The invention discloses a stomatology department occlusion-direction photographing reflector fixator with an angle fine adjusting function. The fixator comprises a base. A groove is formed in the base,a rotary disc is arranged in the groove,a worm wheel is arranged below the rotary disc,a worm is arranged on one side of the worm wheel,a first control rod is fixedly arranged at one end of the worm,the end,away from the worm,of the first control rod penetrates through the base,a first rotary knob is fixedly arranged at the end,located outside the base,of the first control rod,a connecting columnis arranged on the rotary disc,and the two sides of the connecting post are each provided with two extension rods. The fixator has the advantages that the angle of the vertical direction of a reflector can be adjusted,the angle can be adjusted in multiple directions,the reflector can reflect light to portions needing shooting to the maximum degree,thus,the shooting definition of some tiny detailscan be improved,the judgment precision of relevant staff on cases is improved,and labor investment is reduced.
