Abstract: A rod rest including a holder frame, a main support having a barrel at the bottom pivoted to the holder frame at one end; two anchoring bars pivoted to the holder frame at an opposite end; an auxiliary support pivotably fastened to the main support by a wing screw; a locating shaft turned in the barrel of the main support and connected between the holder frame and a circular coupling plate; brake means mounted in an axial cut in the locating shaft, and a lever adapted for releasing the brake means; wherein when the main support is turned outwards relative to the anchoring bars, it is released from the constraint of the brake means and allowed to be turned outwards further; when the main support is turned inwards toward the anchoring bars, the brake means is forced into braking position to stop the main support from turning.
