[0002] With the development of society and the rapid progress of economy, more and more cars are entering the homes of ordinary consumers. The automotive wiring harness is the network body of the automotive circuit. The connection, power supply, signal transmission, etc. between various components all require the use of wiring harnesses. In order to ensure that the wiring harness will not be bent or worn during use, rubber protective covers are usually used to wrap the wiring harness. Therefore, the role of these small components in the car cannot be ignored.

[0003] After searching, a car trunk door wiring harness rubber sleeve is disclosed in the announcement number: CN203151014U, and its technical solution is: it is composed of a corrugated tube located in the middle, clamping rings located at both ends and a connecting bent tube connecting the corrugated tube and the clamping rings. The special feature is that the waveform of the longitudinal section of the corrugated tube is a broken line shape, and the connection between adjacent broken lines has a smooth transition. The advantages of the utility model are as follows: 1. The corrugated geometric shape of the bellows is changed from an arc connection to a fold line and a smooth transition connection between adjacent fold lines, which greatly improves the elongation and compression rate of the bellows; 2. The connection angle between the connecting elbow and the clamping rings at both ends is increased, so that the wiring harness runs smoothly in the wiring harness rubber sleeve, which is convenient for disassembly and assembly of the wiring harness; 3. Transition fillets are designed at the edges of the clamping platform of the clamping ring, which is convenient for installation and will not cause poor assembly due to changes in sheet metal thickness or deformation; 4. The protruding edge design of the clamping groove is conducive to waterproofing and sealing; 5. The wiring harness fixing tongue set at the clamping ring at one end is removed, and the double tongue is changed to a single tongue to avoid deformation of the clamping ring after bundling the wiring harness.

[0004] The protective cover in the above application is usually a cylindrical structure with a fixed aperture size, which cannot provide effective fixation for the wiring harness. At the same time, the protective cover will be deformed under the force of collision or pulling, affecting the protection and fixation effect of the wiring harness. Utility Model Content

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the automobile wiring harness is passed through the outer ring, and then the handle is rotated to drive the rotating ring fixedly connected thereto. The inner gear arranged on the outer side of the rotating ring and the outer gear arranged on the inner side of the outer ring can be rotated and fixed at will through interference fit. The rotation of the rotating ring will drive the slide rod to move with the help of the slide groove, thereby driving the sliding block to move between the fixed blocks, so as to change the distance between the sliding blocks to adapt to automobile wiring harnesses of different sizes. At the same time, the automobile wiring harness can also be fixed to prevent the automobile wiring harness from being entangled or moved.
