The design of the arc-shaped convex edge can be bent in combination with the shape of the terminal and the force point, and the other side of the two profiling blocks 1 5 has an extended edge protruding upward along the edge, forming an L-shape.

[0023] In this embodiment, the adjustment mechanism is arranged on the adjustment seat 11, and is used to adjust the position of the two L-shaped bending plates 24. The adjustment mechanism includes a rotating rod 15 rotatably connected to the adjustment seat 11, and two worms 16 are fixedly connected to the rotating rod 15.
