[0023] In this embodiment, by pulling the outer tube 8 and the inner tube 18 on both sides, the outer tube 8 slides along the groove 181 opened on the surface of the inner tube 18 under the action of the pulling force, thereby extending the telescopic tube, which is more convenient to operate when used in narrow areas.

[0024] Example 2

[0025] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a sealing guide sleeve 12 is fixedly connected to one side of the sixth connecting flange 11, a first sealing ring 13 is fixedly connected to one end of the inner wall of the sealing guide sleeve 12, a second sealing ring 14 is fixedly connected to the other end of the inner wall of the sealing guide sleeve 12, a seventh connecting flange 15 is fixedly connected to one end of the sealing guide sleeve 12 away from the sixth connecting flange 11, and a sealing flange 15 is bolted to one side of the seventh connecting flange 15 away from the sealing guide sleeve 12. 6. The inner wall of the sealing flange 16 is fixedly connected with the third sealing ring 17, the inner wall of the third sealing ring 17 is overlapped with the inner tube 18, the surface of the inner tube 18 is slidably connected with the inner wall of the outer tube 8, the surface of the inner tube 18 is provided with a groove 181, the inner wall of the groove 181 overlaps with the inner wall of the first sealing ring 13, the inner wall of the third sealing ring 17 overlaps with the inner wall of the groove 181, the inner wall of the second sealing ring 14 overlaps with the inner wall of the groove 181, and the inner wall of the rubber limit ring 10 overlaps with the inner wall of the groove 181.
