The first mounting ring 6 and the second mounting ring 7 facilitate splicing of the first sheath 4 and the second sheath 5, and the second mounting ring 7 is provided with a card slot 8 on the inner side, up and down, front and back, and the second mounting ring 7 is provided with slots 10 on the upper, lower, front and rear sides of the outer side to facilitate the passage of the extrusion block 14. The upper, lower, front and rear ends of the right side of the first mounting ring 6 are fixedly connected with U-shaped card plates 12. The U-shaped card plate 12 has toughness. Two first springs 13 are fixedly connected inside the U-shaped card plate 12 to make the resetting effect of the U-shaped card plate 12 better. The extrusion block 14 is fixedly connected to the outer side of the U-shaped card plate 12 to facilitate the control of the contraction of the U-shaped card plate 12. Insert blocks 16 are provided between the four adjacent U-shaped card plates 12. The insert blocks 16 are fixedly connected to the first mounting ring 6. Plug holes 15 are provided between the four adjacent slots 8, and the plug holes 15 are opened on the left side of the second mounting ring 7. A sealing component is provided at the right end of the first sheath 4.

[0032] Reference Figure 3 The sealing assembly includes an installation groove 17, which facilitates the expansion and contraction of the telescopic ring 19 inside. The installation groove 17 is opened on the right side of the first sheath 4. A uniformly distributed second spring 18 is fixedly connected in the installation groove 17. The telescopic ring 19 can be expanded and contracted in the installation groove 17 through the second spring 18. The other end of the second spring 18 is fixedly connected to the telescopic ring 19. The telescopic ring 19 is arranged in the installation groove 17, and the outside of the telescopic ring 19 is slidably connected to the inner wall of the installation groove 17.

[0033] Reference Figure 2 and Figure 3 The slot 10 runs through the card slot 8, and two limit blocks 9 are fixedly connected in the card slot 8. The limit blocks 9 are arranged on both sides of the slot 10. A sealing ring 11 is fixedly connected to the left end of the second sheath 5. The position of the sealing ring 11 corresponds to the position of the sealing assembly. The extrusion block 14 is arranged in the slot 10, and the outer part of the extrusion block 14 is slidably connected to the inner wall of the slot 10. When the U-shaped card plate 12 is inserted into the card slot 8, the extrusion block 14 is driven to slide in the slot 10. The plug block 16 is arranged in the socket 15, and the outer part of the plug block 16 is slidably connected to the inner wall of the socket 15. Inserting the plug block 16 into the socket 15 can improve the stability of the connection.

[0034] Working principle: When the extended sheath needs to be spliced, the four plug blocks 16 and the four U-shaped card plates 12 on the first sheath 4 and the first mounting ring 6 are inserted into the plug holes 15 and the card slots 8 on the second sheath 5 and the second mounting ring 7. The U-shaped card plate 12 with toughness is squeezed by the limit block 9 to squeeze the first spring 13 to contract, and the squeeze block 14 enters the slot 10. When the U-shaped card plate 12 completely enters the card slot 8, the U-shaped card plate 12 is separated from the squeeze of the limit block 9, thereby resetting and stretching in the card slot 8. The U-shaped card plate 12 is limited by the limit block 9 so that the U-shaped card plate 12 is in the card slot 8, thereby achieving The first sheath 4 and the second sheath 5 are now spliced ​​and installed. When disassembly is required, the extrusion block 14 is pressed by hand to contract through the U-shaped card plate 12, so that the end of the U-shaped card plate 12 is free from the restriction of the limit block 9, and the first sheath 4 and the second sheath 5 can be disassembled. When the first sheath 4 and the second sheath 5 are spliced, the sealing ring 11 on the second sheath 5 is inserted into the installation groove 17 on the first sheath 4, and the sealing ring 11 squeezes the telescopic ring 19 and the second spring 18 in the installation groove 17. The second spring 18 can drive the telescopic ring 19 to expand and contract in the installation groove 17, so that the sealing ring 11 and the telescopic ring 19 are more closely fitted, and the sealing effect is better.
