[0020] Furthermore, a compression spring 9 is sleeved on the surface of the spring rod 10 , the top of the compression spring 9 is connected to the bottom of the buffer plate 8 , and the bottom of the compression spring 9 is connected to the top of the fixing plate 11 .

[0021] Furthermore, a sliding plate 18 is provided at the bottom of the inner side surface of the lower folding plate 7 , the bottom of the sliding plate 18 is located at the top of the buffer plate 8 , and the bottom of the upper folding plate 5 is located at the inner side surfaces of the two lower folding plates 7 .

[0022] Furthermore, a knob 17 is fixedly connected to the center of one side of the buffer plate 8, a rotating shaft 16 is provided at the bottom output end of the knob 17, the other end of the rotating shaft 16 is connected to one end of the bidirectional screw 13, a through hole 15 is opened at the center of one side of the buffer plate 8, and a rotating shaft 16 is provided at the through hole 15.

[0023] Working principle: When in use, the staff first places the hardware raw materials to be bent on the support plate 6, and then fixes the hardware raw materials. The fixing of the hardware raw materials is a prior art, and its specific structure will not be described in detail here. After the fixing is completed, the knob 17 is rotated according to the angle of the hardware raw materials to be bent as needed, so that the distance between the two lower folding plates 7 is equal to the distance between the bending angles of the required bending angle. After rotating the knob 17, the shaft 16 will rotate, and the rotation of the shaft 16 The rotation will cause the bidirectional screw 13 to rotate, and because of the unique characteristics of the bidirectional screw 13, the two sliding blocks 14 will move to the middle or both sides, thereby changing the distance between the two sliding blocks 14, and the distance between the lower folding plates 7 will be changed after the distance between the two sliding blocks 14 is changed.
