ABSTRACT:
A continuously angle-adjustable multifunction tripod is provided. The continuously angle-adjustable multifunction tripod includes a connecting base, at least three legs, an adjusting cap, and a supporter. The adjusting cap and the supporter are disposed on and under the connecting base, respectively. Each of the legs is peripherally distributed around the supporter. Upper ends of the legs are movably connected to the connecting base. Distances between the adjusting cap, the connecting base and the supporter are adjustable along a vertical direction, and can be relatively fixed at anywhere therebetween. Meanwhile, a bottom of the adjusting cap and the supporter clamp and fix the legs, so that an angle of each of the legs relative to the horizontal plane can be arbitrarily adjusted in a range from 0° to 90° in accordance with variations of relative positions of the adjusting cap, the connecting base, and the supporter. The present invention has a simple and compact structure, small volume, light weight, low cost, and convenient to operate. Spans of the legs may be arbitrarily adjusted in a range from 0° to 180°, so that the tripod may be mounted quick and steadily in all kinds of complex environments. The present invention may be widely applied in areas of observation, photography, and illuminating, etc.
