[0003] The Chinese patent authorization announcement number is CN217304694U, and the name is a steel bar strength tester, which includes a workbench, and two first clamping blocks are driven to move in opposite directions by two cylinders, so that two side plates are moved in opposite directions, and the steel bars are clamped and limited to prevent the steel bars from being offset and tilted when the hydraulic rod is driven. The hydraulic rod is pressed down to display the value through the digital display device to detect the strength of the steel bar. The side plates, sleeve rods, sliding rods and springs play a buffering role, and the steel bars are limited, so that the device is suitable for use with steel bars of different sizes, and it is more convenient to use;

[0004] The shortcomings of the above-mentioned existing technical solution are: although the above-mentioned solution can fix steel bars of different sizes, the fixing position is the bottom of the steel bar. When the hydraulic rod continuously applies pressure to the steel bar, the stability of the steel bar is poor, which can easily cause the top of the steel bar and the bottom of the hydraulic rod to be misaligned and slipped, affecting the normal progress of the detection work and easily causing damage to the device.
