[0020] 1. By fixing the clamp ring on the positioning column, when fixing the wire harness, first insert the positioning column into the hole of the car sheet metal, and then the wire harness can be clamped into the clamp ring. After the wire harness is clamped into the clamp ring, the port abutment part will press the wire harness tightly into the clamp ring. The overall structure is simple and easy to use;

[0021] 2. By arranging a reinforcing arm in the clamping ring, the two ends of the reinforcing arm are respectively connected to the port abutment and the bottom of the clamping ring. In use, the reinforcing arm will apply an inward tensioning force to the port abutment, thereby increasing the compression force of the port abutment on the wire harness, making it difficult for the wire harness to fall out of the clamping ring. At the same time, the reinforcing arm will increase the elastic force of the clamping ring and enhance the overall stability of the wire harness fixation;

[0022] 3. By setting an inner abutment on the inner side of the clamp, when in use, the inner abutment will cooperate with the port abutment to tighten and fix the wire harness, thereby improving the stability of the wire harness. An elastic groove is opened at the position corresponding to the inner abutment, which can effectively improve the elasticity of the inner abutment. The two ends of the inner abutment are connected to the reinforcing arms on both sides, which can apply an inward pulling force to the reinforcing arms on both sides to improve the holding force of the wire harness.

[0027] The inner side wall of the snap ring 2 is integrally formed with a port abutment 21, an inner abutment 22 and a reinforcing arm 23. The port abutment 21 is provided with two portions located at the two ends of the snap ring 2 close to the ring opening 3, and the port abutment 21 is an arc-shaped structure arched toward the inside of the snap ring 2; the inner abutment 22 is located at one end of the inner side of the snap ring 2 close to the positioning column 1, and the inner abutment 22 is an arc-shaped protrusion arched toward the inside; two reinforcing arms 23 are provided corresponding to the port abutment 21, and the reinforcing arms 23 are respectively located on both sides of the snap ring 2, and the two ends of the reinforcing arms 23 are respectively connected to the port abutment 21 and the inner abutment 22 on the same side. Elastic grooves 24 are provided on the snap ring 2 at the positions corresponding to the port abutment 21 and the inner abutment 22, so that the port abutment 21 and the inner abutment 22 are arched structures arched toward the inside.

[0028] When the wiring harness is clamped, the reinforcing arm 23 will apply an inward pulling force to the port abutment 21, so that the port abutment 21 can be tightly pressed against the wiring harness; at the same time, the reinforcing arm 23 will increase the elastic performance and structural strength of the clamping ring 2, so that the clamping ring 2 can hold the wiring harness tightly; the two ends of the inner abutment 22 are connected to the reinforcing arm 23. During use, the inner abutment 22 will pull the reinforcing arm 23 inward, thereby increasing the inward tightening force of the reinforcing arm 23, thereby increasing the fixing stability of the clamping ring 2 to the wiring harness.

[0029] Biting teeth 25 are integrally formed on the inner walls of the port abutting portion 21 and the inner abutting portion 22. When the wire harness is fixed, the biting teeth 25 increase the friction force on the wire harness and improve the stability of fixing the wire harness.
