At this time, each part of the fabric can be uniformly elongated, and the stretching property of the fabric can be better tested. In addition, the difference of the moving distance of each fixing block 22 can be further provided to judge the uniformity of the stretching performance of the fabric along the length direction.
The fixing block 22 in this embodiment is provided with a plurality of spikes 23 on the side of the base plate 21. In particular, the length of the spikes 23 is small, but they penetrate well into the fabric, avoiding relative sliding between the fixed block 22 and the fabric.
The clamping device 20 in this embodiment further includes a fixing plate 26 fixedly disposed on the bottom plate 21; one end of an elastic piece far away from the fixed block 22 is provided with a tension meter; the plurality of tensiometers are fixedly connected to the fixed plate 26.
