High-capacity fiber stretching detection device

The utility model belongs to the technical field of textile measuring instruments, and particularly relates to a high-capacity fiber stretching detection device. The large-capacity fiber stretching detection device comprises a sample storage mechanism, the sample storage mechanism comprises a sample cage, a plurality of coaxially-arranged hollow adsorption strips are evenly distributed on the outer wall of the sample cage in the circumferential direction, a plurality of clamping devices are located on one sides of the hollow adsorption strips, and the sides, facing the clamping devices, of the hollow adsorption strips are provided with corresponding negative pressure holes corresponding to the clamping devices; when the same negative pressure hole keeps negative pressure, the fiber samples sucked into the holes are tensioned; and the sample loading mechanism is suitable for taking out the fiber sample and sending the fiber sample to the detection unit. According to the sample storage mechanism of the device,
