In this example, the guide wheel 12 is I-shaped to guide and limit the wiring harness, and a plurality of wire clamping grooves 22 are provided on the front of the positioning rod 2, and the wire clamping grooves 22 correspond to the winding plate 3. The wiring assembly includes a terminal block 16, and the terminal block 16 is fixedly installed in the cabinet body 1, and a plurality of wire inlet pipes are provided at the bottom of the terminal block 16, and a conductive plate 17 is fixedly installed on the back of the terminal block 16. In this example, the cable positioning mechanism also includes a limit rod 5, and an adjustment groove 21 that penetrates the positioning rod 2 is provided on one side of the wire clamping groove 22 in the positioning rod 2, and the adjustment groove 21 is connected to the wire clamping groove 22. The limit rod 5 is movably installed in the adjustment groove 21, and a chamber 4 that is connected to the adjustment groove 21 is opened on the left side of the adjustment groove 21 in the positioning rod 2. A gear 7 is rotatably installed on one side of the chamber 4, and a plurality of tooth grooves 11 that mesh with the gear 7 are opened on one side of the limit rod 5. A gear 7 that meshes with the gear 7 is rotatably installed on one side of the chamber 4. The meshing block 8 has a handle connected to the upper end of the connecting shaft of the block 8 outside the positioning rod 2. One side of the block 8 is connected to the inner wall of the chamber 4 by a spring 9. The limiting rod 5 is provided with a limiting block 6 near the side of the wire clamping groove 22. The arrangement of the wire arrangement and positioning mechanism can facilitate the positioning and fixing of the wire harness, and the strength of the wire harness clamping and fixing can be adjusted as needed. The excess wire harness can also be wound and distributed between several guide wheels 12 on the side of the winding plate 3, so that the wire harness can be arranged and sorted to avoid being scattered. In this example, the wiring assembly also includes a pressure plate 18, and the pressure plate 18 is arranged on the side of the conductive plate 17 in the wiring seat 16. One end of the pressure plate 18 is connected to a support rod 19, and one end of the wiring seat 16 is connected to a handle outside the wiring seat 16. The outer side of the support rod 19 is provided with a spring 20 on the side of the pressure plate 18 away from the conductive plate 17. The arrangement of the wiring assembly can complete wiring conveniently and quickly. In this example, a plurality of slide grooves 23 are provided on the front of the winding plate 3, and the slide grooves 23 correspond to the guide wheel 12. A slide rod 13 is provided in the slide groove 23, and a slider 14 and a spring 2 15 are provided on the outside of the slide rod 13. The slider 14 is located in the slide groove 23 near the edge of the winding plate 3. The connecting shaft of the guide wheel 12 is rotatably connected to the slider 14 so that the guide wheel 12 can drive the slider 14 to slide and squeeze the spring 2 15 after being subjected to force, thereby buffering the force on the guide wheel 12 and enabling it to support the wire harness and tighten it to avoid looseness.

[0023] In this example, the limiting rod 5 is L-shaped, and the limiting block 6 has an arc groove on the side corresponding to the wire clamping groove 22. Both the arc groove and the wire clamping groove 22 are provided with a rubber layer. A fixing rod 10 is fixedly mounted on one side wall of the chamber 4. The fixing rod 10 is located on the side of the clamping block 8 near the front of the positioning rod 2 to clamp and fix the wire harness. The use of the fixing rod 10 can limit the position of the clamping block 8. In this example, the side of the pressure plate 18 near the conductive plate 17 is provided with several rubber strips with a semicircular cross-section to increase friction between the pressure plate 18 and the wire harness, thereby improving the compression and fixing effect.

[0024] The working principle of the present invention is as follows: when in use, the connecting shaft of the card block 8 is driven to rotate by twisting the handle, so that one end of the card block 8 is separated from the gear 7. At the same time, the card block 8 will squeeze the spring 1 9, and then the limit rod 5 can be pulled to drive the limit block 6 to move, so that the limit block 6 and one end of the limit rod 5 are moved out of the positioning rod 2, and then the force applied to the handle is released, so that the card block 8 is reset under the elastic force of the spring 1 9, so that the card block 8 is meshed with the gear 7, and then the wiring harness to be arranged can be stuck in the wire clamping groove 22, and then the limit rod 5 is pushed to drive the limit block 6 to move to one side of the wire clamping groove 22, so that the limit block 6 moves into the clamping groove. When the gear 7 is in the line groove 22, the tooth groove 11 on one side of the limit rod 5 will drive the gear 7 meshing with it to rotate, and the gear 7 will continuously squeeze and push the meshing block 8 to rotate to the outside of the gear 7. At the same time, the block 8 will squeeze the spring 19. When one end of the block 8 meshing with the gear 7 moves to the outside of the block 8, the gear 7 continues to rotate until the teeth of the gear 7 squeezing the block 8 are misaligned with the block 8. The block 8 will reset under the elastic force of the spring 19, so that the block 8 and the gear 7 are meshed. This cycle repeats until the limit rod 5 drives the limit block 6 to clamp and fix the wiring harness in the wire groove 22. If you need to adjust the limit block 6 The harness clamping force can continue to push the limit rod 5 to fix the harness, increase the clamping force of the harness, thereby improving the fixing effect, easy to use, and can quickly clamp and fix the harness. While using the two positioning rods 2 to limit and fix the harness, the excess length of the harness can be circuitously passed through the side of several guide wheels 12 in sequence, so that it can squeeze and push the guide wheel 12 on one side, so that the guide wheel 12 will drive the slider 14 to slide along the slide rod 13 and squeeze the spring 2 15, so that the force generated by the deformation of the spring 2 15 can buffer the force on the guide wheel 12, so that the guide wheel 12 can support the harness and prevent it from being loose. The device can quickly arrange and position the wiring harness, improve the efficiency of arranging the wiring harness, improve work efficiency, and make it more convenient to use; after the wiring harness is arranged and positioned, wiring can be carried out, and the corresponding handle is pulled to drive the support rod 19, and then the pressure plate 18 is driven away from the conductive plate 17. At the same time, the pressure plate 18 will squeeze the spring three 20, and then pass one end of the wiring harness through the wire inlet tube to the wiring seat 16, and then the force applied to the handle can be released, so that the pressure plate 18 is reset under the elastic force of the spring three 20, so that the pressure plate 18 will cooperate with the conductive plate 17 to press the wiring harness, and the quick wiring process can be completed, which is more practical.
