The present invention relates to a fixing device for preventing sagging of a fruit tree, and more specifically, by allowing the branches of a fruit tree to be supported so that the branches of the fruit tree can be prevented from being excessively bent and broken by the weight of the fruit, as well as being gathered to one side By preventing sunlight from being blocked by the branches, fruit and fruit trees can be effectively grown, and as the work progresses in a way that the branches of the fruit tree are hooked and fixed, it is possible to quickly install and dismantle. It relates to a fixing device for preventing sagging of an economical fruit tree. The fixing device for preventing sagging of a fruit tree according to a preferred embodiment of the present invention is a spring member that is stretched and stretched linearly, and is located inside the spring member, but is formed with a maximum tensile length of the spring member, and both ends thereof are the spring member Rope member fixed to both ends of the, and one side is formed in a clip shape that is selectively opened and closed, one side of which is selectively hung on the side of the spring member and the other side has a plurality of branches of a tree branch of a fruit tree to move in a predetermined direction A first fixing member is included. The fixing device for preventing sagging of a fruit tree according to another embodiment of the present invention is a spring member that is stretched and stretched linearly, and is located outside the spring member, but is formed with a maximum tensile length of the spring member, and both ends of the spring member A rope member fixed at both ends and a clip shape on which one side is selectively opened and closed, and one side thereof is selectively hung on the side of the spring member, and on the other side, a plurality of agents allowing the branches of the fruit tree branch and the fruit tree to move in a predetermined direction. 1 Fixing member is inclu
