Abstract: The present disclosure relates to a support frame including a first pan-tilt connector and a leg assembly connected thereto and including a primary leg and a secondary leg. A leg adjustment structure is provided between and configured to unlock or lock the primary leg and the secondary leg, so that the primary leg and the secondary leg can move relative to each other or keep relatively stationary; the secondary leg comprises a first sub-leg and a second sub-leg which are configured such that the first sub-leg and the second sub-leg can be unfolded or folded with respect to each other; when the first sub-leg and the second sub-leg are unfolded, the primary leg, the first sub-leg and the second sub-leg are in a three-leg support state. The present disclosure further provides a photographing device, which comprises the support frame and an image acquisition apparatus mounted on the support frame.

Abstract: The present disclosure relates to the technical field of adjustment and installation of photography and video recording, in particular, to a quick-mounting structure, an adaptor ring and a filter. The quick-mounting structure includes a rotating groove body, wherein the rotating groove body is provided with a sliding groove therein, a notch is provided in the side wall of the sliding groove, and the rotating groove body is provided on the first connecting member; and a stopper, wherein the stopper is provided on the second connecting member, and can get into and out of the sliding groove through the notch.

Abstract: A quick connection mechanism includes a truncated-cone-shaped quick release plate, a base, and a locking structure. A tapered clamping groove is provided in a larger bottom surface of the quick release plate. A sliding groove is provided in the base, and the quick release plate is clamped in the sliding groove. The locking structure is configured to fix the quick release plate that enters the sliding groove. The locking structure includes a rotating shaft, a locking arm rotatably provided on the rotating shaft, and a first elastic member connected to the locking arm and configured to apply, to the locking arm, a force in a direction for locking the quick release plate. One end of the locking arm abuts against an inner side wall of the clamping groove and is configured to enable locking of the quick release plate in the sliding groove by the abutment.

Abstract: Disclosed are a rotating assembly, a supporting stand, and a photographing device. The rotating assembly includes a head adjusting structure including a first button, a first toothed disc, a second toothed disc, and a first elastic member. The first toothed disc is fixedly connected with a first head connector. The first elastic member is configured to enable teeth on the second toothed disc to mesh with teeth on the first toothed disc. The first button is configured to overcome an elastic force of the first elastic member under the action of an external force, so that the teeth on the second toothed disc are disengaged from the teeth on the first toothed disc. The angle of the first head connector fixedly connected to the first toothed disc is adjusted by using the first button, the first toothed disc, the second toothed disc, and the first elastic member.
