The support column 3, support rod 5, and first pin 7 facilitate the fixing of the support rod 5, simplifying installation. The upper end of the support column 3 has first limiting holes 4 on all sides. The support rod 5 is connected through the middle of the support column 3. Several second limiting holes 6 are opened at the lower end of the support rod 5. The upper end of the support column 3 is connected through the first pin 7, which passes through the support rod 5. A limiting ring is fixedly connected to the top of the support rod 5. 8. A threaded rod 9 is fixedly connected to the top of the support rod 5, and a nut 10 is threadedly connected to the top of the threaded rod 9. A rectangular plate 11 is set at the top of the limiting ring 8. By setting the rectangular plate 11 and the T-shaped groove, the hollow groove design of the rectangular plate 11 allows the seat 13 arch frame to be well connected to the testing machine through the threaded rod 9 and the nut 10. At the same time, the long T-shaped limiting groove 12 allows the seat 13 to slide, providing the possibility of adapting to different lengths and models of seat 13, avoiding strict requirements on the fixed equipment, improving the convenience of testing, and preventing waste release paper from hindering the adhesive. The rectangular plate 11 is fixed to the upper end of the support rod 5 through the threaded rod 9 and the nut 10.

[0028] The rectangular plate 11 has T-shaped limiting grooves 12 at both the front and rear of its top end. A seat 13 is provided at the top of the rectangular plate 11, and a rivet screw 14 passes through the bottom of the seat 13. By using the rivet screw 14 and drilling holes at the nose and tail of the seat 13, the seat 13 is fixed with screws and nuts. This method effectively overcomes the limitation of traditional clamps being unsuitable for adhesive bow frames, ensuring that the seat 13 will not deform or break due to uneven force during tensile testing, thus guaranteeing the reliability of the test results. The rivet screw 14 passes through the T-shaped limiting groove 12, and the seat 13 is fixed by the rivet screw 14. At the top of the rectangular plate 11, a bracket 15 is fixedly connected to the top left and right ends of the workbench 1. A first electric telescopic rod 16 is provided inside the bracket 15. The bottom end of the first electric telescopic rod 16 is fixedly connected to the workbench 1. A top plate 17 is fixedly connected to the top end of the first electric telescopic rod 16. A second electric telescopic rod 18 is fixedly connected to the top end of the top plate 17. A connecting rod 19 passes through the bottom end of the second electric telescopic rod 18. A second pin 20 passes through the upper end of the connecting rod 19. A spring clip 21 is fixedly connected to the bottom end of the connecting rod 19.

[0029] When using this invention, before starting the test, the user must ensure that the testing machine is level and prepare the bicycle saddle 13 to be tested and the corresponding fixing tools. The saddle 13 is placed on the rectangular plate 11, which is made of iron. The fixture is made of high-strength material to ensure its durability and reliability during long-term use. This feature allows the equipment to withstand frequent testing operations, ensuring the consistency and accuracy of test results. It ensures a perfect fit between the saddle 13's arch support and the hollowed-out groove. The position of the rectangular iron is adjusted to suit the specific model of the saddle 13 and the distance to the testing machine. This step requires careful attention to ensure a secure connection between the two components to guarantee the accuracy of subsequent tests. Use a drilling tool to drill holes at the nose and tail of the seat cushion 13, ensuring accurate positioning and appropriate depth. Insert screws and tighten them with nuts to ensure a stable connection between the seat cushion 13 and the rectangular iron block. Connect the testing equipment to the fixed nose and tail of the seat cushion 13, adjust the tensile test parameters, start the testing equipment, and gradually apply tension. Observe and record the performance of the seat cushion 13 under different tensions, paying particular attention to any deformation or damage during the tensile process and recording it in detail for later analysis. After the test, organize and analyze the test data, comparing it with standards to evaluate the tensile strength of the seat cushion 13. Data analysis software can be used to visualize the tensile strength of different seat cushions 13, providing data support for the R&D team. Compared with traditional testing methods, the main advantages of this fixture are its wide adaptability, ease of operation, and economy. By adapting its design to different models of the cushion 13, this product can meet diverse market demands, rather than being limited to a specific type of cushion 13. This flexibility allows product developers to conduct diverse tests in a shorter time, improving work efficiency.
