After the fixed area is adjusted, place the workpiece to be detected on the workbench 2 and move the bent angle to the center of the angle ruler 5. Turn on the motor 8, which will drive the second gear 9 to rotate. The rotating second gear 9 will drive the first gear 7 engaged with it to rotate together with the screw rod 6. The rotating screw rod 6 will drive the connecting seat 10 threaded on its outer wall to move upward or downward together with the first base 11 and all the structural parts on the first base 11. When the first base 11 and the second base 12 move downward, the clamping plate 14 will tightly fix the workpiece to be detected. Move the angle ruler 5 forward and backward to make its position more consistent with the workpiece. The angle ruler 5 can be used to detect the bending angle. The angle ruler 5 includes a scale plate and a measuring ruler. The center of the scale plate is the base point. When the measuring ruler is rotated to be parallel to the bent edge of the workpiece, the degree of the bending angle can be determined by the position of the measuring ruler on the scale plate. The angle ruler 5 is a known technology and will not be described in detail here.

[0025] The device has the advantages of simple structure, reasonable design, fixed function, stable position of the workpiece to be detected, no position deviation during angle measurement, accurate and reliable detection data, easy to use, high practicality, and is suitable for promotion.
