A pull plate 2 is installed on the inner side of the connecting plate 102. The pull plate 2 is located below the top plate 1 and supports the bottom of the car seat leather. A roller 201 is installed on the inner side of the pull plate 2. Both ends of the roller 201 are connected to a rotating shaft 202. One end of the rotating shaft 202 is connected to the pull plate 2. The roller 201 is rotatably connected to the pull plate 2 via the rotating shaft 202. A first clamping plate 204 is connected to the lower end of the pull plate 2 to connect the upper end of the car seat leather. A second clamping plate 303 is installed at the lower end of the top plate 1 to connect the lower end of the car seat leather. A weight 205 is also connected to the lower end of the pull plate 2 as a gravity pulling mechanism when the leather is stretched.

[0026] A groove 1021 is provided on the inner surface of the connecting plate 102. Slider blocks 203 are connected to both sides of the pull plate 2. The sliders 203 slide in conjunction with the groove 1021. The pull plate 2 can move longitudinally using the sliders 203 and the groove 1021, thus facilitating longitudinal stretching of the leather and maintaining the stability of the pull plate 2 during longitudinal movement. A tension sensor 1022 is connected to the top inner surface of the groove 1021. One end of the tension sensor 1022 is connected to the slider 203. The pull plate 2 moves downward under the pulling force of the weight 205. When in motion, the slider 203 moves down synchronously along the slide groove 1021. At this time, the slider 203 exerts a downward pulling force on the tension sensor 1022, thereby generating a tension value. A movable plate 3 is installed at the lower end of the top plate 1. A slide rod 301 is connected to the upper surface of the movable plate 3. A slide rail 105 is provided on the bottom surface of the top plate 1.

[0030] A roller 201 is installed on the inner side of the pull plate 2. The roller 201 can rotate in conjunction with the rotating shaft 202. One end of the leather can be wound around the roller 201, and the winding position can be adjusted according to the stretching position of the leather. The position that does not need to be stretched is wound and hidden, while the stretching position is exposed. The remaining part after winding is fixed by the first clamping plate 204, so that the leather can be subjected to segmented stretching test or local targeted test. The operation is highly controllable and the test accuracy is high. The pull-down mechanism of the pull plate 2 is a weight 205. In practical applications, the weight of the weight 205 can be replaced to generate different tensile values ​​from the tension sensor 1022, thereby adapting to different testing needs of automotive seat leather.
