The limiting block 1033 fixed at the top end of the upper surface of the third coupling slope 1031 and the sliding rod 1034 on the surface of the coupling tube 103 are matched with the locking sleeve 104 on the outer surface of the coupling tube 103, the limiting block 1033 is used for preventing the locking sleeve 104 from accidentally sliding off, and the two sliding rods 1034 symmetrically arranged on the surface of the coupling tube 103 are in sliding fit with the locking sleeve 104.

The guiding rod 1035 is tightly attached to the inner wall of the coupling tube 103 and is located in the middle position of the coupling tube 103, when the connecting tube 101 is coupled to the coupling tube 103, one end of the guiding rod 1035 in the direction close to the third coupling slope 1031 enters a limit groove 1026 on the lower surface of the locking tube 102, slides in the limit groove 1026, and is tightly attached to the coupling of the first coupling slope 1011 and the third coupling slope 1031 through the limit groove 1026 on the surface of the locking tube 102, so that the connecting tube 101 and the coupling tube 103 are limited in the axial direction during coupling connection, and cannot rotate after coupling.
The limit bars 1036 are arranged on the inner wall of the coupling tube 103 in an array mode, the outside of each limit bar 1036 is connected with a guide bar 1037, objects entering the coupling tube 103 are limited in shape through the limit bars 1036 and the guide bars 1037, and the objects are limited through the second screw 1038 above, so that the objects are locked in the coupling tube 103.
Preferably, referring to fig. 5 to 8, a locking block 1041 is disposed on an inner wall of the locking sleeve 104, an end portion of the locking block 1041 extends to an inner wall of the locking groove 1032 and is slidably matched with the locking block, a sliding groove 1042 is further disposed on an inner wall of the locking sleeve 104, the sliding groove 1042 is slidably matched with the sliding rod 1034, and locking holes 1043 are disposed on an inner wall array of the locking sleeve 104.
Wherein the locking block 1041 on the inner surface of the locking sleeve 104 slides inside the locking groove 1032 on the surface of the third coupling slope 1031, and the sliding groove 1042 on the inner surface of the locking sleeve 104 is wrapped outside the sliding bar 1034 on the outer surface of the coupling tube 103, preventing the locking sleeve 104 from deflecting and fixing the locking sleeve 104 outside the coupling tube 103 when sliding.
When the locking sleeve 104 is initially arranged, the locking block 1041 of the inner wall is positioned at the left side of the locking groove 1032, when the connecting pipe 101 is coupled with the coupling pipe 103, the locking pipe 102 outside the connecting pipe 101 enters into the coupling pipe 103, the locking rod 1021 is tightly attached to the inner wall of the coupling pipe 103, after the two are tightly attached, the slope 1023 of the outer surface of the locking rod 1021 integrally enters into the locking groove 1032, the clamping surface 1025 of the surface of the slope 1023 is attached to the right side surface of the locking groove 1032, and the self-locking of the connecting pipe 101 and the coupling pipe 103 is realized through the slope 1023.
When unlocking is needed, the locking sleeve 104 is slid, the locking block 1041 on the inner surface of the locking sleeve 104 slides from left to right in the locking groove 1032, slides from the bottom of the slope 1023 on the surface of the locking rod 1021 to the high position of the slope 1023, at this time, the bottom surface of the locking block 1041 starts to be tightly attached to the surface of the slope 1023, and as the locking sleeve 104 slides, the locking block 1041 gradually slides to the highest position of the slope 1023, that is, the position of the concave ring 1024 on the surface of the slope 1023, and because the surface of the locking sleeve 104 is limited by the sliding of the sliding rods 1034 on both sides, the locking sleeve 104 only translates and does not move obliquely upwards in the sliding process, so that the locking block 1041 on the inner wall of the locking sleeve 104 presses the slope 1023 downwards.
Along with the upward sliding of the locking block 1041 along the slope 1023, the locking block 1041 also presses the slope 1023 downward, the tail end position of the locking rod 1021 is downward, the engagement surface 1025 outside the slope 1023 is downward, and loses contact with the right side surface of the locking groove 1032, so that the locking effect on the connecting pipe 101 is lost, and at this time, the connecting pipe 101 can be pulled out, so that the connecting pipe 101 and the coupling pipe 103 are separated.
In summary, when the connecting pipe 101 is guided to the vicinity of the coupling pipe 103 during use, the locking pipe 102 at the front end of the connecting pipe 101 gradually enters the coupling pipe 103, it should be noted that the shape of the holding portion between the connecting pipe 101 and the coupling pipe 103 is not the only shape, and the outer wall may be a circular shape or a square shape. Meanwhile, the locking block 1041 of the locking sleeve 104 is maintained at the initial position of the locking groove 1032, and the locking state between the connection pipe 101 and the coupling pipe 103 is ensured by the self-locking mechanism of the slope 1023.
When the locking state between the connecting pipe 101 and the coupling pipe 103 needs to be released, the operator slides the locking sleeve 104, so that the locking block 1041 on the inner wall of the locking sleeve 104 slides from left to right along the locking groove 1032, the bottom surface of the locking block 1041 slides upward on the surface of the slope 1023, and as the locking block 1041 applies downward pressure to the slope 1023, the engagement surface 1025 of the locking rod 1021 is gradually separated from the right side surface of the locking groove 1032, thereby releasing the locking, and at this time, the connecting pipe 101 can be smoothly pulled out from the coupling pipe 103, and the whole unlocking and separating process is completed.
