Publication number: 20210161076Abstract: 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.Type: ApplicationFiled: November 24, 2020Publication date: June 3, 2021Inventors: An Wei Wei, Li Da Zheng, Frankie Lam Kwok Fan
