ABSTRACT:
A safety helmet visor setting mechanism includes a shell having an indent at each side and a long opening behind the indent at one side. An anchored unit fits in the long opening and has two grooves. A hold plate has two push chunks placed in the two grooves respectively. A link bar, fixed in the anchored unit and jostled with the hold plate, can be moved by the drive of the push chunk. A cover, capping the anchored unit, jostles with the link bar and the hold plate for a lockup. A first visor joint, positioned inside the shell in one side, has a bottom end pinned joined with the top end of the link bar, and has a top end provided with a cave. A second visor joint, positioned inside the shell in the other side has a springy slice forming an accommodation space with the shell. A visor has a clasp slice at each side penetrating the caves and the accommodation spaces of both the first visor joint and the second visor joint for assembly.
