[0017] With the above structure, the carrier 1 is set up to facilitate movement, the adjusting plate 3 is set up to keep the sliding of the pair of positioning plates 7 stable, the bending plate 6 is set up to prevent the steel bar from bending when it is under force and comes into contact with the surface of the bending plate 6, and the groove 19 is set up to drive the shaping head 13 to be under force after it comes into contact with the surface of the steel bar, thereby driving the T-shaped shaft 14 to rotate.

[0018] Preferably, a torsion spring 18 is fitted on the surface of the T-shaped shaft 14, one end of the torsion spring 18 is fixedly connected to the inner wall of the cap 10, and the other end of the torsion spring 18 is fixedly connected to the surface of the T-shaped shaft 14. A controller 5 is fixedly connected to the surface of the carrier vehicle 1.

[0019] By setting the torsion spring 18, the shaping head 13 is reset as a whole. By setting the controller 5, an electrical signal is sent to control the movement of the output end of the electric telescopic rod 2.

[0020] Preferably, the inner wall of the adjusting plate 3 is rotatably connected to a positive and negative lead screw 9, one end of which is fixedly connected to a worm gear 12, the surface of the adjusting plate 3 is fixedly connected to a connecting plate 11, and the inner wall of the connecting plate 11 is rotatably connected to a worm 20, with the worm gear 12 meshing with the worm 20.

[0021] By setting the connecting plate 11, the rotation of the worm 20 is kept stable. By setting the worm 20, rotating the worm 20 drives the worm wheel 12 to rotate, which in turn drives the positive and negative lead screws 9 to rotate. By setting the positive and negative lead screws 9, the distance between a pair of positioning plates 7 is adjusted.

[0022] Preferably, the surface of the positioning plate 7 is threadedly connected to the surface of the positive and negative lead screws 9, and the upper surface of the support plate 21 is fixedly connected to the electric telescopic rod 2. The output end surface of the electric telescopic rod 2 is provided with multiple slots 8.

[0023] By setting the slot 8, which cooperates with the positioning pin 17, the connection and positioning are performed, thereby changing the stroke of the adjusting plate 3.

[0024] Preferably, a sleeve 15 is fixedly connected to the surface of the adjusting plate 3, and a positioning pin 17 is slidably connected to the inner wall of the sleeve 15. The positioning pin 17 is adapted to multiple slots 8.

When the surface of the groove 19 contacts the surface of the rebar, the shaping head 13 is forced to drive the T-shaped shaft 14 to rotate, the T-shaped shaft 14 drives the torsion spring 18 to twist and tighten, and the surface of the rebar is squeezed and shaped through the groove 19. When the operator needs to bend rebars with different degrees of bending, he can rotate the worm 20. The rotation of the worm 20 drives the positive and negative lead screws 9 to rotate through the worm wheel 12, adjusts the distance between the pair of positioning plates 7, and thus changes the distance between the pair of shaping heads 13. At the same time, the position of the adjusting sleeve 15 on the slot 8 can be slid and adjusted, and the positioning pin 17 is inserted into the corresponding slot 8, thereby changing the stroke of the adjusting plate 3 approaching the bending plate 6 to shape rebars with different degrees of bending.
