[0027] Furthermore, by bringing one side of the steel bar into contact with the rear end of the first limiting plate 8 and rotating the adjusting screw 10 , the second limiting plate 12 can be pushed closer to the first limiting plate 8 , thereby clamping and fixing the steel bar.

[0028] Furthermore, after the first limiting plate 8 and the second limiting plate 12 fix one end of the steel bar, the motor 5 drives the turntable 4 to rotate, so that the rotating seat 7 can drive the steel bar to rotate, thereby bending the steel bar with high bending efficiency.

[0029] Reference Figure 1 and Figure 5 As shown, a positioning groove 16 is provided at the upper end of the fixed table 2, and an adjusting block 18 is slidably connected inside the positioning groove 16. A contact plate 19 is fixedly connected to the rear end of the adjusting block 18.

When the first limit plate 8 is in the initial position, the position where its rear end corresponds to the scale line 17 is the zero scale position.

[0031] Furthermore, the end of the positioning block 20 away from the abutment plate 19 is aligned with the scale line 17 of the required bending angle. During the bending process of the steel bar, the touch switch 15 will gradually approach the abutment plate 19. When the touch switch 15 contacts the abutment plate 19, the motor 5 stops running.
