[0023] Through the adaptation of ratchet wheel 1 3 and ratchet wheel 2 4 and the fixed connection between ratchet wheel 2 4 and the lower end of the stretching assembly 5, the stretching assembly 5 drives the ratchet wheel 2 4 to rotate during operation, thereby causing the ratchet wheel 1 3 to rotate. When the ratchet wheel 1 3 rotates, it drives the rotating shaft 1 21 to rotate, thereby driving the turntable 1 22 to rotate. Through the cooperation of the turntable 1 22 and the turntable 2 25, the turntable 2 25 rotates intermittently, and the digital display disk 26 rotates intermittently. When the toughness test of the polyester line is completed, the stretching assembly 5 is reset. At this time, the torsion spring 24 is automatically reset, and at the same time, the rotating shaft 1 21, the turntable 1 22 and the ratchet wheel 3 are driven to rotate in the opposite direction.

[0027] When the toughness of the polyester thread is tested, the cylinder 57 contracts, thereby driving a slider fixedly connected to the output end of the cylinder 57 to move in a direction away from the middle position of the workbench 12 and driving the connecting rod three 54 to move together, thereby causing the connecting rod two 53 to deflect.

[0029] When the test is completed, the two sliders 55 move closer to each other. In the process of the two sliders 55 moving closer to each other, when the push shaft 2 551 abuts against the push rod 611, as the slider 55 continues to move, the push shaft 2 551 pushes the push rod 611 to rotate downward on the connecting plate 121, and the spring 1 612 is stretched, so that the pawl 613 pushes the ratchet three 616 and the synchronous wheel 1 617 to rotate, and the synchronous wheel 2 618 and the turntable three 619 are rotated through the transmission action of the synchronous belt 6181, so that the intermittent feeding assembly 62 works and intermittent feeding is performed. When the feeding is completed, the two sliders 55 move away from each other. At this time, the spring 1 612 is reset. When the spring 1 612 is reset, the push rod 611 is pulled to rotate in the opposite direction until the push shaft 2 551 is separated from the push rod 611.

[0031] During the rotation of the turntable 3 619, when the hemispherical groove 6191 rotates to the position corresponding to the hemispherical block 6221, the spring 2 623 is reset. Under the action of the spring 2 623, the blocking rod 622 slides in the connecting hole 6211 toward the outside of the slide groove 621, so that the blocking rod 622 is separated from the lower end of the slider 2 624. The slider 2 624 falls under the action of gravity and separates from the slide groove 621. The two ends of the polyester line are clamped by the upper clamping block 626 and the lower clamping block 627 respectively, so that the slider Under the action of gravity, the guide rail 625, the upper clamp block 626, the lower clamp block 627 and the polyester thread slide onto the slider 1 55, and the upper clamp block 626 and the lower clamp block 627 abut against the top block 552. At the same time, the turntable 3 619 continues to rotate until the hemispherical block 6221 disengages from the hemispherical groove 6191 and stops. At this time, the spring 2 623 is compressed, and the other end of the blocking rod 622 extends from the connecting hole 6211 to prevent the next slider 2 624 from sliding downward. After the test is completed, the slider 2 624 is removed.
