Abstract
A damping mechanism of a camera tripod head includes a fixing seat, a spindle connected to the fixing seat, damping devices fitted on the spindle, and a rotary seat. Each damping device includes a damping disc, a stop block fitted on the spindle, and a drive device for pushing the stop block to slide along the spindle. The damping disc includes an inner ring and an outer ring. The stop block is movable to disengage from the inner ring of the damping disc by the drive device. The drive device includes a push lever, a seesaw plate hinged to the fixing seat, and a cam mounted on the fixing seat. One end of the push lever leans against the stop block. One end of the seesaw plate leans against another end of the push lever. Another end of the seesaw plate leans against the cam.
