In the traditional flexible circuit board bending process, an operator sucks and places the flexible circuit board on a jig table by using a suction pen, and manually bends the flexible circuit board by using a pressing pen. Because the product size is less relatively, the operator bare-handed operation is difficult to ensure the required precision, has the error in the size, and bend radius also can't guarantee simultaneously, leads to bend radius undersize very easily and makes the flexible circuit board cross the book, and the circuit board breaks. The machining precision and the machining efficiency of the product are low, and the production and manufacturing cost is increased.

In this embodiment, the elastic member 313 is a spring. The tail end of the second bending head 32 is provided with a limiting protrusion to prevent the second bending head 32 from separating from the accommodating cavity, so that the second bending head 32 moves back and forth in the accommodating cavity. The first bending head 31 and the second bending head 32 are arranged in parallel or substantially in parallel. The tip of the first bending head 31 is closer to the product fixing unit 10.

Specifically, the first bending head 31 includes a vertical surface 311 at the trailing end of the first pressing head, and an inclined surface 312 extending obliquely upward from the upper end of the vertical surface 311.
In response to the first handle 237 moving from the top end of the second section 392 of the first position-limiting hole 39 to the bottom end of the second section 392 of the first position-limiting hole 39, the vertical surface 311 contacts the first fold 1 of the product, and bends the first fold 1 of the product a by 90 degrees. In response to the first handle 37 moving from the right side of the first section 391 of the first position limiting hole 39 to the left side of the first section 391 of the first position limiting hole 39, the inclined surface 312 pushes the first bevel 1 to bend back 180 degrees to the first bevel 1.

The area where the limiting wall 115 and the fixing surface 113 are combined is provided with a bending fillet 116, so that the phenomenon that the product is broken due to the fact that the bending angle is too small can be avoided.
