The invention provides a novel adjustable wall body back ridge. The novel adjustable wall body back ridge comprises transverse levers, telescopic levers and connecting pieces; wherein the telescopic levers are the same as the transverse levers in shapes; the section sizes of the telescopic levers are smaller than those of the transverse levers; the telescopic levers are inserted into the transverse levers and are fixed through the connecting pieces; the connecting pieces comprise rotary adjusting fixing parts, and upper rotary bolts and lower rotary bolts which are fixed at the two ends of the rotary adjusting fixing parts. The novel adjustable wall body back ridge is simple in structure, is reasonable in design, and is convenient to use and operate.
