[0070] In an embodiment of the present application, preferably, as Figure 18As shown, the inner pipe fitting 24 and the outer pipe fitting 23 are slidably connected through a slide rail and a slider.
[0071] In this embodiment, the inner pipe fitting 24 and the outer pipe fitting 23 are slidably connected. While serving as a sliding guide, they can also avoid interference. It should be noted that: to distinguish the slide rails and sliders at other positions, the slide rail here is called the second slide rail 213, and the slider here is called the second slider 214. Preferably, the second slide rail 213 is fixed on the outer pipe fitting 23, and the second slider 214 is fixed on the inner pipe fitting 24. Of course, it is not limited to this. It is also possible to fix the inner pipe fitting 24 on the outer pipe fitting 23 and fix the second slide rail 213 on the inner pipe fitting 24.
[0072] In an embodiment of the present application, preferably, as Figure 14 shown, the pushing positive hook device further includes a trigger sensor 215 and a trigger member 216; wherein, one of the trigger sensor 215 and the trigger member 216 is arranged on the outer pipe fitting 23, and the other is arranged on the positive hook base 22. The trigger sensor 215 and the trigger member 216 are sequentially arranged at intervals along a first preset direction. And when the outer pipe fitting 23 moves along the first preset direction towards the hook to be positively hooked to the first extreme position, the trigger member 216 is used to trigger the trigger sensor 215 so that the outer pipe fitting 23 stops advancing.
[0073] In this embodiment, when the outer pipe fitting 23 moves along the first preset direction towards the hook to be positively hooked to the first extreme position, the trigger member 216 will trigger the trigger sensor 215, thereby obtaining that the outer pipe fitting 23 has moved to the extreme position at this time. Furthermore, the driving device can be made to stop working, so that the outer pipe fitting 23 and the inner pipe fitting 24 no longer continue to move forward, avoiding the separation of the slider and the slide rail described below, which may cause the structure to fail. Of course, it is not limited to the above. Other layout methods can also be adopted. For example: the trigger sensor 215 is arranged on the outer pipe fitting 23, and the trigger member 216 is arranged on the positive hook base 22, which is specifically selected according to actual needs. Further, preferably, the trigger member 216 can be an L-shaped metal part. Of course, it is not limited to this and can also be designed according to actual needs.

The second limiting member 218 is disposed on the hooking base 22, and at least a part of its structure extends into the installation cavity. The first limiting member 217 and the second limiting member 218 are sequentially arranged at intervals along a first preset direction. When the outer pipe fitting 23 moves along the first preset direction towards the coupler to be hooked to the second extreme position, the first limiting member 217 touches the second limiting member 218, so that the outer pipe fitting 23 stops advancing.
[0075] In this embodiment, the foregoing triggering sensor 215 and triggering member 216 serve as the first-stage limit. When the first-stage limit fails, the second-stage limit can be adopted. Then, when the first-stage limit fails, the outer pipe fitting 23 and the inner pipe fitting 24 will continue to move forward. When moving to the second extreme position, the first limiting member 217 will touch the first limiting member 217, thereby forcing the outer pipe fitting 23 and the inner pipe fitting 24 to stop advancing. It can be seen that the present application is provided with a double limit, which is safer and more reliable. Of course, it is not limited to this. It is also possible to only set one limit structure, for example, only set the limit structure of the foregoing triggering sensor 215 and triggering member 216, or only set the limit structure of the foregoing first limiting member 217 and second limiting member 218.
[0076] Further, preferably, the first limiting member 217 is an L-shaped block, and a part of it is arranged along the horizontal direction, and the other part of it is arranged along the vertical direction.

The second rack 221 is disposed on the outer pipe fitting 23 and extends along the first preset direction, and the second rack 221 meshes with the second gear 220.
[0079] In this embodiment, the positive hook driving device 21 drives the gear to rotate, and the second gear 220 drives the second rack 221 to move. Since the second rack 221 is fixed to the outer pipe fitting 23, the outer pipe fitting 23 is driven to move. Of course, the transmission mechanism is not limited to the above, and can also be selected according to actual needs.

Of course, it is not limited to this. Instead of setting this bottom support member 222, the positive hook base 22 can be simply heightened to achieve the above function.
[0082] In an embodiment of the present application, preferably, as Figure 17 shown, the outer pipe fitting 23 is formed with an avoidance notch 231 for avoiding the chain 253 to prevent interference. Further, preferably, the number of the avoidance notches 231 is two, and they are respectively arranged along the first preset direction corresponding to the turning points of the annular chain 253.
