The other side of the positioning strip 4 is clamped on the outer wall of the connecting tube 2, one side of the connecting ring 3 is in contact with the outer wall of the connecting tube 2, one side of the fixed tube 1 is in contact with one side of the connecting ring 3, one side of the connecting ring 3 is in contact with the inner wall of the connecting sleeve 6, and the inner wall of the connecting sleeve 6 is rotatably connected to the outer wall of the connecting tube 2 through the limiting ring 5. Multiple groups of raised balls 8 are arranged in the middle of every two groups of limiting strips 4, one side of the limiting groove 7 is in contact with one side of the raised ball 8, and a supporting disc 9 is arranged inside the connecting tube 2, and the outer wall of the supporting disc 9 is fixedly installed on the inner wall of the connecting tube 2.

[0027] The following is a detailed description of the specific settings and functions of this embodiment. The hose exhaust pipe is threadedly connected to the threaded portion of the inner wall of one end of the connecting tube 2, and then the connecting ring 3 is sleeved on the other end of the connecting tube 2 so that the limiting strip 4 is in the groove on the outer wall of the connecting tube 2. Then, the connecting ring 3 is pushed to the right threaded end until the limiting strip 4 is completely set in the groove on the outer wall of the connecting tube 2. Then, the fixed tube 1 is pushed from left to right, and the groove on the inner wall of the fixed tube 1 contacts the outer wall of the limiting strip 4. When one side of the fixed tube 1 enters one side of the connecting sleeve 6, the connecting sleeve 6 is rotated, and the connecting sleeve 6 rotates on the outer wall of the connecting tube 2 through the limiting ring 5. The connecting sleeve 6 is installed together with the fixed tube 1 during the rotation process through the thread on the outer wall of the fixed tube 1. When the connecting sleeve 6 is firmly installed with the fixed tube 1, one side of the connecting ring 3 contacts one side of the fixed tube 1, and the other side of the connecting ring 3 contacts the inner wall of the connecting sleeve 6. The ball 8 and the limiting groove 7 are in contact with each other, so that the fixed pipe 1 and the connecting ring 3 will not rotate relative to each other, and the installation of the fixed pipe 1 and the connecting pipe 2 is completed. One end of the fixed pipe 1 is installed at the exhaust end of the automobile. By setting a plurality of sets of limiting strips 4, the fixed pipe 1 will be subjected to vibration and impact during driving. The limiting strips 4 can prevent the fixed pipe 1 and the connecting pipe 2 from rotating relative to each other, effectively reducing vibration and noise, and can also effectively prevent the fixed pipe 1 and the connecting pipe 2 from falling off, reduce the increased wear of the fixed pipe 1 and the connecting pipe 2 due to relative rotation, and extend the service life of the fixed pipe 1 and the connecting pipe 2. By setting the supporting disc 9, the connecting pipe 2 will be subjected to vibration and impact during driving, and the metal material of the connecting pipe 2 is prone to deformation or fatigue during long-term use. The supporting disc 9 can effectively support the connecting pipe 2 to keep it stable, reduce the deformation of the connecting pipe 2, and extend the service life of the connecting pipe 2.

[0028] Embodiment 2

[0029] like Figure 1 and Figure 3 As shown, two groups of sliding grooves 10 are opened on the outer wall of the connecting tube 2, and a sliding ring 11 is movably provided on the outer wall of the connecting tube 2. Two groups of sliding bars 12 are fixedly installed on the inner wall of the sliding ring 11. The two groups of sliding bars 12 are respectively arranged inside the two groups of sliding grooves 10. The sliding ring 11 is slidingly connected to the outer wall of the connecting tube 2 through the two groups of sliding bars 12. Two groups of sub-buckles 13 are fixedly installed on one side of the sliding ring 11, and two groups of female buckles 14 are fixedly installed on one side of the connecting sleeve 6. The two groups of female buckles 14 are respectively clamped with the two groups of sub-buckles 13, and the connecting sleeve 6 is movably connected to the sliding ring 11.

[0030] The effect achieved by the entire embodiment is that after the fixed tube 1 and the connecting tube 2 are installed together through the connecting sleeve 6, the sliding ring 11 is pushed to the left, and the sliding ring 11 drives the sliding bar 12 to slide on one side of the sliding groove 10, so that the sliding ring 11 drives the sub-buckle 13 to slide to the left. By setting the sub-buckle 13 and the female buckle 14, the sub-buckle 13 moves to the left and is clamped in the inside of the female buckle 14. Due to the cooperation of the sliding bar 12 and the sliding groove 10, the sliding ring 11 can only move in the horizontal direction. Therefore, after the connecting sleeve 6 and the sliding ring 11 are installed through the sub-buckle 13 and the female buckle 14, the rotation of the connecting sleeve 6 is restricted by the sliding ring 11, thereby ensuring that after the fixed tube 1 and the connecting tube 2 are installed, there will be no disconnection and leakage due to the rotation of the connecting sleeve 6. The connecting sleeve 6 plays a connecting and supporting role between the fixed tube 1 and the connecting tube 2. When the fixed tube 1 and the connecting tube 2 need to be disassembled, the sliding ring 11 is pushed to the right while pressing the sub-buckle 13 to disconnect it from the female buckle 14, so that the connecting sleeve 6 resumes rotation.

[0031] The method of use and working principle of the device are as follows: the hose exhaust pipe is threadedly connected to the threaded part of the inner wall of one end of the connecting pipe 2, and then the connecting ring 3 is sleeved on the other end of the connecting pipe 2 so that the limiting strip 4 is in the groove of the outer wall of the connecting pipe 2, and then the connecting ring 3 is pushed to the right threaded end until the limiting strip 4 is completely set in the groove of the outer wall of the connecting pipe 2, and then the fixed pipe 1 is pushed from left to right, and the groove of the inner wall of the fixed pipe 1 and the outer wall of the limiting strip 4 contact each other, and when one side of the fixed pipe 1 enters one side of the connecting sleeve 6, the connecting sleeve 6 is rotated, and the connecting sleeve 6 rotates on the outer wall of the connecting pipe 2 through the limiting ring 5, and the connecting sleeve 6 is installed with the fixed pipe 1 during the rotation through the thread of the outer wall of the fixed pipe 1. Together, after the fixed tube 1 and the connecting tube 2 are installed together through the connecting sleeve 6, push the sliding ring 11 to the left, and the sliding ring 11 drives the sliding bar 12 to slide on one side of the sliding groove 10, so that the sliding ring 11 drives the sub-buckle 13 to slide to the left, and the sub-buckle 13 moves to the left and is clamped inside the mother buckle 14. The rotation of the connecting sleeve 6 is restricted by the sliding ring 11, and one side of the connecting ring 3 contacts one side of the fixed tube 1, and the other side of the connecting ring 3 contacts the inner wall of the connecting sleeve 6. Multiple groups of raised balls 8 and limiting grooves 7 contact each other, so that the fixed tube 1 and the connecting ring 3 will not rotate relative to each other, then the installation of the fixed tube 1 and the connecting tube 2 is completed, and one end of the fixed tube 1 is installed at the exhaust end of the automobile.
