Background At present, the textile detection industry generally needs to cut a whole cloth into small samples with different sizes before sample detection is carried out, so as to meet the requirements of different detection projects. For example, the test items such as the strength test, the abrasion resistance test, and the air permeability test have different requirements for the sample size, and some test items have the same size and some test items have different sizes. Therefore, the same cloth needs to be cut for multiple times to obtain multiple groups of samples with different specifications. The existing cutting mode mainly depends on manual operation, and common tools comprise scissors and a part of single-specification pressing type cutter (such as a disc sampler). The pressing type cutter (circular sampler) is usually used for cutting circular samples, and although the efficiency of a part of the pressing type cutter can be improved, the size cut by the circular sampler is fixed, and the requirement of cutting samples with multiple specifications cannot be met. When the detection task amount is large, frequent replacement of the sample cutter can lead to low cutting efficiency, and increase of the working intensity and time cost of operators. In addition, the current cutting device that fabrics detected is generally single in structure, lacks the modularized design, can't realize the quick switch of multiple size in a flexible way on an equipment, is difficult to satisfy the efficiency and the convenience demand of detection mechanism in many specifications cuts.
