[0026] Working principle: When in use, the staff prepares multiple mounting seats 15 in advance, and installs the fasteners to be tested on each mounting seat 15 in turn, and starts the servo motor 4. The servo motor 4 drives the turntable 5 to rotate through the output end. The rotation of the turntable 5 drives the swing arm 6 to rotate.
