw vibrate at the same frequency in parallel directions, but the phases of vibration of the balancing component and saw differ by 180°, such that the opposite-phase vibration of the balancing component partially or completely offsets the vibration of the saw. Furthermore, the wobble bearing in the pruner saw is arranged at an upper side of the motor, such that a rotating rod of the pruner saw is located between the motor and a saw rod; thus, the wobble bearing is closer to the saw rod, so the length of a swing rod of the wobble bearing is shortened, and consequently the various components are arranged more compactly, thus reducing the volume of the pruner saw.
