After the test is completed, the driving source is suitable for driving the first clamping assembly and the second clamping assembly to move towards each other, thereby realizing the reset.

[0005] The clamping assembly used in the above-mentioned prior art is mainly composed of a bolt screwing and pushing type. Before clamping the textile fabric sample, the bolt needs to be loosened first to force the two clamping plates to separate and leave a gap. Then, one end of the textile fabric sample is placed in the gap. Finally, the bolt is tightened to clamp one end of the textile fabric sample. However, in actual operation, if the textile fabric sample is to be placed smoothly in the gap between the two clamping plates, the two clamping plates need to have a larger gap. Therefore, the bolt needs to be turned many times to produce a larger gap between the two clamping plates.
