[0031] One end of the accessory is located at the upper end of the protruding portion 2, and the other end of the accessory is located below the pressing plate 3. When the pressing plate 3 is pressed down, the accessory can be fastened between the pressing plate 3 and the protruding portion 2, thereby bending the accessory into an L shape.

[0032] Specifically, by rotating the eccentric shaft 4 to drive the pressing plate 3 to press down the bending fitting, the overall structure is simple and effective, easy to operate, and avoids vise clamping interference to hinder bending, making bending difficult and difficult to get into place. The avoidance gap ensures that the fitting can be bent at a right angle, avoiding incomplete bending due to the thickness of the fitting.

[0033] In this embodiment, the bracket includes two vertical plates, which are respectively located on both sides of the pressure plate 3, and both ends of the rotating shaft of the eccentric shaft 4 are rotatably connected to the two vertical plates.

[0034] Specifically, the eccentric shaft 4 is supported by the vertical plate, and the eccentric shaft 4 is arranged above the pressing plate 3 to limit the activity space of the pressing plate 3, thereby preventing the pressing plate 3 from rotating at will.
