[0025] The portable harness mechanism includes a partition plate 7 and a limiting sleeve 8. The inner wall of the bottom end of the second upper shell 2 is provided with a partition plate 7 at the middle position. The limiting sleeve 8 is symmetrically and evenly installed inside the partition plate 7 and the second upper shell 2. A limiting piston rod 9 is slidably installed inside the limiting sleeve 8. A resistance spring 10 is connected between the limiting piston rod 9 and the inner wall of the bottom end of the limiting sleeve 8. The protruding end of the limiting piston rod 9 is arranged on the outside of the limiting sleeve 8, and the protruding end of the limiting piston rod 9 is connected to the outer wall of one side of the mounting back plate 11. The outer wall of the other side of the mounting back plate 11 is provided with a resistance tooth pad 12. When the wiring harness needs to be limited by resistance, At this time, you first need to engage the wiring harness in the middle position of the two interference tooth pads 12. At this time, the interference tooth pad 12 will automatically move to the side due to the squeezing force of the wiring harness, and then the movement of the interference tooth pad 12 will automatically drive the installation back plate 11 to move, and then drive the limiting piston rod 9 to slide inside the limiting sleeve 8. At this time, the interference spring 10 is squeezed by the limiting piston rod 9 and is in a contracted state. At the same time, the interference spring 10 is squeezed to generate a reaction force to synchronously push the limiting piston rod 9 to move. Then the movement of the limiting piston rod 9 will automatically drive the installation back plate 11 to move, and then drive the interference tooth pad 12 to tightly contact the outside of the wiring harness, thereby achieving the effect of limiting clamping the wiring harness.

[0026] The positioning and locking mechanism includes a limit groove 13, a positioning groove 14 and a limit block 15.

The side outer wall of the threaded ring 20 is provided with strip grooves at equal intervals, and the external thread of the threaded ring 20 is connected to the locking ring 21; when the wiring harness docking adjustment is completed, the locking ring 21 needs to be screwed to the outside of the threaded ring 20 to complete the fixation of the wiring harness.

[0028] When the utility model is in use, it is first necessary to pass the wiring harness through the placement groove 18 into the interior of the second upper shell 2, and based on this principle, the second adapter wiring harness is synchronously passed into the interior of the second lower shell 4, and then the two wiring harnesses are docked together according to the prior art. After the docking is completed, when the wiring harness needs to be limited by friction, it is first necessary to engage the wiring harness in the middle position of the two friction tooth pads 12. At this time, the friction tooth pad 12 will automatically move to the side due to the squeezing force of the wiring harness, and then the movement of the friction tooth pad 12 will automatically drive the installation back plate 11 to move, and then drive the limiting piston rod 9 to slide inside the limiting sleeve 8. At this time, the friction spring 10 is squeezed by the limiting piston rod 9 to be in a contracted state, and at the same time, the friction spring 10 is squeezed to generate a reaction force to synchronously push the limiting piston rod 9 Move, and then the movement of the limiting piston rod 9 will automatically drive the installation back plate 11 to move, and then drive the interference tooth pad 12 to tightly contact the outside of the wiring harness, so as to achieve the effect of limiting clamping of the wiring harness, and then when the first upper shell 1 and the first lower shell 3 are installed and closed, at this time, it is only necessary to engage the limiting block 15 into the inside of the limiting groove 13, and at the same time, the positioning block 16 is engaged with the inside of the positioning groove 14, so as to achieve the effect of clamping and fixing, and finally, when the first upper shell 1 and the second upper shell 2 are docked and installed with the first lower shell 3 and the second lower shell 4, it is only necessary to engage the interference card column 5 into the inside of the interference card groove 6 at the corresponding position, and the disassembly is the same. After adjusting the position of the wiring harness, screw the locking ring 21 to the outside of the threaded ring 20 to complete the fixation of the wiring harness.
