[0024] The utility model provides Figure 1-3 A wiring harness fixing device shown in the figure includes a mounting bracket 1, a mounting bolt 2 is symmetrically slidably inserted and sleeved on the top of the mounting bracket 1, and the mounting bracket 1 can be installed on the wiring harness arrangement path through the mounting bolt 2. A wiring harness assembly 3 for fixing the wiring harness is arranged inside the mounting bracket 1, and the wiring harness assembly 3 includes a first arc plate 31, a second arc plate 32 and a protective gasket 33. The first arc plate 31 and the second arc plate 32 are symmetrically arranged inside the mounting bracket 1. The first arc plate 31 and the second arc plate 32 can cooperate to clamp and fix the wiring harness, and a connecting assembly 4 acting on the wiring harness assembly 3 is symmetrically arranged inside the mounting bracket 1. The connecting component 4 includes a mounting plate 41 and two limit springs 42. The mounting plate 41 is installed inside the mounting bracket 1, and the side of the wiring harness component 3 is slidably connected to the mounting plate 41. The limit springs 42 are slidably set inside the mounting plate 41, and the two limit springs 42 are respectively located on both sides of the wiring harness component 3. Therefore, when the wiring harness slides relative to the mounting bracket 1, the first arc plate 31 and the second arc plate 32 can move synchronously with the fixed binding part of the wiring harness between the two mounting plates 41, and under the action of the limit springs 42, the first arc plate 31 and the second arc plate 32 can drive the fixed binding part of the wiring harness to reset.

[0025] Furthermore, a fixing plate 34 is fixedly connected to the side of the first arc plate 31, and a mounting groove is opened on one side of the mounting plate 41. The outer wall of the fixing plate 34 is slidably sleeved with the inner cavity of the mounting groove. Under the action of the fixing plate 34, the first arc plate 31 and the second arc plate 32 can slide relative to the two mounting plates 41. The fixing plate 34 is located between the two limit springs 42. Therefore, after the first arc plate 31 and the second arc plate 32 slide with the wiring harness fixing part, the two limit springs 42 can give the fixing plate 34 a reset elastic force to move toward the middle of the mounting plate 41, so that the first arc plate 31 and the second arc plate 32 can drive the wiring harness fixing and binding part to reset, and the front side of the mounting plate 41 slides and intersperses. A guide rod 43 is sleeved, and the outer wall of the guide rod 43 is slidably sleeved with the limit spring 42. A through hole matching the guide rod 43 is opened on the front of the fixed plate 34, and a damping leather sleeve is fixedly sleeved in the inner cavity of the through hole. The outer wall of the guide rod 43 is slidably sleeved with the damping leather sleeve.
