The outer surface of the seat body 3 is snapped into contact with the inner part of the base 2. The inner side wall of the pulling frame 7 is fixedly connected with a second electric telescopic rod 19. The telescopic end of the second electric telescopic rod 19 is fixedly connected with a top plate 20. By providing the second electric telescopic rod 19, it can be extended and retracted after power is turned on, thereby controlling the distance between the top plate 20 and the seat body 3, thereby cooperating with the pulling frame 7 to facilitate the firm clamping of the backrest of the seat body 3.

By providing the anti-slip pads 21, the friction force of the back of the top plate 20 and the inner wall of the pull frame 7 can be increased respectively, thereby facilitating the firm clamping of the backrest of the seat body 3 and making it difficult for the backrest of the seat body 3 to slide out of the clamp.

[0022] The telescopic end of the first electric telescopic rod 5 is fixedly connected to the pull plate 6, and a closed pull shell 8 is provided inside the pull frame 7. The two side surfaces of the main frame 1 are fixedly connected to the mounting plates 14. The upper surface of each mounting plate 14 is provided with a plurality of identical mounting holes 15. By providing the mounting holes 15, the mounting plates 14 can be firmly installed in conjunction with the external bolt structure, thereby stabilizing the main frame 1 and other internal structures for stable use.

[0023] The front of the closed pull shell 8 and the back of the pull plate 6 are fixedly connected with a pull rope 9. The inner wall of the pull frame 7 is fixedly connected with two guide rods 11 and a pressure sensor 13. The outer surface of each guide rod 11 is slidably connected to the interior of the closed pull shell 8. The first electric telescopic rod 5, the pressure sensor 13 and the second electric telescopic rod 19 are electrically connected to the button controller 4 through wires. The inner bottom wall of the main frame 1 is fixedly connected with a U-shaped bracket 16, and the inner wall of the U-shaped bracket 16 is fixedly connected with a support rod 17. By providing the U-shaped bracket 16, it is convenient to raise the support rod 17. By providing the support rod 17, a rotation base surface can be provided for other roller structures, thereby increasing the movement stability of the pull rope 9.

[0024] The outer surfaces of the two guide rods 11 are slidably connected to the pressure plate 10. The outer surface of each guide rod 11 is sleeved with a return spring 12. The front of the pressure plate 10 contacts the back of the pressure sensor 13. The two ends of each return spring 12 respectively contact the inner wall of the closed pull shell 8 and the back of the pressure plate 10. The outer surface of the support rod 17 is rotatably connected to the guide wheel 18. The inner wall of the guide wheel 18 contacts the outer surface of the pull rope 9. By providing the guide wheel 18, it can rotate around the outer surface of the support rod 17, thereby providing a stable support structure for the pull rope 9, facilitating the stable pulling of the pull rope 9.

[0025] The working principle of the present utility model is: use external bolts and other structures to cooperate with the mounting holes 15 to firmly assemble the mounting plate 14, then stably clamp the seat body 3 to be tested inside the card seat 2, and then, when the button controller 4 controls the second electric telescopic rod 19 to retract, place the pull frame 7 on the seat back of the seat body 3, and control the second electric telescopic rod 19 to extend again when operating the button controller 4, until the top plate 20 cooperates with the pull frame 7 and the anti-slip pad 21 to firmly clamp the seat body 3, then ensure that the outer surface of the pull rope 9 is close to the inner wall of the guide wheel 18, operate the button controller 4 to control the extension and retraction of the first electric telescopic rod 5, and then control the pull rope 9 to rotate back and forth around the outer surface of the guide wheel 18 under the connection of the pull plate 6, so that the backrest of the seat body 3 will be repeatedly pulled. During this period, the closing pull shell 8 slides along the outer surface of the guide rod 11 and cooperates with the pressure plate 10 to compress the return spring 12. During this period, the pressure of the pressure plate 10 on the pressure sensor 13 also changes continuously, and the change in pressure on the pressure sensor 13 will be reflected in real time through the button controller 4. The button controller 4 can also record the range of pressure change on the pressure sensor 13. In this way, the fatigue resistance of the backrest of the seat body 3 is measured while measuring the pressure change range it can withstand, thereby increasing the detection function of the detection tooling. The design of the entire EPP car seat back detection tooling effectively solves the problem that the detection function is limited due to the lack of a tension detection structure for real-time monitoring of the seat back tension.
