[0023] More specifically, the sealing assembly 3 is sealed for the second time by setting the air stop valve 4 to prevent gas leakage after long-term use. When replacing, the protective plate frame 21 is first pulled out to the front with force. Under the action of the force, the clamping rod 15 is disengaged from the inner cavity of the positioning groove 16. At the same time, the first spring 14 is deformed and drives the replacement sleeve seat 23 to move toward the front, so that it is replaced. When sealing the cable, the cable first needs to pass through the inner cavity of the replacement sleeve seat 23, and then the air stop valve 4 is rotated. Under the action of the pump, the gas is introduced into the inner cavity of the ventilation pipe 32 through the air stop valve 4 in turn, and under the action of the air pressure, the moving rod 33 drives the sealing plate 36 to move toward the front, and then the gas enters the inner cavity of the sealing airbag 31, and the sealing airbag 31 is inflated, thereby sealing and wrapping the cable, which has the advantages of good sealing effect and convenient replacement.

[0024] In some embodiments, the card slots 13 are opened on both sides of the fixed housing 11, and the first spring 14 is fixedly installed in the inner cavity of the card slot 13. More specifically, the first spring 14 is installed by setting the card slot 13, so that the card rod 15 is reset.

More specifically, the position of the sleeve shell 22 is fixed by setting the card rod 15, and the outside of the card rod 15 is limited by setting the positioning grooves 16.

[0026] In some embodiments, the outer side of the clamping rod 15 passes through the positioning groove 16 to the interior of the sleeve shell 22, and the sliding grooves 34 are opened on both sides of the inner cavity of the ventilation pipe 32. More specifically, the gap between the fixed sleeve 11 and the replacement sleeve seat 23 is sealed by setting a first sealing ring 12, and the slider 35 is limited by setting the sliding groove 34 to prevent the slider 35 from shaking during the movement.

[0027] In some embodiments, the movable rod 33 is arranged in the inner cavity of the ventilation tube 32, and the front of the movable rod 33 is fixedly connected to the back of the blocking plate 36. More specifically, the blocking plate 36 is limited by setting the movable rod 33 to prevent the blocking plate 36 from shaking during the movement.

[0028] In some embodiments, the slider 35 slides in the inner cavity of the slide groove 34, and the relatively close side of the slider 35 is fixedly connected to the two sides of the moving rod 33. More specifically, the moving rod 33 is limited by setting the slider 35 to prevent the moving rod 33 from shaking during the movement.

[0029] In some embodiments, a second spring 37 is fixedly installed in the inner cavity of the slide groove 34 and on the front side of the slider 35. The relatively close side of the blocking airbag 31 is connected through a catheter. More specifically, the slider 35 is reset by setting the second spring 37, thereby indirectly blocking the blocking airbag 31.

[0030] Working principle:

[0031] Step 1: When replacing, first pull the protective plate frame 21 forward with force. Under the action of the force, the clamping rod 15 is separated from the inner cavity of the positioning groove 16. At the same time, the first spring 14 is deformed and drives the replacement sleeve seat 23 to move forward, thereby replacing it;

[0032] Step 2: When sealing the cable, the cable first needs to pass through the inner cavity of the replacement sleeve seat 23, and then the air stop valve 4 is rotated. Under the action of the pump, the gas is introduced into the inner cavity of the ventilation pipe 32 through the air stop valve 4 in turn, and under the action of air pressure, the moving rod 33 drives the sealing plate 36 to move toward the front, and then the gas enters the inner cavity of the sealing airbag 31, and the sealing airbag 31 is inflated, thereby sealing and wrapping the cable, which has the advantages of good sealing effect and convenient replacement.
