[0002] When wearing clothes, friction will occur between clothes and between clothes and external objects, which will cause varying degrees of wear and even damage to the clothing fabric (fabric). The wear resistance of fabric is the ability of fabric to resist friction and wear. The wear resistance of fabric directly determines its use and the type of clothing, and also determines the wearability and service life of clothing. Therefore, the detection of the wear resistance of fabric or clothing is of great significance for the selection and design of clothing fabric (fabric), the acceptance and guarantee of clothing quality, and the transaction pricing of clothing and fabric.

Slide grooves 4 are provided on both sides of the load-bearing plate 1 and close to its lower end. Slide blocks 6 are fixedly provided on both sides of the tension plate 5. The two slide blocks 6 slide within the corresponding slide grooves 4 respectively. The slide blocks 6 slide in the slide grooves 4 to improve the stability of the movement of the tension plate 5. A nut 11 is fixedly provided at the upper end of the load-bearing plate 1 and close to the middle. The adjusting rod 9 is threadedly connected to the nut 11 through a threaded section 10. The adjusting rod 9 is threadedly connected to the nut 11 through the nut 11 and the screw thread. The function of the groove segment 10 is to move the adjusting rod 9 when it is rotated. A receiving groove 12 is provided inside the bearing plate 1 and located at the rotating seat 8. The rotating seat 8 is received through the receiving groove 12. The two clamping blocks 14 are respectively clamped in the corresponding clamping grooves 16 to fix the jacket 15 on the bearing plate 1.
