One side of the front end of the adjusting plate 8 is fixedly connected with a resisting frame 5. The upper and lower ends of one side of the resisting frame 5 are respectively movably connected with movable shafts 10;
[0029] The shape and size of the outside of the adjusting plate 8 are adapted to the shape and size of the inside of the limit sleeve 6. The adjusting plate 8 can slide left and right along the inside of the limit sleeve 6. One end of the hand-tightening bolt 7 passes through the limit sleeve 6 and extends into the positioning screw hole 9. The position and size of the hand-tightening bolt 7 and the positioning screw hole 9 correspond one by one. The positioning screw holes 9 are arranged at equal intervals. The vertical centerlines of the push head 4 and the resisting frame 5 coincide. The movable shafts 10 are symmetrically distributed about the horizontal centerline of the resisting frame 5, and the straightening operation range can be adjusted to adapt to steel bars with different bending amplitudes;
[0030] Specifically, as shown in Figure 1 , Figure 2 and Figure 3 , loosen the four hand-tightening bolts 7 one by one. The hand-tightening bolts 7 are disengaged from the positioning screw holes 9. At this time, the adjusting plate 8 can be slid left and right along the inside of the limit sleeve 6. After adjusting to the appropriate position, tighten the hand-tightening bolts 7 again. The hand-tightening bolts 7 are inserted into the positioning screw holes 9, and the position of the adjusting plate 8 can be limited. The position of the resisting frame 5 is also limited, and the distance between the push head 4 and the resisting frame 5 can be adjusted.

The upper and lower groups of switch buttons 20 respectively correspond to extension and retraction. Press the switch button 20 to make the electric cylinder 2 extend outwards, and the push head 4 approaches the abutment frame 5 to squeeze and straighten the bent part. According to the bending degree of the steel bar, the distance between the push head 4 and the abutment frame 5 can be adjusted. First, loosen the four groups of hand-tightening bolts 7 one by one, and the hand-tightening bolts 7 are disengaged from the positioning screw holes 9. At this time, the adjusting plate 8 can be slid left and right along the inside of the limit sleeve 6. After adjusting to the appropriate position, tighten the hand-tightening bolts 7 again. The hand-tightening bolts 7 are inserted into the positioning screw holes 9, and the position of the adjusting plate 8 can be limited, and the position of the abutment frame 5 is also limited, so that the distance between the push head 4 and the abutment frame 5 can be adjusted. The multiple groups of positioning screw holes 9 can provide multiple adjustment options. When dealing with steel bars with a large bending degree, it can be first opened, first adjust the position of the abutment frame 5, pull it outwards, then press the switch button 20 to synchronously extend the push head 4, so that the first limit rod 11 and the second limit rod 13 can be inserted into the inner side of the steel bar bend, and the first steel bar clamping groove 12 and the second steel bar clamping groove 14 are buckled on the side of the steel bar to prevent the steel bar from sliding. Then press another switch button 20 to retract the electric cylinder 2, and the bent steel bar can be opened to expand its angle for subsequent straightening. When it is idle in daily use, wind the power cord 18 along the outside of the main body 1 of the machine. The fixing seat 15 and the wire harness clamping plate 16 can hold the power cord 18 to prevent it from being scattered, and the wire harness baffle 17 further limits the position of the wire harness.
