[0002] In electronic devices, electrical facilities, and various industrial applications, the use of cables is ubiquitous. The fixation and protection of cables are crucial for ensuring the normal operation of circuits. Traditional sealing and insulating rubber sleeves are mostly used for sealing and isolating the interfaces of wires and cables to prevent moisture erosion and external damage, and at the same time play a certain role in fixing and maintaining the wires and cables. However, there are many deficiencies in the prior art in practical applications.

[0003] Firstly, the existing cable fixation methods often difficult to simultaneously meet the requirements of tightness and easy operation, or additional tools and components are required for cable fixation, which not only increases the installation complexity but also raises the cost. Secondly, the heat dissipation problem of cables is also an issue that cannot be ignored. For wires and cables in a closed or semi-closed state, poor heat dissipation often leads to excessive temperatures, which may affect the cable performance, shorten the service life, and even pose safety hazards.

For this purpose, the utility model provides a sealing and insulating rubber sleeve, which solves the problems that the traditional sealing and insulating rubber sleeve is difficult to fix the wire harness and difficult to dissipate heat from the cable.

A knob is rotatably connected to the outside of the arc-shaped frame, the knob passes through the side wall of the arc-shaped frame and is fixedly connected with a wire wheel, and a rope is fixedly connected between the wire wheel and the rotating rod.

[0010] Furthermore, a plurality of wire slots are fixedly connected to the outside of the fixing frame, and the wire slots gradually narrow from inside to outside.
