The outer surface of the first insulating layer 1 is installed with the rubber layer 2. The first insulating layer 1 provides a fixing point for the rubber layer 2 installed on its outer surface. At the same time, the first insulating layer 1 is made of insulating plastic material to prevent static electricity from contacting the gas. The rubber layer 2 is connected to the outer surface of the first insulating layer 1 to provide a fixing point for the second insulating layer 3, the metal mesh 12 and the plastic metal wire 13 installed on its outer surface and inside. The outer surface of the rubber layer 2 is installed with the second insulating layer 3. The second insulating layer 3 is made of insulating plastic material. The outer surface of the three groups of fireproof layers 5 are all covered with fixing rings 6, and the fixing rings 6 are covered with the outer surface of the fireproof layer 5 to provide fixing points for the fixing rods 7 installed on the top. Three groups of fixing rods 7 are installed on the top of the fixing rings 6, and the fixing rods 7 are installed on the top of the fixing rings 6 to provide connection points for the extension rods 8 connected to the inner side thereof, and at the same time provide fixing points for the springs 9 installed inside thereof. The outer surface of the fixing rods 7 is wrapped with the extension rods 8, and the extension rods 8 are connected to the inner side of the fixing rods 7. The fixing plate 10 installed at the rear end thereof provides a fixing point. A spring 9 is installed inside the fixing rod 7, and the rear end of the spring 9 is connected to the interior of the extension rod 8. The spring 9 is installed inside the fixing rod 7. When the impact force in the external environment is transmitted to the interior of the extension rod 8, the spring 9 undergoes elastic deformation to absorb the impact force, thereby improving the safety of the sleeve after being fixed. A fixing plate 10 is installed at the rear end of the extension rod 8. The fixing plate 10 is installed at the rear end of the extension rod 8 to provide a fixing point for the threaded fixing hole 11 opened through the top thereof.

Before using the device, insert the external bolt into the threaded fixing hole 11, and insert the external bolt into the external fixing plane to complete the fixation of the sleeve. Three groups of metal meshes 12 are arranged inside the inner wall of the rubber layer 2. The metal meshes 12 are installed inside the inner wall of the rubber layer 2, thereby improving the structural strength of the sleeve. Two groups of plastic metal wires 13 are arranged inside the inner wall of the rubber layer 2, and the plastic metal wires 13 are located on the inner side of the metal meshes 12. The plastic metal wires 13 are installed inside the inner wall of the rubber layer 2. When the sleeve is bent, the plastic metal wires 13 are bent, thereby improving the use experience of the sleeve.
