The invention relates to the technical field of 
steel bar benders, in particular to a portable hydraulic 
steel bar bender. The portable hydraulic 
steel bar bender comprises a 
hydraulic cylinder, a hydraulic shaft, supporting plates and a lifting 
handle, wherein the hydraulic shaft is arranged in the 
hydraulic cylinder, one end of the hydraulic shaft protrudes out of the 
hydraulic cylinder, the twosymmetrically-distributed supporting plates are fixedly connected to the hydraulic cylinder, one sides of the supporting plates are fixedly connected with the n-shaped bent-rod-shaped lifting 
handle,one ends of the supporting plates are fixedly connected with sleeves, the sleeves are movably sleeved with inner shafts, one end of the hydraulic shaft is provided with an outer 
barrel, an inner column is connected between the hydraulic shaft and the outer 
barrel, and one end of the inner column is fixedly connected with the hydraulic shaft. According to the structural design, quick replacement work of connecting pieces of different types and sizes is achieved, air flow in the inner column can be caused to flow only by pressing the 
handle, then a clamping block is controlled, the connecting state between the outer 
barrel and the inner column is controlled, the function is stable and powerful, and the whole bending 
machine can meet the 
machining requirements of reinforcing steel bars of different types.
