The utility model relates to a structure of a road tree fixer.It is composed of two clips with the same semicircle shape.At both ends of the clip and extending one wing end respectively,The wing end is provided with a perforating hole in a consistent shape.There are several convex parts on the surface of the semicircle shape.The convex part itself has a through space.An inner convex part is arranged between each two outer convex parts.In order to make the through space of the external convex part wear the steel cable,After that, two pieces can be wrapped around the tree trunk.Then, two bolts and nuts are used to thread through the holes at the two wing ends of the clip.The inner convex part of the clip is close to the surface of the trunk.Two clips are then formed and fixed on the surface of the trunk.After that, the steel nails assembled at the front end of the steel cable are inserted into the ground.In this way,It is fixed under the trees by two clips and several steel cables.In order to support the positioning of trees and provide deep root growth.一種路樹固定器之構造，係由兩呈相同半圓造型的夾片構成，在夾片兩端並分別延伸一翼端，在翼端設有一貫穿狀的穿孔，在半圓造型的表面具有數外凸部，外凸部本身並有一呈透空的貫穿空間，另在每兩外凸部之間則設有一內凸部；俾使在外凸部的貫穿空間得以穿套著鋼索，之後將兩夾片得以包夾著樹木的樹幹，再由兩螺栓暨螺帽來穿置於夾片兩翼端之穿孔螺緊，以為夾片中的內凸部乃貼觸樹幹表面，是兩夾片遂形成固定在樹幹表面上，之後再由鋼索前端所組合的鋼釘做往地面深入插置，如此一來，藉由兩夾片及數鋼索的固定著樹木下，以達到扶住樹木定位及供呈深根成長目的。
