[0030] Example 2

[0031] See also Figures 1 to 6 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the positioning structure can be provided to play an auxiliary positioning role after the limiting pressure plate 63 rotates.

[0032] Specifically, a circular shaft hole 631 corresponding to the T-shaped shaft seat 64 is formed on one end surface of the limiting pressure plate 63, and a positioning structure is provided between the circular shaft hole 631 and the T-shaped shaft seat 64.

When the limiting pressure plate 63 rotates, the positioning protrusion 643 will be squeezed and deformed first, causing the positioning protrusion 643 to be squeezed out of the positioning slot 632 in the initial position. At this time, the limiting pressure plate 63 rotates normally. When the limiting pressure plate 63 rotates one hundred and eighty degrees around the T-shaped shaft seat 64, the end of the positioning protrusion 643 will be squeezed into another positioning slot 632, thereby having the effect of auxiliary limiting the limiting pressure plate 63, that is, when the limiting pressure plate 63 rotates to the top of the wiring harness positioning plate 5, it has the effect of auxiliary positioning. At the same time, when the limiting pressure plate 63 is rotated away from the top of the wiring harness positioning plate 5, it can also be assisted in limiting by the positioning protrusion 643.
