The present invention is designed to provide a cutting wire (10) connection structure for a brush cutter which is safer and more convenient and is capable of reducing a manufacturing cost by combining a synthetic resin cutting wire (10) instead of a metallic cutting blade with a cutting head (1) of a brush cutter. In the present invention, in a cutting head (1) which is spin-connected by a rotation axis of a brush cutter and consists of a body (2), a wrap reel (3) and a combination cover (4), a wire inlet hole (32) is formed on both sides of a wrap in which a wrap groove (31) is formed up and down. A coupling hole (33) that penetrates a wrap reel (3) in a semicircle is formed inside the up-and-down wrap groove (31) through a wire inlet hole (32) in both sides, and thus a cutting wire (10) flows in a wire inlet hole (32) before being twined by a wrap groove (31). After the middle part of the cutting wire (10) is located in a coupling hole (33), the wrap reel (3) is rotated in the main body (2), a cutting wire (10) is twined in the up-and-down wrap groove (31). According to this, the bent synthetic resin cutting wire (10) is used instead of a metallic cutting blade in case of facing an obstacle. Thus, the safety is greatly improved by preventing a safety accident such as fragments or pebbles at the time of cutting brushes. The manufacturing cost is reduced and the convenience of uses is improved, and the cutting efficiency and durability are improved. Thus, product compliance becomes redouble. As such, many effects can be anticipated.COPYRIGHT KIPO 2016본 발명에서는 예초기의 절단헤드(1)에 금속제 절단블레이드 대신 합성수지제 절단와이어(10)를 결합하여 보다 안전하고 편리하며 제조원가를 절감할 수 있는 예초기용 절단와이어(10) 연결구조를 제공코자 하는 것이며, 상기 본 발명은 예초기의 회전축에 회전 연결되며 본체(2)와 권취릴(3) 및 결합커버(4)로 이루어진 절단헤드(1)에서, 상하로 권취홈(31)이 형성된 권취릴(3)의 양측에 각각 와이어유입공(32)이 형성되며, 양측 와이어유입공(32)을 통해서 상하 권취홈(31) 내측에 권취릴(3)을 반원형으로 관통되는 결합공(33)이 형성되어 절단와이어(10)가 권취홈(31)에 감기기 전에 와이어유입공(32)으로 유입되어 절단와이어(10)의 중간이 결합공(33)에 위치되도록 한 후 권취릴(3)을 본체(2)에서 회전시켜서 상하의 권취홈(31)에 절단와이
