Abstract: A shear, containing a first blade and a second blade, and a first controlling pole and a second controlling pole, while the first and second controlling pole are respectively connected with a spindle to the first blade, the second controlling pole is also spindly connected to the second blade; a gear part is set at the point where the first controlling pole meet the second blade. A much better and efficient level system is applied to our invention, and the gear part in it can disperse the force and resistance when cutting branches bore by the few connections, consequently provide user a chance to save strength while at the same time easy to operate.
