[0008] In order to better support the position of the framework pin assembly groove, the groove bottom of the supporting groove is in a concave arc shape that matches the framework pin assembly position.

[0009] In order to achieve a better bending effect and improve structural rationality, the push block includes a fixed block connected to the bending cylinder piston part. Two pin push parts are arranged on the side of the fixed block away from the bending cylinder piston part.
