The wire clamping mechanism 9 includes an insert block 91, a clamping block 92, a pressure rod 93, a spring 94 and a pressure cover 95. The clamping block 92 is fixedly arranged on the top of the insert block 91, the pressure rod 93 is clamped on the inner side of the clamping block 92, the spring 94 is arranged between the clamping block 92 and the pressure rod 93, and the pressure cover 95 is connected to the clamping block 92 by screws.

[0026] Specifically, the measuring mechanism 10 includes an adjusting seat 101, a pushing plate 102, a measuring rod 103 and a screw 104. The adjusting seat 101 is clamped on the inner side of the support frame 1, the pushing plate 102 is set at one end of the top of the pull plate 5, the measuring rod 103 is fixed on the top of the adjusting seat 101, and the screw 104 is fixed on the outside of the adjusting seat 101. One end of the screw 104 passes through and extends to the outside of one side of the support frame 1. A waist-shaped hole is opened on the side of the support frame 1 to match it. The surface of the screw 104 A locking nut is provided, and a push plate 102 is sleeved on the outside of the measuring rod 103. The bottom of the push plate 102 is in contact with the upper surface of the adjustment seat 101. A scale is provided on the surface of the measuring rod 103. A latch is provided on the top inner side of the clamping block 92. A tooth groove is provided on the inner side of the pressure cover 95 to cooperate with it.

A pressure plate is provided at one end of the pressure rod 93, and a limiting plate is provided at the other end.

[0027] After the thread ends are clamped, the thread ends are wound around the surface of the pressure rod 93 and the end thread ends are clamped to the tooth position at the inner top of the clamping block 92. After the thread ends pass through the groove at one end of the pressure plate of the pressure rod 93, they are clamped into the arc groove in the middle of the tooth. Then, the pressure cover 95 is installed. The tooth groove inside the pressure cover 95 and the tooth position at the inner top of the clamping block 92 clamp the end of the thread ends.

Then, the oil cylinder 3 is started to extend to lift the height of the pulling plate 5. The lifting seat 4 effectively guides the lifting of the pulling plate 5. During the stretching process, the tension sensor 6 will perform real-time statistics on the magnitude of the tension until the polyester yarn is broken. The oil cylinder 3 stops extending. At this time, the height to which the pushing plate 102 is lifted on the surface of the measuring rod 103 is the maximum stretching length of this section of polyester yarn.
