[0037] Working principle: During detection, first start the drive motor 17, so that the screw rod 16 moves with the sliding frame 18, so that the sliding frame 18 moves to one end of the base 1, so as to prevent the detection component 7 from affecting the worker's placement of the fasteners on the two clamping components 4.

For the purpose of detecting fasteners of different specifications, the fasteners can be tested later by operating the hydraulic cylinder 5 so that another clamping assembly 4 can tighten the fastener to achieve a tension test on the fastener. After the tension test is completed, the drive motor 17 can be operated to start so that the screw rod 16 moves with the two sliding frames 18, so that the distance sensor 19 detects different positions of the fastener. Subsequently, the length of the inner groove of the sliding frame 18 minus the data detected by the two distance sensors 19 can be used to obtain the diameter of the fastener to determine whether the fastener is deformed during the tension test. In addition, as the drive motor 17 moves, the acoustic wave detector 20 will be started, so that the acoustic wave detector 20 can detect the fastener to detect whether there are defects such as cracks inside the fastener after the tension test, thereby greatly improving the versatility of the tooling.
