Quick release tilt adjustment mechanism

摘要

A support particularly adapted to support an electric fan is provided. The support has a cam action quick release mechanism which is movable between locked and free positions. When the release mechanism is in the free position the fan can be easily rotated to a desired degree of tilt about a horizontal axis. When the release mechanism is in the locked position rotation of the fan is prevented. The support also includes tilt limiting mechanisms which sets a predetermined forward and backward limitation on fan rotation.
