At the bottom, the displacement ruler (66) is slidably installed inside the movable ruler groove (55), the pressure sensor (65) is electrically connected with the display meter (53), and the surface of the displacement ruler (66) is engraved with a scale . 10. The toughness detection device and detection method for steel processing according to claim 9, characterized in that: S1: placing the steel to be detected inside the fixed block (41), by rotating the clamping handle (44), The clamping screw (45) is rotated, the clamping block (46) is lowered, and the steel is clamped, so that the steel is clamped by the clamping device (4); S2: by pulling the rotating clamp (24), the rotating clamp (24) is positioned at the side of the supporting pad (23), and by rotating, the rotating clamping plate (24) is clamped on the supporting pad (23) On the side, the return spring (27) is compressed at this time, so that the clamping plate (26) moves into the inside of the limiting groove (22), and the clamping plate (26) moves out from the bottom of the fixed block (41); S3: by turning and pressing the turning hand wheel (61), the pressing screw rod (62) is rotated and descended, and the pressing block (63) is descended, and the pressure sensor (65) contacts the surface of the steel. At this time, record the displacement ruler ( 66) the location; S4: Continue to rotate and press the rotating handwheel (61), so that the pressure sensor (65) presses down on the steel, the steel is bent, and protrudes into the inside of the protective box (11), and the rolling wheel (43) is in the slide rail groove (33 ) is scrolled inside, and the detected data is displayed through the display table (53), and the pressure generated is recorded; S5: When the critical value is reached, when the steel breaks, stop the rotation, record the distance that the displacement scale (66) descends, understand the deformation of the steel when it breaks, and the pressure it bears when it breaks. When the steel breaks, reach the top and record The amount of pressure generated is reversely rotated and pressed to rotate the handwheel (61) to restore the steel to understand the deformation of the restored steel, thereby understanding the resilience of the steel; S6: By pulling the fixed handle (15), the falling trough (14) is moved out of the inside of the protective box (11), the broken steel is processed in a concentrated manner, and the clamping device (4) is manually moved to both ends, through Rotate and rotate clamp (24), back-moving spring (27) resets, and clamp plate (26) is clipped in the bottom of fixed block (41), prevents fixed block (41) from slipping in the inside of movable groove (32).
