Referring to fig. 1, 2 and 4, the utility model provides a steel bar bending tool, which comprises a fixed disc 1, a rotating shaft 5, a first upright post 4, a second upright post 6 and a handle 3; the fixed disc 1 is provided with an arc-shaped chute 2; the rotating shaft 5 is arranged at the circle center of the arc-shaped sliding chute 2, penetrates through the fixed disk 1 and can rotate relative to the fixed disk 1; the first upright post 4 and the rotating shaft 5 are arranged outside the arc-shaped sliding groove 2 at intervals, and one end adjacent to the arc-shaped sliding groove 2 is arranged on the disc surface of the fixed disc 1; the handle 3 is arranged at the bottom of the fixed disc 1, one end of the handle 3 is connected with the rotating shaft 5, and the other end of the handle is a free end; second stand 6 slidable is located in arc spout 2 to be connected on handle 3, handle 3 when rotating along with axis of rotation 5, drives second stand 6 at the internal rotation of arc spout 2. The fixed disc 1 is a circular disc or a square disc. It should be understood that, the reinforcing steel bars 7 are placed on the disk surface of the fixed disk 1 to be bent, the initial position of the reinforcing steel bars 7 and the position of bending by 180 degrees are shown in fig. 1 and 4, when the handle 3 drives the second upright post 6 to rotate anticlockwise along the arc-shaped sliding groove, the second upright post 6 drives one end of the reinforcing steel bars 7 to do bending motion, and the first upright post 4 blocks the other end of the reinforcing steel bars 7 to do motion, so that the reinforcing steel bars 7 are bent. Wherein, axis of rotation 5 sets up the position at the semicircle centre of a circle of arc spout 2, and second stand 6 uses axis of rotation 5 as the axle center to do circular motion along arc spout 2 when handle 3 rotates.

Referring to fig. 2, the first upright 4 includes an upright 41 and a bearing housing 42, and the bearing housing 42 is disposed on the upright 41 and can rotate relative to the upright 41. It should be understood that when the reinforcing bars 7 are bent, and the first upright post 4 blocks the movement of the reinforcing bars 7, the reinforcing bars 7 generate friction force on the first upright post 4, and the rotation of the bearing sleeve 42 relative to the upright rod 41 reduces the friction force, thereby reducing the abrasion degree of the reinforcing bars 7 on the first upright post 4.

With continued reference to fig. 2, the stationary platen 1 is further provided with a sleeve 12 penetrating the stationary platen 1, and the rotating shaft 5 is mounted in the sleeve.
