Ptz assembly and a clamping mechanism thereof

Abstract

The present disclosure provides a clamping mechanism having a base, a first holding mechanism, and a second holding mechanism. The first holding mechanism extends from one side of the base and is movable to form an unfolded position and a folded position relative to the base. The second holding mechanism extends from another side of the base and is movable to form the unfolded position and the folded position. The first holding mechanism restricts movement of an electronic device clamped on the clamping mechanism in a first direction in the unfolded position, the second holding mechanism restricts movement of the electronic device in a second direction in the unfolded position, and the second direction is different from the first direction. In the folded position, the first holding mechanism abuts against the second holding mechanism.
