[0022] Specifically, by setting a limit rod 105 at the top of the spur plate 104 for limiting, the stable sliding of the spur plate 104 is effectively guaranteed, avoiding the structural tilt, resulting in expansion problems and affecting the accuracy.

By measuring the distance at this time, it is possible to calculate whether the quality of the wire harness is qualified, and finally the device can be maintained regularly.
