[0020] Through the above technical solution, during the process of bolt tightening, the rubber ring will deform so that the inclined surface gradually fits the engine surface. The inclined surface is used to increase the contact area between the rubber ring and the engine surface, saving raw materials while further enhancing friction and stability.

[0021] In one embodiment of the present invention, the locking element is configured as a cable tie.

[0022] Through the above technical solution, the fixing seat and the wiring harness are locked and fixed by the cable tie.

[0023] As described above, the vibration-resistant wire harness fixing device of the present invention has the following beneficial effects:

[0024] The elastic contact is placed between the fixed wire harness and the locking member during installation, the locking member is used to fix the wire harness and the elastic contact on the fixing base, so that the fixing of the wire harness is completed; during the working process of the engine, vibration occurs, at this time, due to the elastic contact force applied by the elastic contact to the locking member and the wire harness, a part of the vibration can be offset through elastic deformation during the engine vibration, so as to reduce the abrasion of the wire harness due to the vibration and improve the service life of the wire harness.
