ABSTRACT:
A constriction assembly that has a regulator on two ends of head bands and includes a casing seat, the regulator and a pad. By pressing protruding buttons of the regulator support arms formed on both sides of the buttons are displaced and driving turning bodies to disengage the chuck groves from the projection pieces of the band so that the band can reach a loosened state. In contrary, the band can be constricted by pulling the ends of the band while the protruding buttons are free of pressure.
