With the advancement of science and technology and economic development, people's requirements for the comfort, economy and safety of automobiles are constantly increasing, the types of electronic products in automobiles are increasing, and automobile wiring harnesses are becoming more and more complex.

[0003] When the wire harness is in use, in order to ensure the stability of its connection end and reduce the space occupied by the wire harness, the wire harness is generally arranged and gathered, and then fixed with a fixed buckle or tape and other structures, and at the same time, a protective cover structure is provided to protect the wire harness. However, after the wire harness is fixed, the wire harness lacks buffer space, which makes it easy for the wire harness to break internally after being pulled by the outside world. Therefore, after the wire harness is fixed in position, it needs to have a certain movable angle to achieve protection of the wire harness. To this end, the utility model proposes a wire harness with a fixed buckle to achieve improvement on the above problem. Utility Model Content
