The clamping block 709 can be relatively close to work through the operation of the clamping motor 710, so as to achieve the clamping of the yarn. The fixed platform 704 can be moved up and down by driving the electric telescopic rod 701. A tension instrument is set on the fixed platform 704 to facilitate the fixing on the clamping block. The tensile strength test is performed on the test yarn on 709 and the fixed ring 508. When the wear resistance of the yarn needs to be tested, the yarn is passed through the test ring 607 and placed between the locking plate 503 and the adjusting knob 504. The adjusting knob 504 is tightened to fix the yarn on the locking plate 503. The frosted layer provided on the test ring 607 allows the yarn to contact the frosted layer of the inner ring of the test ring 607, and the operation of the yarn wear resistance test is realized by the up and down movement of the transmission pin 606.
