In addition, a pressure pad 9 for sleeving the external pipeline 4 is further arranged between the pipe clamp 61 and the second sealing element 8, one end of the pressure pad 9 is abutted against the pipe clamp 61, and the other end of the pressure pad is abutted against the second sealing element 8. In this embodiment, when in use, the outer surface of the external pipe 4 is sequentially sleeved with the first locking nut 62, the pipe clamp 61, the pressure pad 9 and the second sealing member 8, and one end of the external pipe 4 is inserted into the bottom of the socket 5, when the first locking nut 62 is screwed, the first locking nut 62 makes an axial linear motion, and due to the arrangement of the tapered structure, the pipe clamp 61 can press the outer peripheral surface of the external pipe 4 under the action of a radial force and clamp the external pipe 4; the axial force of the first lock nut 62 compresses the pressure pad 9 and the second sealing element 8, and the pressure of the second sealing element 8 is increased, so that the radial sealing of the outer surface of the external pipeline 4 is firmer, and the internal pressure is ensured to be watertight.

Wherein, the inner wall of the socket 5 is provided with a positioning block 10 for limiting the external pipeline 4. In the present embodiment, since the inner wall of the socket 5 is provided with the positioning block 10, the external pipe 4 is inserted into the socket 5 at one end of the external pipe 4, and when the end of the external pipe 4 abuts against the positioning block 10, it is described that the external pipe 4 is completely inserted into the socket 5. The positioning block 10 may be an annular structure provided on the inner wall of the socket 5 in the circumferential direction.

In addition, the first telescopic body 1 is sleeved inside the second telescopic body 2, and the second telescopic body 2 is provided with a limiting structure 11 for preventing the first telescopic body 1 from separating from the inside of the second telescopic body 2. In this embodiment, when adjusting the length of flexible quick-operation joint, because limit structure 11's setting, can prevent first flexible body 1 at the inside gliding in-process of the flexible body 2 of second, first flexible body 1 breaks away from the flexible body 2 of second is inside.

The limiting structure 11 comprises a second boss 111 arranged at one end of the first telescopic body 1 inside the second telescopic body 2, a stop ring 112 mounted on the end of the second telescopic body 2 and used for limiting the second boss 111, and a fastener 113 used for fixing the stop ring 112 on the second telescopic body 2; the stop ring 112 is located at the end of the second telescopic body 2 remote from the socket 5. In the present embodiment, the stop ring 112 is mounted at an end of the second telescopic body 2 far from the socket 5 thereof and is fixed by the fastener 113, and the stop ring 112 can prevent the first telescopic body 1 from being separated from the inside of the second telescopic body 2 by the abutting action between the stop ring 112 and the second boss 111. It should be noted that the fastening member 113 may be detachably connected to the second telescopic body 2, or may be fixedly connected to the second telescopic body 2.

In addition, the fastening member 113 includes a second locking nut 1131 screwed with the second telescopic body 2 and a fixing ring 1132 connected to an end of the second locking nut 1131 far from the socket 5 of the second telescopic body 2 and used for fixing the stop ring 112 on the second telescopic body 2.
