When the detection piece is pre-clamped, because the tensile test is performed on the detection piece, when the detection piece is stretched, the detection piece drives the elastic roller 13 to rotate through the contact surface, and the rotation of the elastic roller 13 drives the roller 1 61 to rotate, and the roller 1 61 rotates through the circumferential surface and the circumferential surface of the roller 2 63. The two rollers 63 are in contact with each other, thereby driving the two rollers 63 to rotate. The rotation of the two rollers 63 drives the reciprocating screw 62 to rotate.

When the top of the test piece is clamped, the bottom of the test piece is placed inside the movable plate 5. At this time, the electric telescopic rod 9 is started through the main console to start working. The electric telescopic rod 9 drives the clamping claw 10 to rotate through the top hinge point, so that the two clamping claws 10 are close to each other to clamp the bottom of the test piece, which speeds up the testing process, improves the overall testing efficiency, and reduces the possibility of unexpected situations during testing, thereby improving the safety and reliability of the entire testing process.

The device is accurate and makes the detection more stable, which improves the overall work efficiency.

The movement of the fixed block three 74 drives the buckle 75 to move. At the same time, the right electric clamp block 8 drives the card plate 76 to move, so that the movement of the card plate 76 drives the buckle 75 to rotate through the inclined surface and then resets through the torsion spring, thereby limiting and strengthening the electric clamp block 8, avoiding loosening of the test piece during clamping, improving the stability of the test, ensuring the safety of the staff during the test, and also accelerating the test process and improving the test efficiency; the circumferential surface of the bidirectional threaded rod 71 is rotatably connected to the inner wall of the push plate 68.

While clamping the top of the test piece, the rear electric clamp block 8 drives the third fixed block 74 to move. The movement of the third fixed block 74 drives the buckle 75 to move. At the same time, the right electric clamp block 8 drives the clamping plate 76 to move, so that the movement of the clamping plate 76 drives the buckle 75 to rotate through the inclined surface and then resets through the torsion spring, thereby limiting and strengthening the electric clamp block 8, avoiding loosening of the test piece during clamping, improving the stability of the test, ensuring the safety of the staff during the test, and also accelerating the test process and improving the test efficiency.
