[0016] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] like Figures 1 to 3 As shown, a novel wire harness fixing device includes a main body 1, a strap 2, and a first base 3. One end of the strap 2 is embedded in the top of the first base 3, and the other end extends from one end of the main body 1 to the opposite end. The inner wall of the strap 2 is provided with teeth 21. The first base 3 is fixed to the bottom of the main body 1, and a magnet 32 ​​is fixed to the bottom of the first base 3. A locking mechanism is fixed to one end of the main body 1, and the locking mechanism engages with the teeth 21 on the inner side of the strap 2. Thus, without the need for drilling, the magnet 32 ​​at the bottom of the first base 3 can flexibly attract and fix the main body 1 to any ferrous carrier surface, avoiding damage to the overall structural strength of the carrier caused by drilling, thereby ensuring the overall structural strength of the carrier. Furthermore, the attraction characteristics of the magnet 32 ​​allow for flexible adjustment of the position of the main body 1 so that the strap 2 can fix the wire harness in the optimal fixing position.

[0018] like Figure 3 As shown, the top of the main body 1 is provided with multiple grooves, including a sliding groove 11, an embedding groove 12, and a locking groove 13. The sliding groove 11 is located in the middle of the main body 1 and extends from one side of the main body 1 to the other side. The locking groove 13 is located on one side of the main body 1, above the sliding groove 11, and communicates with the sliding groove 11. The embedding groove 12 is located on the top of the main body 1, above the sliding groove 11, and its two sides communicate with the sidewalls of the main body 1 via slots 121. Thus, by cooperating with the sliding groove 11, the embedding groove 12, and the locking groove 13 on the main body 1, the strap 2 has a flexible adjustment function. like Figure 3 As shown, the edge of the embedding groove 12 is provided with parallel protrusions 14, and one of the protrusions 14 has a through hole 141 communicating with the locking groove 13. Thus, the protrusions 14 have two effects: one is to provide a secure clamping effect for the strap 2 fixed in the embedding groove 12, making it less prone to shaking after the strap 2 is connected to the main body 1; the other effect is that a component that is linked to the locking groove 13 can be installed in the through hole 141 within one of the protrusions 14.

[0019] like Figure 3 As shown, a spring 142 is embedded in the through hole 141, and a bolt 143 is fixed at the edge of the through hole 141.

[0020] like Figure 3 As shown, a locking plate 131 is hinged within the locking groove 13, with one side of the locking plate 131 abutting against the spring 142 and the other side having protruding teeth 132 that mesh with the teeth 21; one end of the locking plate 131 protrudes outside the locking groove 13. Thus, through the cooperation of the locking plate 131 and the spring 142, the protruding teeth 132 at the front end of the locking plate 131 mesh with the teeth 21, thereby achieving the purpose of locking the strap 2.

[0021] Optionally, the tooth 21 shown has an inclined surface on one side facing the locking plate 131 and a right-angled surface on the other side; the protruding tooth 132 has an inclined surface on one side facing the insertion direction of the strap 2 and a right-angled surface on the other side. Thus, by the engagement of the inclined surface and the right-angled surface of the tooth 21 and the protruding tooth 132, when the strap 2 moves towards the locking plate 131, the inclined surfaces of both contact each other, and therefore it is not restricted by the locking plate 131. Conversely, when the strap 2 moves away from the locking plate 131, the tooth 21 contacts the right-angled surface of the protruding tooth 132, causing the tooth 21 and the protruding tooth 132 to lock together.

[0022] like Figure 3 As shown, one end of the strap 2 is provided with a plug-in end 22 adapted to the insertion groove 12, and both ends of the plug-in end 22 are provided with elastic buckles 23; wherein the elastic buckles 23 are engaged with the groove 121. In this way, when the plug-in end 22 is inserted into the insertion groove 12, the elastic buckles 23 on both sides are inserted into the insertion groove 12 at the same time as the plug-in end 22, and after the plug-in end 22 is fully inserted, its elastic buckles 23 are embedded in the groove 121, thus completing the fixing and locking of the strap 2, making it difficult for the strap 2 to detach from the main body 1.

[0023] Optionally, the cable tie 2 can be quickly replaced by engaging the elastic buckle 23 with the slot 121. For example, when the cable tie 2 is damaged and unusable, the damaged cable tie 2 can be removed by using a tool to push the elastic buckle 23 out of the slot 12, and a new cable tie 2 can be inserted into the slot 12. Alternatively, if the length or width of the cable tie 2 is insufficient to secure the wire harness, the cable tie 2 can be replaced accordingly.

[0024] like Figure 3 As shown, the first base 3 includes a connecting plate 31, a magnet 32, and a fixing rod 33. The magnet 32 ​​is embedded in the bottom of the connecting plate 31, and the connecting plate 31 is fixedly connected to the bottom of the main body 1 through the fixing rod 33. In this way, by utilizing the adsorption capacity of the magnet 32, the connecting plate 31 can be fixed to any adsorbent material surface such as iron, without the need to drill holes in the carrier to be fixed. This not only improves the flexibility of fixing the wire harness, but also avoids the impact of drilling on the overall structural strength of the carrier.

[0025] Alternatively, the material of magnet 32 ​​may include, but is not limited to, neodymium magnets.

[0026] like Figure 4 As shown, it also includes a second base 4, which consists of a fixed side clamp 41 and a movable side clamp 42. The fixed side clamp 41 is fixedly connected to the bottom of the main body 1, and a lead screw 43 is fixed to one side of the fixed side clamp 41. The movable side clamp 42 is disposed on one side of the fixed side clamp 41 and is slidably connected to the lead screw 43. The movable side clamp 42 has a fastening nut 44 that engages with the lead screw 43 on the side facing away from the fixed side clamp 41. Thus, when the carrier to be fixed is not suitable for adsorption by the magnet 32, the first base 3 can be replaced with the second base 4, which has a clamping and fixing function, further improving the flexibility of fixing the wire harness in this application.

[0027] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
