Reinforcing steel bar strength detection device

The utility model discloses a reinforcing steel bar strength detection device which comprises a detection assembly, the detection assembly comprises a servo motor, an output shaft, a driving wheel disc, a chain, a driven wheel disc, a threaded rod, a sliding block and a threaded hole, and the output end of the servo motor is fixedly connected with the output shaft. Driving wheel discs are fixedly connected to the front portion and the rear portion of the outer side wall of the output shaft. Two ends of a reinforcing steel bar are respectively placed in reinforcing steel bar placing grooves in two lower limiting cylinders, so that the reinforcing steel bar is conveniently clamped and fixed, an output shaft is driven to rotate through a servo motor, so that two threaded rods are driven to rotate, detection wheels on two sliding blocks are pushed to be close to the reinforcing steel bar in the middle of an operation table at the same time, and detection accuracy is improved. The anti-skid grooves in the two dete
