ABSTRACT:
An upright post and board holder arrangement includes two clamp blocks threaded onto a double-thread screw rod and moved with a slide block in longitudinal sliding grooves on an upright post. A board holder is fixedly connected to the double-thread screw rod and turned within 180.degree. angle between a upward position where the clamp blocks are moved inwards along the screw rod and clamped on the slide block to fix the slide block in position, and a downward position where the clamp blocks are moved apart from the slide block along the screw rod for permitting the slide block and the clamp blocks to be moved along the longitudinal sliding grooves of the upright post to the desired elevation.
