[0031] As Figs. 1-3As shown, the embodiment provides a non-metal material clamping tool configured to clamp a non-metal material sample 100. The non-metal material clamping tool comprises a fixed frame 1, a movable plate 2 and an adjusting member 3, wherein the fixed frame 1 is provided with a first contact 11 opposite to the movable plate 2, at least two second contacts 21 opposite to the first contact 11 are provided on the movable plate 2 in a spaced manner, and the non-metal material sample 100 is clamped and fixed between the first contact 11 and the second contact 21, wherein the orthographic projection of the first contact 11 is located between the two second contacts 21, specifically, one side of the non-metal material sample 100 provided with a prefabricated crack 101 abuts against the second contact 21, and the adjusting member 3 is connected with the movable plate 2 and configured to adjust the height between the movable plate 2 and the first contact 11. When assembling, the non-metal material sample 100 is placed between the first contact 11 and the second contact 21, so that the first contact 11 and the second contact 21 preliminarily fix the non-metal material sample 100, and then the adjusting member 3 is adjusted, the movable plate 2 gradually approaches the first contact 11, the two second contacts 21 lift the two ends of the non-metal material sample 100 upward, and the first contact 11 abuts against the middle region of the non-metal material sample 100, so as to clamp the non-metal material sample 100 and bend it. Without using a special bending and clamping device, the non-metal material sample 100 can be clamped in a bent state, so that when the fatigue performance of the non-metal material sample 100 is evaluated, a specific type of oven does not need to be used, thereby greatly reducing the equipment cost of the non-metal material fatigue performance evaluation. At the same time, by controlling the adjusting member 3, the distance between the movable plate 2 and the first contact 11 can be controlled, so as to control the bending degree of the non-metal material sample 100.

[0032] Exemplarily, the thickness of the first contact 11 is 5mm-10mm, and the thickness of the second contact 21 is 5mm-10mm. In this way, the size of the reaction force between the first contact 11 and the second contact 21 and the non-metal material sample 100 is in a suitable range, which further improves the stability of the clamping of the first contact 11 and the second contact 21 on the non-metal material sample 100, and further ensures the accuracy of the fatigue performance result of the non-metal material sample 100. As a preferred, the first contact 11 comprises a first circular arc part, and the second contact 21 comprises a second circular arc part, wherein the first circular arc part abuts against the upper end surface of the non-metal material sample 100, the second circular arc part abuts against the lower end surface of the non-metal material sample 100, and the prefabricated crack 101 on the non-metal material sample 100 is arranged on the lower end surface. In this way, without damaging the non-metal material sample 100, the force is relatively more concentrated at the place where the first contact 11 and the second contact 21 contact the non-metal material sample 100, which further ensures that the bending state of the non-metal material sample 100 meets the experimental requirements. Exemplarily, the diameter of the first circular arc part is 5mm-10mm, and the diameter of the second circular arc part is 5mm-10mm.

Specifically, the movable plate member 2 is arranged above the second horizontal plate 13, an internal thread is arranged on the positioning hole 131, and an external thread is arranged on the adjusting member 3. When the adjusting member 3 is rotated, the adjusting member 3 gradually lifts the movable plate member 2, so that the movable plate member 2 gradually approaches the first contact 11, and the non-metallic material sample 100 clamped between the first contact 11 and the second contact 21 is bent. The threadedly connecting of the adjusting member 3 with the positioning hole 131 can ensure that the adjusting member 3 always lifts the movable plate member 2, and the stability of clamping the non-metallic material sample 100 by the non-metallic material clamping tool is ensured. In this embodiment, the adjusting member 3 can be selected as a bolt.

When the distance between the movable plate member 2 and the first contact 11 is adjusted by adjusting the adjusting member 3, the connecting column 14 plays a guiding role in the movement of the movable plate member 2, so that the height of the movable plate member 2 is adjusted more stably. When the non-metallic material clamping tool is assembled, one end of the connecting column 14 can be connected with the first horizontal plate 12 first, then the other end of the connecting column 14 is connected with the second horizontal plate 13 after being threaded through the guide hole 222 on the movable plate member 2, and then the adjusting member 3 is installed, so that the adjusting member 3 abuts against the movable plate member 2 after being threaded through the positioning hole 131 on the second horizontal plate 13. In this embodiment, the connecting column 14 can be fastened and connected with the first horizontal plate 12 and the second horizontal plate 13 by bolts.

Specifically, in the embodiment, the main plate 22 and the side plates 23 are an integral structure, which further improves the stability of the movable plate member 2 as a whole.

[0037] Preferably, the first contact 11 is located at the center of the two spaced second contacts 21 in the orthographic projection, so that the non-metallic material sample 100 is more uniformly stressed during clamping, and the bending state of the non-metallic material sample 100 is more in line with the experimental requirements. Specifically, the prefabricated crack 101 on the non-metallic material sample 100 is arranged at the center position along the length direction, and the first contact 11 abuts against the center of the non-metallic material sample 100 along the length direction during clamping of the non-metallic material.
