[0029] Further, the number of fixed frame 311 is two, and the fixed frame 311 is arranged on the outer wall of the first support plate 3114 and the second support plate 321 respectively, so that the two ends of the yarn can be fixed at the same time, and then the side fixed frame 311 is driven to move, so that the elasticity detection can be carried out.

[0030] Furthermore, the inner wall of the first slot 312 fits snugly with the outer wall of the insert block 314, and the inner wall of the second slot 313 fits snugly with the outer wall of the winding rod 315. This ensures that the insert block 314 and the winding rod 315 are tightly fitted on the inner walls of the first slot 312 and the second slot 313, thereby ensuring their connection stability.

[0031] Furthermore, an arc setting is provided at the bottom end of the second pressure plate 3113, and the bottom end of the second pressure plate 3113 is in a semi-wrapped state and fits against the top end of the winding rod 315, so that the bottom end of the second pressure plate 3113 can be tightly fitted against the top end of the outer wall of the winding rod 315, thereby ensuring the stability of the winding line during the detection process.

[0032] The testing mechanism 32 includes a second support plate 321 fixedly connected to the top of the workbench 1, and the outer wall of the second support plate 321 is threadedly connected to the second screw rod 322.

When the fixed frame 311 moves, the limit block 323 can be driven to move on the inner wall of the limit slide groove 324. In this way, the yarn can be pulled by the movement of the fixed frame 311 on one side, and then the elastic coefficient of the yarn can be detected by the tension sensor 325.
