A safety helmet visor setting mechanism includes a shell having a shaft base inside at each side, with one side provided with a shell base provided with an internal lodging space and with an external wall. A control mechanism, located at the right side of the shell, has a knob for turning and driving an actuating element that again links a handle to rotate a displacement. The knob and the actuating element are provided with a fixed dish in between and provided with corresponding oblique chunks and sliders in between. The fixed dish and the handle are provided with corresponding clasp segments and lumps. A joint mechanism, set up on the shaft base of both sides of the shell, includes a first visor joint and a second visor joint each provided with hollows. The first visor joint and the handle of the control mechanism are linked by a rod. A visor has a clasp slice at each of both sides for insertion into the hollow of the visor joint.
