[0002] In the wiring harness processing process, multiple cables need to be bundled, coiled and bundled and packaged through the wiring harness coiling device. Before the cable is wound, the cable head needs to be fixed by a clamping jaw mechanism. After one cable is wound, a new cable needs to be inserted again and wound according to the winding mode of the previous cable. However, when the clamping jaw mechanism fixes the new cable, it needs to be opened, which can easily cause the cable head of the previous cable to displace or loosen, and finally cause difficulty in bundling. In the prior art, two sets of clamping jaw mechanisms are usually used to alternately clamp the cable head. The two sets of clamping jaw mechanisms cooperate to fix the cable head of multiple cables, but the structure is complex, the overall equipment occupies a large area, and the two sets of clamping jaw mechanisms involve many parts, which has a high maintenance cost in the later period. Therefore, there is an urgent need to develop a clamping jaw mechanism that can clamp a new cable while ensuring that the clamped cable is fixed, so that multiple cables can be clamped uniformly to facilitate later bundling and packaging.
