The invention relates to the technical field of mechanical design, in particular to a shape design method of a special wrench for a complex space, which comprises the following steps of: establishing a complex space model, and marking a tightening point position and an operation area; abstracting the complex space model, and establishing a discrete space map; processing the discrete space map, and marking a passable area and an impassable area; constructing an evaluation function, and converting constraint conditions of wrench design into weights; selecting an optimal path of the evaluation function by using a path-finding algorithm; and smoothing an path curve, and verifying whether interference exists in the space. By means of the design method, the contour central axis of a special-shaped wrench is designed and optimized, and the problem that the design efficiency of a wrench for complex space is low can be effectively solved. 本发明涉及机械设计技术领域，特别是涉及一种复杂空间专用扳手的形状设计方法，包括以下步骤：建立复杂空间模型，标示拧紧点位和操作区域；将复杂空间模型抽象化，建立离散
