[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] refer to Figures 1-4 As shown, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: A protective device for the steering support wiring harness of an automobile dashboard, including a corrugated pipe 1 and a corrugated pipe 3 arranged opposite to each other. A male connecting pipe 2 is fixedly provided at one end of the corrugated pipe 1, and a female connecting pipe 4 is provided on the corrugated pipe 3 to cooperate with the male connecting pipe 2 for fixation. The corrugated pipe 1 and the corrugated pipe 3 are made of PP material, and the male connecting pipe 2 and the female connecting pipe 4 are made of rigid PVC material. Fixing components are provided on the outer wall of both the corrugated pipe 1 and the corrugated pipe 3.

[0027] like Figures 1-5 As shown, a portion of the male connecting pipe 2 and the female connecting pipe 4 extends outside the corrugated pipe 1 and the female connecting pipe 4. The extended end of the male connecting pipe 2 is fixedly connected to a limiting block 7, and the extended end of the female connecting pipe 4 is provided with a slot 6 for the limiting block 7 to enter. The upper end of the limiting block 7 is provided with a sliding groove 8, and a slider 9 is slidably provided in the sliding groove 8.
