[0027] The following will refer to Figures 1 to 5 The working principle of this utility model will be explained.

[0028] First, adjust the distance between the two fixing seats 61 according to the width of the headrest rod of the test headrest. Then, determine the position of the headrest along its length and fix the headrest rod with fixing screw 63. Next, adjust the tilt angle of the headrest by adjusting the angle part 7 and referring to the scale position pointed to by the pointer 9. Finally, measure the hardness of the car seat headrest. This invention is adaptable to various car seat headrests of different shapes and specifications. Regardless of differences in rod spacing, rod length, or installation angle, it allows for quick and accurate installation and positioning, greatly improving the versatility of tooling fixtures. This ensures precise positioning of the headrest during measurement, avoiding hardness measurement errors caused by positional deviations and improving the accuracy and reliability of measurement data. During operation, workers can easily and quickly adjust the fixture to the appropriate measurement position without complex operations or professional skills, significantly shortening test preparation time, improving testing efficiency, and reducing the cost of equipping different headrests with multiple tooling sets. One set of fixtures can meet the measurement needs of various headrests, reducing tooling procurement, storage, and management costs. It improves the accuracy of hardness measurement, providing reliable data support for the quality control of car seat headrests, and helps improve product quality and market competitiveness. The convenient operation and rapid adjustment significantly improve the efficiency of headrest hardness measurement, adapting to the rapid testing needs of large-scale production lines.
