The utility model relates to a tree scissor which can reduce the opening of the grip, which comprises a cutting part, a first grip and a second grip, wherein the cutting part comprises a first blade and a second blade which are mutually pivoted, the first grip connects the first blade, the second grip is provided with a front section and a back section, the front section and the second blade are connected, and the front section and the back section are mutually nested.Another connecting rod is pivoted to the first grip at one end and to the rear section of the second grip at the other end, so that when the two grips are open, the relative displacement between the front section and the rear section of the second grip will be generated by the connecting rod, so as to change the length of the second grip and reduce the opening of the two grips, thus saving the application force during shearing.一種可減少握把開度之樹剪，其包括有一剪切部、一第一握把及一第二握把，其中剪切部包括有相互樞接之一第一刀刃及一第二刀刃，第一握把連接第一刀刃，而第二握把設有一前段及一後段，前段與第二刀刃連接，且前段與後段相互套接。又一連桿以其一端樞接至第一握把，另一端樞接至第二握把之後段，俾於兩握把張開時，藉由此連桿牽動第二握把之前段與後段產生相對位移，藉以變化第二握把之長度而減少兩握把的開度，進而節省剪切時之施力。
