[0024] The limiting component 4 includes an installation ring 41. An electromagnetic ring 42 is installed on the inner wall of the installation ring 41 through bolts. And a fixing ring 43 is arranged inside the installation ring 41. Spring grooves 44 are formed on the inner wall of the fixing ring 43 and are distributed in an equidistant annular structure. And a moving rod 45 extending outside the fixing ring 43 is inserted into the spring grooves 44. A spring 46 is sleeved on the outer wall of the moving rod 45 located inside the spring grooves 44. And a positioning ring 47 is installed on the outer wall of one adjacent end of the moving rod 45 through bolts. The opening of the installation groove 3 can provide an installation position for the installation of the limiting component 4 and the positioning component 5. The setting of the installation ring 41 can provide an installation position for the installation of the electromagnetic ring 42. And the fixing ring 43 arranged at the center of the installation ring 41 provides a position for the limiting and fixing of the wire harness. When the electromagnetic ring 42 inside the installation ring 41 is started, the electromagnetic ring 42 will generate a magnetic force, and due to the magnetic connection with the connecting plate 48, the connecting plate 48 will drive the moving rod 45 to move. During the movement of the moving rod 45, the moving rod 45 will drive the fixing ring 43 to move, and the fixing ring 43 will move inside the fixing ring 43. Such a structure can facilitate the operator to disassemble the wire harness.

[0025] Please refer to Figure 2 and Figure 3 , the positioning ring 47 is arranged inside the fixing ring 43. And a connecting plate 48 is installed on the outer wall of the other end of the moving rod 45 far away from the positioning ring 47 through bolts. The setting of the connecting plate 48 can improve the moving function of the connecting plate 48 by using the magnetic connection with the electromagnetic ring 42, and can drive the moving rod 45 to move during the movement of the connecting plate 48. During the movement of the moving rod 45, the moving rod 45 can drive the positioning ring 47 to move inside the fixing ring 43.

[0026] Please refer to Figure 2 , Figure 3 and Figure 4, positioning components 5 are installed on both sides of the inner part of the mounting groove 3 near the mounting ring 41 by bolts, and the positioning component 5 includes a mounting plate 51, and the outer wall of one side of the mounting plate 51 is provided with jacks 52 that are equidistantly distributed in a horizontal structure. The setting of the positioning component 5 can provide assistance for the plug-in positioning of the wiring harness, and because the jacks 52 correspond to the fixing ring 43, it is convenient for the operator to plug and assemble the wiring harness, and the positioning component 5 and the limiting component 4 arranged inside the mounting groove 3 can provide installation positions for the installation of the positioning component 5 and the limiting component 4; the inner wall of the jack 52 is provided with moving grooves 53 that are equidistantly distributed in an annular structure, and a positioning spring 54 is inserted inside the moving groove 53. The opening of the moving groove 53 can position the installation position of the positioning spring 54, so that the positioning spring 54 will move inside the moving groove 53 during the extrusion process, and the device The setting of the positioning spring 54 can be used to provide power for the sliding of the auxiliary plate 56, so that the auxiliary plate 56 can slide inside the movable groove 53; one end of the positioning spring 54 is fixedly connected to the auxiliary plate 56, and an auxiliary wheel 55 extending to the inside of the fixing ring 43 is installed on the outer wall of the auxiliary plate 56 close to the socket 52 by bolts. When the auxiliary wheel 55 contacts the wiring harness, the wiring harness can drive the auxiliary wheel 55 to move. The auxiliary wheel 55 utilizes the fixed connection with the auxiliary plate 56 to enable the auxiliary plate 56 to move inside the movable groove 53. Such a structure enables the device to position the wiring harness when facing different wiring harnesses, and due to the action of the auxiliary wheel 55, the auxiliary wheel 55 can use the action of the bearing to reduce the friction of the wiring harness during the movement process, making the wiring harness plugging more labor-saving and time-saving, thereby improving the convenience of wiring harness installation.

[0029] Working principle: First, attach the housing 1 to the surface of the designated position on the car roof, and then use the threaded holes on the outer wall of the ear plate 2 and the bolts to fix the housing 1 to the outer wall of the designated position on the roof. At this time, insert the wire harness into the inside of the jack 52, and then the wire harness will contact the auxiliary wheel 55.

During the movement of the auxiliary plate 56, the auxiliary plate 56 and the auxiliary wheel 55 will slide inside the moving groove 53, and during the movement of the auxiliary plate 56, the auxiliary plate 56 can squeeze the positioning spring 54, and under the acting force of the positioning spring 54, the wire harness is always located at the center of the jack 52;

[0030] Then, start the electromagnetic ring 42. After the electromagnetic ring 42 is powered on, it will generate a magnetic force. The electromagnetic ring 42 drives the connecting plate 48 to move by using the magnetic connection with the connecting plate 48. During the movement of the connecting plate 48, the connecting plate 48 will drive the moving rod 45 to move. During the movement of the moving rod 45, it will squeeze the spring 46, and during the continuous movement of the moving rod 45, the moving rod 45 will drive the positioning ring 47 to move. Then, the wire harness can be passed through the inside of the fixing ring 43. During the continuous movement, one end of the wire harness will pass through the inside of another jack 52. At this time, turn off the electromagnetic ring 42 on the inner wall of the mounting ring 41. After the electromagnetic ring 42 is turned off, the magnetic force between the electromagnetic ring 42 and the connecting plate 48 will be disconnected. At this time, the spring 46 can use its contraction pressure to push the moving rod 45 to move. During the movement of the moving rod 45, the moving rod 45 will drive the positioning ring 47 to fit the surface of the material, and during the continuous movement of the moving rod 45, the moving rod 45 will drive the connecting plate 48 to move, thus realizing the fixing function of the wire harness. The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
