According to the present invention, the main purpose is to provide a tool head positioning structure for a flexible wrench, which includes a handle and a tool head pivotally connected to the handle. The handle includes a controller associated with a retaining member disposed between the controller and the tool head, and the retaining member can be controlled to approach or away from the tool head by rotating the controller. The controller has two continued surfaces, which are pushing portion and retracting portion respectively, and each surface has a depth different from each other. The handle further includes a resilient device engaged to the controller so as to keep in a required position. A user can rotate the controller to make the pushing portion or the retracting portion be aligned with the retaining member so as to fix or adjust an angle of the tool head.
