[0037] During operation, when it is necessary to clamp the steel bar, the multiple hydraulic push rods 17 inside the installation groove 15 can simultaneously push the upper clamp 4 and the lower clamp 6 to move, so that the two upper clamps 4 and the lower clamps 6 are respectively fitted with the outer sides of the steel bar to clamp and fix the steel bar, and then the clamp block 63 can be used to prevent the steel bar from slipping, and the sliding of the slide rod 18 and the inner wall of the groove 16 can prevent the upper clamp 4 and the lower clamp 6 from shaking when moving, thereby improving the stability of the structure and ensuring the tensile force detection effect of the steel bar.

[0038] Working principle: First, complete the assembly of the equipment, use the workbench 1 to ensure the stability of the fixed frame 2, fix the upper clamp seat 3 on the top beam of the fixed frame 2, and then install the lower clamp seat 5 on one side of the movable plate 7. Place the steel bar to be tested between the upper clamp seat 3 and the lower clamp seat 5. Use the multiple hydraulic push rods 17 inside the installation groove 15 to simultaneously push the upper clamp 4 and the lower clamp 6 to move and clamp the steel bar. Then use the PLC controller set on one side of the fixed frame 2 to control the two drive motors 13 to run simultaneously, and use the rotation of the drive motor 13 to drive the movable plate 7 to slide inside the slide groove 10, so that the movable plate 7 can be on the inner side of the fixed frame 2. The movable plate 7 moves downward, and uses the force generated by the downward movement of the movable plate 7 to perform tensile testing on the steel bar, and the PLC controller can record the tensile data of the steel bar in real time. When it is necessary to detect steel bars of different types, the clamp 63 needs to be replaced, and the fixing bolt 65 on one side of the limit plate 64 is rotated in the opposite direction to disengage the fixing bolt 65 from the upper clamp 4 and the lower clamp 6, and then the clamp 63 is pulled out, and the new clamp 63 is moved, and the trapezoidal block 62 is inserted into the trapezoidal groove 61.
