of the rubber ring 301 at the inner wall of the groove 7, when the upper clamp powder 4 and the lower clamp powder 5 respectively continue to drive the fixing frame 801 to approach the positions of the connecting pipe 1 and the connecting bent pipe 2, the fixing frame 801 can drive the extrusion block 805 to move towards the inner wall of one end of the groove 7 close to the position of the radial fixing component 3 through the movable sleeve 802 and the hinged rod 804, and the movable sleeve 802 extrudes the damping spring 803 until the upper clamp powder 4 and the lower clamp powder 5 are assembled, at this time, under the action of resetting and stretching of the damping spring 803, the damping spring 803 can be matched with the hinged rod 804, the extrusion block 805 and the groove 7 through the movable sleeve 802 to axially fix the connecting pipe 1 and the connecting bent pipe 2, prevent the connecting pipe 1 and the connecting elbow 2 from generating axial vibration due to loose connection, namely reduce the noise generation caused by the axial vibration of the connecting pipe 1 and the connecting elbow 2, and simultaneously, through the matching of the movable sleeve 802 and the damping spring 803, the axial vibration of the connecting pipe 1 and the connecting elbow 2 can be buffered, thereby further reducing the noise generation, when the upper clamp powder 4 and the lower clamp powder 5 approach each other, the positioning rod 905 can be inserted into the inner wall of the positioning pipe 903 to play a role in guiding and positioning, when the upper clamp powder 4 and the lower clamp powder 5 are completely attached to form a complete circular structure, the fixing ring 906 is rotated and the fixing ring 906 is sleeved on the surface of the positioning pipe 903, thereby primarily completing the assembly of the upper clamp powder 4 and the lower clamp powder 5, at this time, the twisting block 616 is rotated, and the twisting block 616 drives the worm 603 to rotate, the worm 603 drives the clockwise rotation ring 605 to rotate through the worm wheel 604, so that the rotation ring 605 drives the movable block 610 to move on the inner wall of the second movable groove 609 through the movable rod 607, and the movable block 610 stretches the fixed block 611 while pressing the limit groove 612, the movable block 610 injects the air inside the limit groove 612 into the communicating chamber 308, and the communicating chamber 308 is matched with the air inlet hole 307 and the air inlet pipe 306, so that the air enters the inside of the second cavity 303, and the air is in the inside of the first cavity 302 and the second cavity 303 through the communicating pipe 305, and drives the rubber ring 301 to expand, the rubber ring 301 expands at the position of the first cavity 302 to seal the connection between the inner wall positions of the connecting pipe 1 and the connecting elbow pipe 2, and the rubber ring 301 expands at the position of the second cavity 303 to fill the gap between the fixed shell 304 and the connecting pipe 1 and the connecting elbow pipe 2, make connecting pipe 1 and connecting bent pipe 2 connect more firmly between radial, and then reduce the radial vibrations between connecting pipe 1 and connecting bent pipe 2, thereby avoid the production of noise, rubber ring 301 is located and can also play the effect of buffering connecting pipe 1 and connecting bent pipe 2 axial vibrations between connecting pipe 1 and connecting bent pipe 2 simultaneously, reduce the noise that produces because of vibrations, thereby realized avoiding producing the condition emergence that vibrations caused the noise to produce because of the insecure connection and produce the noise, through setting up communicating pipe 305, avoid connecting pipe 1 and connecting bent pipe 2 to rubber ring 301 mutual extrusion cause first cavity 302 and second cavity 303 not to take place, because of the existence of barb 617 when rotating ring 605 rotates, can drive two to be semi-annular rotating ring 605 and can only rotate clockwise, when a rotating ring 605 is swing joint respectively on the surface of upper clamp powder 4 and lower clamp powder 5, and through the effect that the worm 603 and the worm wheel 604 can only transmit in a single phase, the upper clamp powder 4 and the lower clamp powder 5 can be prevented from being separated through the barb 617, the upper clamp powder 4 and the lower clamp powder 5 can be assembled stably through the matching of the fixing ring 906, compared with the condition that the upper clamp powder 4 and the lower clamp powder 5 are fixed in a screw manner, the wire can not be separated, and no special tool is needed for installation, the upper clamp powder 4 and the lower clamp powder 5 are not easy to separate, when the device needs to be disassembled, the movable rod 607 is pressed, and the movable rod 607 drives the limit block 613 to extrude the return spring 614 until the movable rod 607 moves to the inner wall of the rotating ring 605, at this time, under the effect of the return contraction of the fixed block 611, the fixed block 611 drives the movable block 610 to return to the initial position, at this time, the worm wheel 604 continues to drive the rotating ring 605 to rotate through the worm wheel 604 until the two rotating rings 605 are respectively located on the surfaces of the upper clamp powder 4 and the lower clamp powder 5, at this moment, the fixing ring 906 is separated from the positioning pipe 903, the upper clamp powder 4 and the lower clamp powder 5 can be separated, the operation is simple, the disassembly and the assembly are convenient, the limiting rod 10 and the limiting track 11 are arranged, the rotating ring 605 is prevented from falling off when the surfaces of the upper clamp powder 4 and the lower clamp powder 5 rotate, and the fixing block 611 is arranged to play a role in positioning the fixing shell 304.
