The utility model relates to the technical field of photographic machines, in particular to a stable support device for a time-
delay photographic
machine, which comprises a tripod support frame, a guide post and a quick mounting component, according to the device, a second rotary knob is rotated, the second rotary knob drives a second
threaded rod to rotate, fixing of a rotating block is relieved, the rotating block is rotated, the rotating block drives a photographic
machine body to rotate, a rotating rod is pressed, the rotating rod drives a second end-toothed disc to slide, the second end-toothed disc is made to break away from a first end-toothed disc, and limiting of the first end-toothed disc is relieved; a second end-toothed disc extrudes and compresses a first spring, then a connecting block is rotated, the connecting block drives the photographing
machine body to rotate, a first knob is rotated, the first knob drives a first
threaded rod to rotate, the first
threaded rod drives a supporting rod to slide on the inner side of a guide column, the supporting rod drives the photographing machine body to move, and therefore the photographing machine is adjusted; different scene and creative requirements are met, and the quality of the whole time-
delay photography work is improved.
