[0025] One end of the cylindrical tube 805 passes through the square plate 810 without a trapezoidal groove and is rotatably connected to the square plate 810, and the other end of the cylindrical tube 805 is rotatably arranged in the trapezoidal groove of the square plate 810 on the other side, and the side wall of the cylindrical tube 805 at one end located inside the trapezoidal groove is provided with sliding openings in a circular array at intervals, and the screw rod three 804 passes through the end of the cylindrical tube 805 away from the trapezoidal groove and is threadedly connected to the cylindrical tube 805, and a limiting ring 811 is fixed on the screw rod three 804, and the limiting ring 811 cooperates with the inner wall of the cylindrical tube 805, and the control ball 807 is fixed on the end of the screw rod three 804 close to the trapezoidal groove, and the circular plate 806 is slidably arranged inside the cylindrical tube 805, and the circular plate 806 is arranged on the side of the control ball 807 away from the screw rod three 804, and a spring two 812 is connected between the circular plate 806 and the inner wall of the trapezoidal groove of the square plate 810.

[0026] The locking balls 808 are arranged in a circular array in the sliding opening of the cylindrical tube 805 and are attached to the control balls 807. A fixing block 813 is fixed on the cylindrical tube 805, an electric telescopic rod 814 is fixed on the fixing block 813, and an extrusion column 815 is fixed on the transmission end of the electric telescopic rod 814.

[0027] The automatic rigidity detection mechanism 4 includes an electric cylinder 401, a rectangular block 402, an electric hydraulic cylinder 403 and an extrusion block 404. The electric cylinder 401 is symmetrically fixed on the top of the rectangular box 501, the rectangular block 402 is fixed on the transmission end of the electric cylinder 401, the electric hydraulic cylinder 403 is fixed on the bottom of the rectangular block 402, and the extrusion block 404 is fixed on the transmission end of the electric hydraulic cylinder 403.

[0028] During specific use, since there is a convex opening on the top of the protective cover 503, the parts are first passed through the convex opening and placed at the top center of the rectangular box 501. The convex opening facilitates the positioning of the parts. Then, the two protective covers 503 are simultaneously pushed to move toward the middle until the end faces of the two protective covers 503 are aligned. Then, the air pump 604 is started. The air pump 604 generates high-pressure gas in the rectangular space outside the partition 502 near the air pump 604. The high-pressure gas passes through the fixed tube 701 and the mobile tube 703 into the convex box 707 and the fixed box 708. When the convex box 707 and the fixed box 708 are filled with high-pressure gas, the air pump 604 can be turned off. The rectangular space outside the partition 502 near the air pump 604, the fixed tube 701, the mobile tube 703, the convex box 707 and the fixed box 708 are in a sealed state, and the convex box 707 and the fixed box 708 are filled with high-pressure gas When the screw rod 602 is rotated, the moving block 603 is threadedly connected to the two side walls of the screw rod 602 with opposite rotation directions. Therefore, when the screw rod 602 is rotated, the moving block 603 can move from both ends to the middle. The moving block 603 drives the fixed box 708 and the convex box 707 to move from both ends to the middle. The convex box 707 drives the moving tube 703 and the clamping ring 702 to slide into the fixed tube 701. The fixed box 708 drives the rectangular plate 711, the rectangular column 712 and the clamping block 713 to move from both ends to the middle until the clamping block 713 passes through the protective plate and clamps the two ends of the component, thereby fixing the end face of the component.If the component being fixed is relatively irregular, it is difficult to ensure the stability of the fixation by only fixing the two ends of the component. In this case, the screw rod 803 can be rotated first, and the screw rod 803 drives the convex block 802 to move downward. The convex block 802 drives the connecting block 809, the square plate 810, the columnar tube 805, the fixing block 813 and the electric telescopic rod 814 to move downward together, so that the electric telescopic rod 814 is adjusted to a suitable height. Then, the electric telescopic rod 814 can be directly rotated. After the electric telescopic rod 814 is rotated to a suitable angle, the electric telescopic rod 814 is kept in the state of being fixed. The screw rod 804 is kept still, and then the screw rod 804 is turned. The screw rod 804 drives the limit ring 811 and the control ball 807 to move gradually inward. The control ball 807 squeezes the locking ball 808 to move into the sliding opening and finally makes the outer wall of the locking ball 808 close to the inner wall of the square plate 810, so that the current position of the columnar tube 805 is locked, that is, the angle of the electric telescopic rod 814 is locked. Then the electric telescopic rod 814 is started, and the electric telescopic rod 814 drives the extrusion column 815 to move toward the top edge of the component until the extrusion column 815 presses the component tightly. The top of the component is fixed, and then the rigidity test of the component can be carried out. The electric cylinder 401 is started, and the electric cylinder 401 drives the rectangular block 402, the electric hydraulic cylinder 403 and the extrusion block 404 to move downward together until the extrusion block 404 is in contact with the top of the component. Then the electric hydraulic cylinder 403 is started, and the electric hydraulic cylinder 403 drives the extrusion block 404 to continue to extrude the component. When the two ends of the component are concave inward, the pressure of the end face of the component on the pressure sensor 705 on the clamping block 713 will change greatly. Magnet 706 is instantly energized and pulls control block 714 upward, squeezing spring 1 710. Once control block 714 is fully absorbed into rectangular tube 709, rectangular plate 711 is released from its restraint position and, driven by air pressure, moves toward clamping block 713. Rectangular plate 711 drives rectangular column 712 and clamping block 713 to move together, clamping and securing the component's end face. This prevents deviation during deformation and ensures stable fixation. After testing is complete, reset each component and turn off the power.
