Abstract: The invention discloses a pair of high-torsion electric pruning shears, which include an enclosure (1), wherein a direct current brushless motor 9 is fixedly mounted in the enclosure (1); a socket (8) is connected to a rear end of the direct current brushless motor (9); a front end of the direct current brushless motor (9) is connected with a ball screw (7) through a gearbox (10); a trigger (2) is fixedly mounted on a lower surface of the enclosure (1); a sensing unit is also arranged in the enclosure (1) over the trigger (2); and a shear part driven by the ball screw (7) is mounted at the front end of the enclosure (1). The high-torsion electric pruning shears have the beneficial effects of simple structure and high practicability.
