DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The utility model will be further described below in conjunction with the drawings and embodiments.

[0019] Please refer to Figures 1 to 4 , a general-purpose flexible fixture for seat skeletons, including a base 1, and the base 1 stably supports all components. Two front support columns 2 and two rear support columns 3 are fixed on the top of the base 1, and their main tasks are to support the front end of the seat skeleton track to ensure its stability and accuracy. At the same time, the rear support column 3 is responsible for supporting the rear end of the seat skeleton track, forming a stable support system with the front support column 2.

[0020] A key component, the first positioning component 4, is assembled at the top of the rear support column 3. This component consists of a first positioning rod 41, a first spherical blocking portion 42, and a first spring 43. The first positioning rod 41 is slidably connected inside the rear support column 3, and its top protrudes skillfully from the top of the rear support column 3, facilitating alignment with the mounting holes of the seat frame track. The spherical blocking portion 42 at the bottom of the rod not only increases stability but also works in conjunction with the first spring 43 to provide flexible buffering for the positioning rod 41. In this way, even if the positioning rod 41 is not fully aligned with the mounting hole, damage caused by excessive extrusion can be avoided.

[0021] At the top of the front support column 2, a mounting seat 5 is fixed. Inside this mounting seat 5, several second positioning components 6 are assembled. The design of these components is equally ingenious and consists of a sliding sleeve 61, a positioning hole 62, a positioning post 63, a second positioning rod 64, a second spherical blocking portion 65, and a second spring 66. The sliding sleeve 61 is slidably connected inside the mounting seat 5, and the positioning hole 62 on its sidewall fits tightly with the positioning post 63 on the sidewall of the mounting seat 5. This design enables the height of the sliding sleeve 61 to be adjusted flexibly, thus adapting to the hole positions of the mounting holes of seat frame tracks of different models. When the positioning post 63 is inserted into the positioning hole 62, the sliding sleeve 61 is fixed at the highest position, and at this time, the second positioning rod 64 inside it participates in positioning. When the positioning post 63 is pulled out from the positioning hole 62, the sliding sleeve 61 will drop under its own gravity, causing the top of the second positioning rod 64 to move downward and no longer participate in positioning. This ingenious design greatly improves the versatility and flexibility of the inspection tool.

[0022] In addition, columns 7 are installed at all four corners of the base 1, and clamps 8 are installed at the tops of these columns. These clamps are arranged facing the front support column 2 and the rear support column 3, and can effectively fix the track of the seat frame on the support columns, ensuring stability and accuracy during the inspection process.

[0023] To facilitate the handling and movement of this relatively heavy inspection tool, lifting rings 9 are installed at all four corners of the top of the base 1. The design of these lifting rings enables the inspection tool to be easily transported by a crane, greatly improving work efficiency and convenience.

[0024] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformations made using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present invention.
